1 General Remarks

1.1 Licensing

PSS SINCAL 9.5 Platform uses the same license file as the preceding PSS SINCAL 9.0 version.

Simply copy the existing license file to the "Bin" directory of PSS SINCAL Platform Installation

(normally this is "C:\Program Files\PTI\PSS SINCAL 9.5\Bin").

If you need a new license file or have any questions about the licensing, please contact the

PSS SINCAL Support (phone +43 699 12364435, e-mail [email protected]).

2 PSS SINCAL

2.1 User Interface

Modified Currency Implementation

How currencies are used in PSS SINCAL has been completely redesigned, since this was rather

confusing and also impractical. Up until now, there was a stand-alone table "EcoCurrency", where

both the currencies and their conversion factors for the base currency were defined.

The new way currencies are implemented in PSS has been designed in the same way as in other

network planning systems. Attributes that include costs are specifically identified: e.g. acquisition

costs, installation costs or even costs for energy malfunction per year. For these attributes, you can

select any currency symbol you want. The initial settings are made in the document settings and can

be done individually for each PSS SINCAL network. These symbols can be changed at any time, and

no currency conversion is performed.

New Functions in the Diagram System

A number of diagrams require the same scaling for the X and y axis to make an evaluation as

meaningful as possible. This is, for example, important when working with impedance diagrams for

protection devices, but also for the locus curves of harmonic calculations. Up until now, this feature

was not available in PSS SINCAL and the same scaling for the x and y axis had to be selected

manually. This is now done automatically in the respective diagrams.

Illustration: Result diagram harmonics with locus curve

Another new feature is assigning user-defined formulas for data series. A universal formula parser

is available so that the data series can be converted before it is presented. A simple example is

changing the unit (e.g. of MW to kW). This also makes completely different calculations possible,

such as the converting of p.u. values to real values, and much more.

The user-defined formulas can be assigned individually to the data series in the diagram. The

formula itself is stored in the .dia file analogous to the other settings. For editing of the formula, there

is a new dialog box that can be opened from the Data Series tab in the Format Diagram dialog box.

Illustration: Dialog box for Edit Data Series

In addition to converting with a formula, optional post processing of the signal can also be performed.

In this example, this is the RMS function (quadratic mean value). A current quadratic mean value is

calculated over a specified time period with a variable sampling frequency. This means that you can,


Release Information

April 2013 4/33

for example, convert the results of the EMT simulation and display these directly in the diagram

without having to recalculate.

Another new feature allows you to set the min- and max-values for the signal. In this way, the limit

values, to which auto-scaling is limited, can be prescribed. This means, if the values of the data

series are under the indicated limits, then auto-scaling uses these minimum and maximum values. If

the values of the data series, however, are larger, the actual minimum or maximum from the data

series are used.

Enhanced Workspace Functions

The functions for exporting and importing workspaces have been enhanced. You can now also save

the evaluation settings in the workspace and then simply apply them to another PSS SINCAL

network.

Displaying Large Numbers in Network Diagrams and Tables

Displaying numeric values in the network diagram and in the tabular view has been improved. To

make large numeric values easier to read, these are now displayed separated into groups of

thousands analogous to the data screen form.

Illustration: Displaying numerical values in data screen forms and network diagrams

This option is particularly valuable for the results of the Economic Efficiency calculations, where

larger amounts for costs often need to be displayed.

Improved Updating of Tables

How tabular views are updated has been improved. You can now scroll through the results, even

when the table is open. PSS SINCAL automatically updates the display in the table, analogous to the

network diagram.


Release Information

April 2013 5/33

Illustration: Scrolling through the results in open tabular view

Improved Selection of Results during Variant Change

When changing variants, now the results that were also selected in the current variant are

preselected in the variant to be opened. This is particularly practical in harmonics, load profile and

load development calculations, because this makes it much easier to compare results.

2.2 Electrical Networks

New 4-Wire Load Flow

Due to the current demands for even more exact planning of electrical distribution and transmission

networks, these also have to be modeled in greater detail in the simulation procedures. In reference

to the network display, this means that the networks are simulated as 4-wire systems (three

conductors and the return conductor). The network is displayed in the simulation just as in reality and

a more detailed observation of the network state is possible.

The simulation module for electrical networks in PSS SINCAL has been developed based on the

MGN system. Originally only symmetrical networks with symmetrical and asymmetrical faults were

calculated. In the course of replacing the product PSS ADEPT, the simulation procedures have been

enhanced so that asymmetrical networks can now also be calculated. The calculations, however, are

done in the MGN system. This means that the asymmetrical network is converted to a MGN

equivalent and then calculated. From an electricity standpoint, this is correct, but problems arise

when specific analyses and evaluations are required. Because of the MGN system, return

conductors and ground are not available separately any more. Thus neither currents nor voltages in

the return conductor can be determined. Modeling of more complex neutral point configurations in

the MGN system is also limited. Additional problems arise when special modeling of asymmetrical

network elements is required, for example, that of center-tapped-transformers.

To solve these problems, 4-wire load flow is now available in PSS SINCAL. This has been integrated

as an additional load flow procedure that can be selected in the calculation settings analogous to the

already available procedures. The new 4-wire load flow uses precisely the same input data as all

other load flow procedures. The main difference is that here the return conductor and the transition

from the return conductor to the ground can be modeled. This means that the network is constructed

in a physically accurate manner with all four phases, i.e. RSTN, and the grounding impedances can

also be modeled.


Release Information

April 2013 6/33

The modeling of the return conductors is done with the lines. Either the zero-phase sequence can be

defined as before, or the data of the return conductor are directly defined. This is done in the section

Zero-Phase Sequence. PSS SINCAL has the following input options:

Ratios of x0/x1 and r0/r1:

PSS SINCAL calculates the values for r and x in the zero-phase sequence from the ratio

specified in the fields for Zero/Pos. Resistance, Zero/Pos. Reactance and Zero Seq.

Capacitance.

Entering the values r0 and x0 directly:

PSS SINCAL applies the values for r and x in the zero-phase sequence from the fields for Zero

Seq. Resistance, Zero Seq. Reactance and Zero Seq. Capacitance.

Entering the values rR and xR:

This option defines a return conductor with real values. The data of the return conductor are

defined in the fields for Return Conductor Resistance, Return Conductor Reactance, and Return

Conductor Capacitance.

Illustration: Line input data

If only one return conductor is to be modeled, then the phase selection has to be set to "N". In this

case, the positive-phase sequence data of the line are considered as blocking.

To model the connection of the neutral points of network elements to the return conductor or to the

ground, the neutral point impedance is available. The neutral point impedance can be assigned to

generators, transformers, and even to nodes and busbars.


Release Information

April 2013 7/33

Illustration: Neutral point impedance at a two-winding transformer

The following illustration shows switching of two transformers with a common neutral point, where

also a grounding impedance ZG has been defined.

Illustration: Switching with neutral point impedances

In PSS SINCAL this kind of switching is modeled with help of 2 neutral point impedances, where one

is allocated to transformer T1 and the other to transformer T2. A common neutral point impedance

with grounding impedance is allocated to these neutral point impedances.

Better Performance for Contingency Analysis

The time required for calculating the contingency analysis, mainly in larger networks, is determined

exclusively by the load flow calculations. This is because many thousand load flow calculations are

performed in order to find the significant malfunctions. This, however, result in many unnecessary

load flow calculations being carried out that yield no significant effects of the malfunctions on the

network.

Since the load flow algorithms in PSS SINCAL have already been optimized for the most part, no

significant increase in speed can be achieved in these areas. The approach to solving the problem of

increasing performance is the following: which combinations of malfunctions lead to problems in the

network is already determined prior to the individual load flow calculations. This calculation can be

done mathematically using the base load flow of the network. Based on certain characteristics, the

calculations can then be limited to the malfunctions significant to the network.

The evaluation of the effects of a malfunction is done in the course of a load flow calculation of the

basic network. After this load flow all currents as well as voltages in the undisturbed network are

known. It is assumed that the malfunction of an element changes the current and voltage distribution

in the network. This change can be approximately simulated, by placing negative currents or powers

at the malfunctioning serial elements and then solving the matrix. This way the power flow becomes

zero via the serial element. Thus this represents a simplified version of the malfunction of the

element. Then the resulting voltage changes at the nodes in the network can be used as an indicator

for the evaluation of the malfunction. The greater the voltage changes are, the more serious are the

consequences of the malfunction.

The voltage change can also be used to determine the power change of loads. In addition to this

evaluation, not-supplied elements must be identified with network tracing. With these determined

data, the individual malfunctions can be weighted and ranked. To increase performance not all

malfunction combinations are calculated as before, but rather only a defined number – i.e. the top "n"

malfunctions. Sequencing based on weighting ensures that the problematic malfunctions are

calculated first.

Switching ON the new functions is very simple. Before the start of the contingency analysis, a dialog

box is displayed in which the settings for the behavior of the simulation procedure can be made.

Illustration: Dialog box for controlling the Contingency Analysis

Mode controls how the contingency analysis should work:

Normal:

The contingency analysis is carried out without a preanalysis or reduction.


Release Information

April 2013 9/33

Reduced:

A reduced contingency analysis is carried out, i.e. the analysis is done for a predefined number

of malfunctions. The sequence of the malfunctions is the result of a preanalysis.

Preanalysis:

A preanalysis is carried out where all malfunctions are weighted according to evaluation settings.

The Assessment section defines which options are used for weighting the malfunctions.

Voltage change:

The resulting voltage changes at the nodes are used as an indicator for the evaluation of the

malfunction.

Not delivered power:

The power change at the load is used for the evaluation.

Not supplied elements:

Unsupplied elements are used for the evaluation.

Not supplied loads:

Unsupplied loads are used for the evaluation.

Another new optional control option to restrict the number of possible malfunctions is Unavailability.

Unavailability is determined based on the failure frequency Hu and outage duration Tu for reliability

input data. The determination can either be based on the data of the short or the long independent

single failure. Within the scope of the contingency analysis, only those elements, whose unavailability

exceeds the limit defined in the dialog box, will fail.

Control of the Scope of the Results for LF Calculations

In large networks it is useful to reduce the scope of the results for some calculation methods. Typical

examples are the load profile and load development calculations. When working with a large network

with many thousand nodes, load profiles are calculated over a longer time period, many gigabytes of

output data can quickly accumulate. The problem is that results are provided for all elements and

nodes in the network, even when these are not of interest.

For this reason, PSS SINCAL now offers the possibility of reducing the scope of the results manually.

This is done by marking the nodes and network elements (or, to be more precise, their terminals).

After a specific configuration in the calculation settings, only result diagrams and load flow results for

marked elements are provided. The definition for diagrams is done in the basic data with the attribute

Diagram Creation, and the definition for load flow with the attribute Store Results.


Release Information

April 2013 10/33

Illustration: Controlling the scope of the results for the load flow calculations

To control the storage of the results, PSS SINCAL has the following options:

Due to method:

This option automatically stores the results according to the simulation method selected.

Completely:

All results are stored in the database.

Violations:

Only results for network elements exceeding the limits are stored.

All elements in case of violations:

If the limits are exceeded, the results for the entire network are stored.

Marked:

Only results for marked nodes and elements are stored.

Marked or violations:

PSS SINCAL saves results for marked nodes and elements, and for nodes and for elements with

violations.

To simplify marking the nodes and network elements, the Set Input State dialog box has been

enhanced. For the marking, the desired elements are selected in the Graphics Editor and the dialog

box is opened with Edit – Set Input State in the menu.

Illustration: Dialog box for setting the input state

Enhanced Log File for Calculation Methods

The log file contains general information for the calculation (e.g.: databases used, active Include

networks, start and stopping times of the calculations, ...) and also error messages and warning

messages. In addition, the log file is also used for the output of diagnosis messages. Up until now,

the log file was only available for the dynamics simulation in the reliability calculations, now, however,

it is generated by all calculation methods.

The log file is usually displayed in the message window. Since the log file is a simple HTML-file,

which is stored in the "_files" directory of the network, it can also be displayed without any problems

using an external web browser.

The amount of output data into the log file can be defined in the Basic Data of the Calculation

Settings with the Log File Level field. The following options are available:

● Low:

Only minimal information is written into the log file.

● Standard:

The amount of information in the log file is selected so that the course of the simulation can be

reconstructed and potential problems can be analyzed.

● Advanced:

Very comprehensive information is provided in the log file. This information is mainly useful for

detailed analysis in the reliability calculations, since each individual load flow is documented in

detail.

Enhanced Documentation for Load Flow and Short Circuit Results

In the course of PSS SINCAL load flow and short circuit calculations, a large number of results are

provided. Up until now, however, these results were not sufficiently documented. Now

comprehensive documentation is available for all the results of the following calculation methods:

Load flow

Unbalanced load flow

Short circuit 1-, 2-, 3-phase according to VDE/IEC/G74

ANSI Short Circuit 1-, 2-, 3-phase

The documentation of the results is contained in the respective procedure description and can be

activated in the user interface very easily from the screen forms for results.


Release Information

April 2013 12/33

Connecting Nodes for Calculations

This feature is used to connect two separate nodes for the calculations electrically. The technique is

exactly the same as the one used to connect the nodes in Include networks, but this is now also

possible within one network.

The usage is as simple as possible. To connect two or more nodes, all nodes are assigned the same

connection name. In addition, connecting within a network must be switched ON in the calculation

settings.

Illustration: Options for connecting two nodes

Enhanced ISO Evaluations

To visualize the results of the load flow calculations, new evaluations are available:

Load Flow: S

This evaluation displays both the supply sources and the consumers.

Load Flow: S (consumer)

This evaluation visualizes only the consumers.

Load Flow: S (supply)

This evaluation visualizes only the supply sources.


Release Information

April 2013 13/33

Illustration: New ISO evaluation

New Result Diagrams for Load Development

The new result diagrams of the load development have been designed in a way analogous to the

load profile calculations. All results that are available for a period of time are prepared as signals that

can be combined any way you want in the diagrams.

To customize the diagrams, there is a special dialog box to administer all the result signals for load

development. The dialog box to define the diagram page provides all diagrams available on the page

and their assigned signals in the list on the left. The right list contains all the available signals. These

are organized according to type and element hierarchically. You can easily find the desired signals

using the special filter functions.


Release Information

April 2013 14/33

Illustration: New load development diagrams

The scope of the result diagrams has also been enhanced. Up until now, only the utilization of the

elements was available, but this was insufficient for a detailed analysis of the network. For this

reason, there are now new result diagrams. The scope of the results is based once again on the load

profile calculations. PSS SINCAL has the following new diagrams:

Node

o Voltage

o Active power

o Reactive power

Element

o Utilization

o Active power

o Reactive power

In asymmetrical calculations, the diagrams are prepared for the individual phases.

Enhanced Harmonics Data for DC-Infeeders

The harmonics input data for the DC-infeeders have been enhanced. Now the same entries as for

general load are possible, i.e. an independent control current can be defined for the harmonic

calculations.

Improved Implementation of the Observation Branch Results

The implementation of the observation branch results of the short circuit calculations has been

improved. The corresponding results are now also directly available in the pop-up menu.


Release Information

April 2013 15/33

Improved Editing of the Teleprotection of Protection Devices

The protection device dialog boxes have been enhanced to enable improved editing of teleprotection.

Illustration: Teleprotections in the Protection Device dialog box

Teleprotections are now available in the browser of the dialog box. There are two different points

under which all the Teleprotections affecting the current device can be displayed:

Teleprotection – Sender

The device sends a signal to another device.

Teleprotection – Receiver

The device receives a teleprotection.

New Teleprotections can simply be created or deleted in the pop-up menu in the browser. The

previous functions for editing using the Data – Protection Device Coordination – Teleprotection

menu are, however, still available.

Simplified Definition of the Ripple Control Frequency

In the calculation settings for Harmonics/Ripple Control, the section on Ripple Control has a new

option to simplify the calculations of the network with diverse ripple control frequencies.

When the Use Frequency always from Calculation Settings option is switched ON, the ripple

control frequency indicated in this tab in the field Ripple Control Frequency is always used.

Otherwise the frequency defined in the basic data of the network level is used.

Coupled Multiple Lines

Editing coupled multiple lines with LEIKA has been improved.


Release Information

April 2013 16/33

Illustration: Dialog box for with coupling data

When you start LEIKA directly from the dialog box by clicking the button to edit the data, then when

you close the dialog box PSS SINCAL automatically generates all the required export files.

In addition, in connection with the new 4-wire load flow, couplings with ground cables/return

conductors are also possible.

Excel Import of Breakers

Breakers can now also be imported with Excel Import. The element name of the line and the node

name are used to assign breakers in the Excel table. In this way, the corresponding terminal where

the breaker should be placed can be uniquely identified.

Importing PSS U Data

This new import function facilitates the transfer of old PSS ADEPT data in the PSS U format.

Importing PSS U data (.dat) is a new feature available alongside the already existing HUB import.

File – Import – HUB File in the menu starts the wizard to import a file in PSS U format. If a DAT file

is selected, the new import function starts. Importing is still the same for HUB and DMP files.

The implementation of the new import function is based on the documentation "PSS/ADEPT-5.2",

section B.1 "PSS/U Data File Format".

In PSS U format also contains rudimentary graphic information about the positions of nodes/busbars.

This graphic information is also used, but the quality of the networks generated in this way is not

nearly as good as that of HUB files.

For lines in PSS U, TYP data from a construction file can be used. The same functions as for

importing with HUB are available. If the network was assigned a local standard type database for

importing, it tries to assign the appropriate standard types based on the name of the lines.


Release Information

April 2013 17/33

2.3 Pipe Networks

New Result Diagrams for Time Series

The result diagrams for time series calculations in pipe networks have been designed analogous to

that of the load profile calculations in electrical networks. All the results available for a period of time

are prepared as signals to be combined any way you want in the diagrams.

Illustration: New result diagrams for time series

The above illustration shows the new result diagrams. The different signals are combined in one

illustration. The flow at different kinds of elements is displayed as well as the water level of the water

tower.

In the course of the new time series calculations, the present view date from the calculation settings

is used. The preset date is used to design the network for the time series calculations and the

shutdown and installation of network elements are correctly considered. To make it easier to assign

results, the new diagrams also display the dates next to the times.

Enhanced Control of the Scope of the Results for Time Series

Time series calculations in large networks conducted over a longer period of time can generate very

large amounts of results. Normally not each individual result at each node point and at each line

section is of interest. For this reason, PSS SINCAL now offers the possibility of reducing the scope of

the results for pipe networks manually. This is done by marking the nodes and network elements.

After a specific configuration in the calculation settings, only result diagrams for marked elements are

provided. The definition for diagrams is done in the basic data with the attribute Diagram Creation,

and the definition for the geo-stationary calculations with the attribute Store Results.


Release Information

April 2013 18/33

Illustration: Reducing the scope of the results

To control the Storage of the Results, PSS SINCAL has the following options:

None:

With this option, no results are stored.

Completely:

All results are stored in the database.

Violations:

Only results for network elements exceeding the limits are stored.

All elements in case of violations:

If the limits are exceeded, the results for the entire network are stored.

Marked:

Only results for marked nodes and elements are stored.

Marked or violations:

PSS SINCAL saves results for marked nodes and elements, and for nodes and for elements with

violations.

The control for Creating the Diagrams works analogous to the results. PSS SINCAL has the

following options:

None:

With this option, no diagrams are generated.

Completely:

Diagrams are generated for all nodes and network elements.

Marked:

Only diagrams for the marked nodes and elements are stored.


Release Information

April 2013 19/33

2.4 Master Database

Improved Change Log

In the Master Database View, an administrator can evaluate all changes resulting from the publishing

of a user in detail. All the tables containing changes are listed. In each table, the modified attributes

of the records are displayed. Up until now, the records were only listed with the primary key. This is

mainly a problem in case of derived records (e.g. graphic data or element data), as it is not easy to

ascertain which node or which network element was modified.

To solve this problem, an enhanced name-mapping has been implemented in the overview of the

changes of the master database, which displays the appropriate name for all the records assigned to

a node or a network element.

Illustration: Overview of changes in Master Database View

The illustration shows the new Task Information in Master Database View. As can be seen in the

illustration, along with the respective modified records the names of the superordinate nodes or

network elements are also displayed.

For records without superordinate nodes or network elements, the name field of the record is

displayed, assuming it exists.

Publications Refused by the Administrator

This function lets an administrator refuse something published by a user. This gives publications a

special status. This means it still exists, but is not applied. Changes are refused directly in the Master

Database View.


Release Information

April 2013 20/33

There is a new icon in the Actions for refusing a publication. When the administrator refuses

something he can also add a comment. This is then stored in the Master Database and the users can

see why their publication was refused.

For refused publications, an option is provided to change the status to Publish again. In this way, for

example, an administrator can, after consulting with the user, still carry out a number of changes and

make these available for all other users with Publish All.

Improved Display of Tasks in the History

For a better overview of the different tasks in the history, these now have a symbol. This makes it

easier to identify the type of the respective task.

Illustration: History in Master Database

Preview of Changes for the User

This new function lets a user call up an overview of all the changes in the master database since the

last refresh. The changes are then visualized in a special HTML dialog box displaying all the new

publications. If an administrator has refused a user’s publication, this is displayed as well. This

means the user can see what the present state is even before the synchronization with the Master

Database is done using Refresh.


Release Information

April 2013 21/33

2.5 Reports

Improved Integration of the Reports in the User Interface

The integration of List & Label in the PSS SINCAL GUI has been improved. The display of the

reports is now done in the page layout analogous for the network diagram and the diagrams.

Illustration: Reports in PSS SINCAL

A search function is available in the integrated toolbar of the report window, and there is an

integrated scrollbar to customize the zoom level.

Another new feature is the possibility of exporting the displayed report in Excel format to allow

additional processing of the data with other applications. In addition to the XLS export format, the

formats PDF, XPS, EMF, XML and CSV are supported.

Implementation of List & Label 18

The new version 18 of List & Label is available in the new PSS SINCAL. The speed of the new

version for outputting large reports has been improved, and editing individual reports is now even

more intuitive.

With Windows 7, the designer has a multifunction bar (ribbon) for making the editing of reports even

more user-friendly.

Another practical feature is the improved Preview in the Designer for editing the report. The complete

structure of the report with all the groups is displayed in a way that is identical to the printed version.


Release Information

April 2013 22/33

3 PSS NETOMAC

3.1 User Interface

New Wizard for Creating Projects

To generate projects, PSS SINCAL has a new Wizard. This is used to create a new project with the

help of a template, but also generate a project with the help of an existing .net file.

Illustration: Wizard for creating projects

The function for creating new projects from an existing .net file makes it possible to adapt data from

older NETOMAC versions to the new project structure easily. The existing files are not modified;

instead a project file is generated that embeds the data correctly.

Improvements in the Diagram System

A number of improvements to the diagram system have been implemented to structure the

evaluation and documentation of results even more simply.

The new postprocessing function for converting signals can perform an RMS convert. This

should improve the evaluation and signal display in the EMS simulation. During the dynamics

simulation there is, of course, a function to facilitate the output of the space vector. This works,

however, only in symmetrical networks and needs to recalculate each time you switch between the

different types of displays. With the new postprocessing function, the conversion is done just before

displaying the signals in the diagram.


Release Information

April 2013 23/33

Illustration: Post Processing of signals

To better visualize signal values in the diagrams, there is the new Signal Position. This works

similar to the signal cursor in the old NETOMAC. Labels indicating the current signal value are

displayed directly at each signal in the diagram.

The labels can be moved in the diagram and a dialog box for placing the labels in a certain position is

also available. In the diagram, simply open the pop-up menu and switch ON the menu item Set

Signal Position.

Automatic Display of the Tabular View after Calculations

It is now possible to automatically open the tabular view after the calculation procedure. The

configuration is done under Editors and Views – Tabular View with the Options dialog box. There

you can determine whether the table should automatically open upon successful completion of the

calculations.

3.2 Calculation Methods

GUI Interactions with Calculation Methods

Some calculation methods, postprocessing functions and tools from PSS NETOMAC enable the user

to intervene interactively in the calculation process. For these interactions, there is the new

Simulation tool window. This window can display dynamic control elements and even information

during the calculations.


Release Information

April 2013 24/33

A typical example for the interactions with the user is the ASM identification, which runs in the dialog

mode. When you start the identification, the tool window for Simulation opens and you can select

the desired identification method. The calculations wait in the background until a selection is made.

Then the actual identification is performed.

Illustration: Starting the ASM identification

Depending on identification results, additional interactions are executed with the user to, for example,

improve the achieved results even more. At the end of the identification process, the complete result

diagram containing the results in the diagram as well as the identified parameters is automatically

generated.

Controller Debug

The Controller Debug is required to check that controllers are functioning properly. Debugging is

done here in the course of initializing the controllers. Each controller in the network can run step by

step interactively and the inlets and outlets of the blocks are visualized.

The calculation settings activate the Controller Debug. Controller Initial Conditions in the Output

tab switches ON the debugging. The interactive GUI of the calculation methods is displayed once the

dynamics simulation starts.


Release Information

April 2013 25/33

Illustration: Controller Debug in the GUI

In the GUI, the desired controller can be selected. After the selection is made, the source code of the

controller is displayed. In this source code, analogous to in Visual studio, break points can be set.

The current command in the controller is also visualized. The current inlet and outlet values of the

block are displayed directly behind the controller source code.

With the interactive GUI you can control the debugging of the controller interactively. The debugging

works similar to debugging in Visual studio. At each step or when a break point is reached, the GUI is

updated and the current status of the controller is visualized in the text editor. All possible control

options for debugging are available in the interactive GUI, and these adapt to the current context.

This means that if, for example, debugging of a controller is finished, a new controller can be

selected in the interactive GUI.

Passive and Active Frequency Response

The functions for calculating passive and active frequency response are now also integrated in the

user interface. The control settings for both calculation methods can be defined in the dialog box

Calculation Settings. PSS SINCAL has separate tabs for both active and passive frequency

response, where all control settings can be defined.

Calculate – Frequency Response Active or Calculate – Frequency Response Passive in the

menu starts the calculations.

The results of the calculations are stored in a binary frequency response file (.fre file). This contains

all recorded signals and is used to visualize the data in the diagrams.

To display the data in the diagrams, PSS SINCAL has a dialog box that can be opened in the

Diagram Page from Frequency Response menu. This dialog box can be used to generate

predefined diagram pages from a frequency response output file. First select the desired frequency

response output file in the dialog box. All the signals contained in the file are listed in the dialog box.

An unique feature is that each signal can refer to another signal. For this reason, the dialog box has

two lists of signals: Y1 (f) and YBase(f).

In the Y1 (f) list, select which signal should be displayed. YBase (f) defines the signal that refers to

Y1 (f). For the displayed Y value, the following applies:

)f(YBase

)f(1Y)f(Y

In the diagram on the left, the amplitude and the angle of the value to be displayed are always

displayed with the frequency. On the right, either a locus curve (imaginary part over real part) or real

part over frequency and imaginary part over frequency can be displayed. The configuration is done in

the section on Diagram Options of the Frequency Response dialog box.

3.3 Postprocessing and Tools

Flicker Evaluations

Flicker is the subjective impression of changes in brightness that are normally produced by

fluctuations in the supply voltage. The Flicker Evaluation assesses these fluctuations. The Flicker

evaluation is a postprocessing function performed following a dynamics simulation. The signals

recorded during the course of the dynamics simulation are evaluated with predefined functions to

determine the Flicker disturbance level.

The Flicker evaluation is started in the menu Postprocessing – Flicker. This opens a dialog box

where a Result file from a previous dynamics simulation can be selected.


Release Information

Illustration: Dialog box for Flicker

All the signals contained in this results file are displayed in the Signals list. From this list, select the

signals for which a Flicker evaluation should be performed.

Flicker Options controls the evaluation. A time frame for the evaluation can be defined and the

evaluation method can be selected:

UIE/IEC measurement method

IEC 61000-4-15

The Flicker evaluation generates a special FLI file. This is a binary results file that contains the output

signals and the corresponding Flicker evaluations. Diagrams can be generated from these FLI file.

The following illustration shows a typical result diagram of the Flicker evaluation.


Release Information

In the diagram above, the source signal is displayed using the time and directly below, the current

Flicker level. In the two diagrams below, the Flicker disturbance level is displayed as an absolute

value and as a sum. The significant settings for the Flicker evaluation are listed at the top right in the

diagram.

Eigenvalue Screening

Eigenvalue Screening enables a simplified and, more importantly, a quick evaluation of the

Eigenvalues without having to carry out complex and time-consuming calculations.

Postprocessing – Eigenvalue Screening in the menu starts the postprocessing function for

Eigenvalue Screening.

The results of the Eigenvalue Screening are prepared as an XRES results file which can be

displayed in Tabular View.


Release Information

The Eigenfrequencies/Residues table contains the current results of the Eigenvalue Screening.

The reference results of the Eigenvalue Screening are displayed in the Eigenfrequencies/Residues

Basis table. The Comparison table compares both the results.

Creating a Measure Data File

Measure data files are needed for identification, ASM identification and for dynamic network

reduction. These contain recorded signals from the dynamics simulation or entered characteristic

curves that serve as reference values in the identification.

The process of creating a measure data file is started with Tools – Measure Data in the menu.

Illustration: Dialog box for Measure Data

The dialog box has three options:

Calculation results from:

Here you can select between the result files for dynamics, frequency response passive and

frequency response active. The relevant calculations are performed and a measure data file is

created with the results.

ASCII file s-m-w:

Is required for the ASM identification.

Here you can select an ASCII file in the format s-m-w (slip-moment-weighting).


Release Information

April 2013 30/33

ASCII file t-y:

Here you can select an ASCII file in the format t-y, from which a measure data file is generated.

Identification

Identification adapts network sizes and characteristics with freely selectable settings to original

system sizes or networks (measurement values).

The prerequisites for performing identification are relatively simple:

A measure data file has to exist for the identification. It contains the reference values.

The calculation settings for the identification have to be defined. The variable to be identified and

the settings to be varied are defined here.

The identification is started in the Tools – Identification menu. The identification runs interactively in

the dialog mode. The Help Window for Simulation displays the control options. A diagram containing

the reference values from the measure data file, the initial values and the present identification

results is also displayed.

Illustration: Interactive control of the Identification

The sample project "Identify" with which the steps of the identification can be reproduced is also

contained in the setup.

ASM Identification

The ASM Identification is a special function in the area of identification. The speed of the machine in

the start-up characteristics are used for this. Based on the characteristic curve, the appropriate

settings for the equivalent circuit diagram of the machine are determined.


Release Information

April 2013 31/33

Illustration: Start-up characteristics of an ASM and equivalent circuit diagram

To perform an ASM identification, a special .net file that contains the machine to be identified is

required. The start-up characteristics of the machine are also needed. This is prepared in a simple

ASCII file in the format s-T-w (s: slip, T: torque, w: weight).

Tools – Measure Data converts the file into a binary measurement file (.mes).

The actual identification can be started in the menu Tools – ASM Identification. This then runs as in

dialog mode. The Simulation window has a variety of control options, and the results of the

identification are visualized. The start-up characteristics are displayed according to the measure data

file, according to the start parameters and finally according to the identification. This makes it easy to

evaluate whether the results achieved already meet the specifications. The control options can be

used to continue the optimization until the results you want are attained.

At the end of the identification, the diagram is updated and the machine’s identified parameters and

enhanced characteristics are displayed.

In addition, the LOG file contains both the identification results and the appropriate block of data for

the identified machine. This block of data can then simply be added to a .net file.
