    • Version 18 is a version with many, many, many small changes throughout

    • Concentration this past year has been on improving existing features – Contingency Analysis had a good number – PV Curve ramping change – Improved RAS handling for linearized contingency – Extensive work on stability tool

    What’s New in Version 18

  • 3 © 2014 PowerWorld Corporation

    • Multi-section lines: special SUBDATA section “BusRenumber” to help renumber dummy buses

    • When loading an auxiliary file with object types REMOVEDBUS, REMOVEDBRANCH, etc.. The corresponding objects can be deleted. (objects seen on the Topological Differences dialog)

    • Ability to read write REVERSE bids for StudyMWTransactions

    Auxiliary File Improvements

  • 4 © 2014 PowerWorld Corporation

    • Difference Flows Improvements – When in Difference Flows mode, switched shunt Min Mvar,

    Max Mvar, Shunts Blocks, and Shunt Steps will now show differences between the Present and Base case

    – Custom Floats and Integers now show differences in Difference Flows

    • When using the option to display column headers as variable names, the upper left cell in case information displays will now show the objectname of the objects in the table.

    • New Generator field: Mvar Capability Curve Is Defined – Indicates if the generator has a curve and not if the curve

    should be used (already have a “Use Capability Curve”)

    Case Information Displays

  • 5 © 2014 PowerWorld Corporation

    • New Branch Fields for limits in Amps instead of MVA – Allow you to edit line limits in Amps

    instead of MVA. – This only works for non-transformer

    branches. – We only store one set of limit, so this

    only allows you to edit those limits in different units

    • Change Limit A Amps automatically changes Limit A MVA too

    Case Information Displays

  • 6 © 2014 PowerWorld Corporation

    • Changed Model Condition and Model Expressions references to objects – Previously we used a silly XML-inspired string – Specify object references using a simple string "ObjectName

    ' Key1' ' Key2'" – Gen11A Gen '11' 'A‘

    • Generally removed use of old format throughout – When reading old AUX files these still will read in fine – We no longer write out AUX files in this older format

    Auxiliary File Cleanup

  • 7 © 2014 PowerWorld Corporation

    • Previously the “CTG_Option” object allowed editing options in AUX or Case Info

    • New object “CTG_Option_Value” allows same but it’s “vectorized” – Grouped – Better description

    New “Option_Value” objects for editing options in AUX or Case Info

  • 8 © 2014 PowerWorld Corporation

    • Many of them have been done

    Options by Value

  • 9 © 2014 PowerWorld Corporation

    • Cleans up editing existing objects by allow a field that interprets ALL various key filed choices – Looks for Primary Keys – Looks for Secondary Keys – Looks for Labels

    • Can not CREATE objects using this field, but great for editting existing objects – Simplifies AUX formats such as for contingency analysis

    New Field “ObjectID”

    Gen (ObjectID, CTGPreventAGC, CTGPartFact, CTGMaxResp, UseLineDrop, Xcomp) { "Gen 'Texan_69.0' '1'" "NO" same 22.0 "NO" 0.0001 "Gen 'Viking_345' '1'" "YES" 54.0 "11%" "NO" 0.0123 "Gen 'Viking_345' '2'" "RESPOND" same 5.0 "PostCTG" -0.0500 "Gen 'Jet_69.0' '1'" "YES" 88.0 "" "PostCTG" 0.0512 "Gen 77 '1'" "RESPOND" same 0.0 "NO" 0.0001 "Gen 55 '1'" "NO" same "" "NO" 0.0001 }

  • 10 © 2014 PowerWorld Corporation

    Visual Indication of ObjectID and Label

  • 11 © 2014 PowerWorld Corporation

    • Quick Filter is available when choosing an object

    • Increase width of file name list in recently opened files

    User Interface Enhancements

  • 12 © 2014 PowerWorld Corporation

    • Numeric edit boxes with arrows will now automatically increase the number of decimal places to ensure that at least 2 significant digits are visible

    • Transient Stability model parameters in case info displays no longer obey the “decimal places” user option. Now simplay always shows 7 significant digits while removing trailing zeros

    User Interface Enhancements: Maintaining Significant Digits

  • 13 © 2014 PowerWorld Corporation

    • SetInterfaceLimitToMonitoredElementLimitSum(filtername)

    • RenumberBuses, RenumberAreas, RenumberZones, RenumberSubs – each have parameter denoting custom integer to use

    • CTGRelinkUnlinkedElements • TSResultStorageSetAll • CTGJoinActiveCTGs • DiffFlowRefresh – resets topological links between

    for difference flows

    New Script Commands

  • 14 © 2014 PowerWorld Corporation

    • Loads a CSV file as though it’s an AUX file if it was created by saving the file by choosing Save As\CSV or by Sending to Excel and then saving as CSV

    New Script Command: LoadCSV("filename", YES)

  • 15 © 2014 PowerWorld Corporation

    • Needed by ISO-New England to better handle exported State Estimation cases with unobservable pockets

    ConditionVoltagePockets (VoltageThresh, AngleThres, Filter)

  • 16 © 2014 PowerWorld Corporation

    • Added ability to use the keyword ALL in special places to specify a list of variable names – Multiple Element TLR: MultBusTLRSense:ALL – Multiple Direction PTDF: LinePTDFMult:ALL

    • With script commands SaveData(), SaveDataWithExtra(), SaveObjectFields() and SendToExcel(), you can now specify All in the list of fields and it will do ALL available fields the objecttype

    • Allow special keywords @DATETIME, @DATE, @TIME, @BUILDDATE, and @VERSION to be used as part of the filename for SaveDataUsingExportFormat, SaveData, SaveDataWithExtra, SaveObjectFields, and WriteToTextFile script commands. These special keywords will be replaced with their actual values when the file is saved.

    Script Command Modifications

  • 17 © 2014 PowerWorld Corporation

    • Within all script commands related to opening or saving files, added a new ability to specify a filename of a special form that instructs PowerWorld to bring up the Open or Save dialog for the user to choose a file. – Syntax of the file name is generally "“ – The entire string must start with – Followed by a space and then a caption to be placed at the top of the

    file dialog – Followed by an optionally list of File Types and extensions specified

    • Enclosed in single quotes. • List itself is composed of a pipe-delimited string (|) with the first string

    representing the first file type, the second string representing the first file extension, the third string represent the second file type, the fourth string representing the second file extension and so on.

    • Assume 'All Files (*.*)|*.*' if omitted –

    Using a script command to bring up the Open or Save Dialog

  • 18 © 2014 PowerWorld Corporation

    • Scale() script command – allows specifying the new value or scale factor through a field with the object

    type to scale. – To use this option, the [parameters] input should contain variablenames instead

    of numeric values. – When using a field rather than value, the scaling will be done by individual

    object rather than the aggregation of all objects selected for scaling. • SendToExcel script command

    – will now allow the saving of .xlsm filetype if using Excel 2007 or later. • DetermineBranchesThatCreateIslands script command

    – Now allows you to enter a blank for the filename. If the filename is blank, the selected field will be set for lines that create islands regardless of how you have that option set

    • CloseWithBreakers() script command – Now allows you to specify a single object instead of a objecttype and filter.

    CloseWithBreakers(Gen, [1 "1"], YES);

    Script Command Modifications

  • 19 © 2014 PowerWorld Corporation

    • New Iteratively Found strings possible because of a new contingency action “Abort” – CTG_ABORTED_LINEAR, CTG_ABORTED_AFTER_LINEAR,

    CTG_ABORTED_IN_FULL, CTG_ABORTED_ITERATED • Injection Group Iteration options

    – Generator Economic Merit Order Dispatch can now be used • When generator MW limits are being enforced, the linear

    calculations used as part of the iterated solution methods will not include generators that are already at their limits

    • Allow Generator MW Limit Enforcement in Single Linear Step option added to not include generators that are already at their limits when using the Single Linear Step Method – For generators to be excluded, appropriate options to enforce

    generator MW limits must also be set

    Available Transfer Capability Tool (ATC)

  • 20 © 2014 PowerWorld Corporation

    • Previously, when using linear methods, all actions which were POSTCHECK or TOPOLOGYCHECK were treated as CHECK and evaluated only in the reference state

    • This will more accurately model conditional actions when using the linear methods by adding some iteration to the linear analysis and estimate if the POSTCHECK or TOPOLOGYCHECK actions would be triggered – Used by linearized contingency analysis – Used in the ATC tool

    • Conditional Actions which monitor the following fields – Branch: Status, Derived Status, Online, Derived Online, Amps,

    MW, Limit Monitor % – Interface MW – Note: We will add more if feasible and requested

    Handling RAS in Linearized Contingency Analysis (and ATC)

  • 21 © 2014 PowerWorld Corporation

    • Interface – FGMW, MW\MW Flow

    • Branch – BusObjectOnline, Online – BusObjectOnline:1, Derived Online – DerivedStatus, Derived Status – LineStatus, Status

    – LineAmp, Amps\Amps at From Bus – LineAmp:1, Amps\Amps at To Bus – LineMaxActAmp, Amps\Amps (maximum)

    – LineLimitPercent, Limit Monitoring\% at From Bus – LineLimitPercent:1, Limit Monitoring\% at To Bus – LineLimitPercent:2, Limit Monitoring\% Used

    – LineMW, MW\MW at From Bus – LineMW:1, MW\MW at To Bus – LineMaxMW, MW\MW (maximum)

    List of fields that are handled for iterated linear contingency analysis

  • 22 © 2014 PowerWorld Corporation

    • Under Records on the list of Contingencies, you can choose Verify Contingencies for Iterated Linear Actions

    • This writes out a text file summary indicating which of your RAS Model Conditions that are supported for linear methods.

    Handling RAS in Linearized Contingency Analysis (and ATC)

  • 23 © 2014 PowerWorld Corporation

    • Added new contingency generator actions to Set To or Change By Mvar. When this action is used the generator will be turned off AVR.

    • Added Line Shunt contingency actions. Line shunts can be either opened or closed.

    • Abort Action – This is a special contingency action which will cause the

    contingency process to abort and report “Abort” as the reason

    – Requested so that if the system state reaches a situation that is not allowed (defined by Model Condition or Filter) then contingency aborts

    – Example: Alberta separation into island

    New Contingency Actions

  • 24 © 2014 PowerWorld Corporation

    • Previously it was either YES or NO, but now there are two more choices

    • ABORTED – Contingency that has been aborted due

    to an Abort contingency action being implemented

    • RESERVE LIMITS – Indicates that there was not enough MW

    reserves in the make-up power specification to cover the MW changes caused by the contingency. Thus some make-up power ends us sent to the island slack bus

    – Field Results\Make Up Power Deficit MW will tell you how short of MWs you are

    Contingency SOLVED Field

    HINT

  • 25 © 2014 PowerWorld Corporation

    • Remedial Action has the following – Name – Skip field – List of contingency elements

    • In practice these are similar to the existing Contingency Global Actions, however, they permit – Grouping actions into a “named RAS” – Ability to disable the RAS by setting

    the Skip field

    New Contingency Container: Remedial Action

  • 26 © 2014 PowerWorld Corporation

    • Added insertion of multi-section line dialog • Added more options to the Join Active

    Contingencies tool: – (1) Join the active list to itself – (2) insert solve power flow action between

    contingencies that are being joined – (3) delete existing contingencies.

    • (*.OTG) format contingency files can now be loaded into contingency definitions.

    Defining Contingency Actions

  • 27 © 2014 PowerWorld Corporation

    • Auto-insert – Auto insert switched shunt outages – Auto insert 3-winding transformers

    • Now have options on how to treat 2-winding and 3-winding transformers.

    – Added filtering by nominal voltage kV – Enhanced the ability to auto insert based on the

    distance from a particular bus using the features available from the Connections\Determine Path Distances to Buses on the tools menu of Simulator.

    Contingency Analysis Tool

  • 28 © 2014 PowerWorld Corporation

    Auto-Insert Contingencies

  • 29 © 2014 PowerWorld Corporation

    • Global Actions that are skipped will no longer be reported in What Actually Occurred. – Same goes for new Remedial Action Elements

    • Improved the descriptions in the popup hints shown with options on the contingency analysis dialog.

    • Contingency Result field: “Total Generation Drop” – Shows the total amount of generation change for any

    reason including islanded gen, gen opened from a gen or injection group action, and gen dropped from injection group merit order open action.

    Miscellaneous Contingency Features

  • 30 © 2014 PowerWorld Corporation

    • Contingency and Custom Monitor Categories – Categories determine which custom

    monitors are active for a contingency – For a monitor if no categories are

    specified, the monitor will be active for all contingencies

    – For a contingency if no categories are specified, all monitors will be active for the contingency.

    – Otherwise, a monitor will only be active for a contingency if it has at least on category that matches one of the contingency's categories.

    Contingency and Custom Monitor Categories

  • 31 © 2014 PowerWorld Corporation

    • This option will compare the presently defined contingency list against an AUX file (which contains another set of contingency definitions)

    • The output will be a CSV file that lists contingencies that match one another

    • Comparison only compares the actions in each contingency definitions – Does not compare the model

    criteria or actions status, thus it may report two contingencies as the "same" even though the conditional checks make them function slightly differently.

    Contingency Analysis: Compare Condition Definitions

  • 32 © 2014 PowerWorld Corporation

    • Various transient relays can now be automatically handled in power flow contingency analysis

    • Treatment is specified by model type – TIOCRS, LOCT1, TIOCR1, MSC1 – Choices are Monitor, Trip, or Ignore

    • Default is to ignore – Also, if Transient Model Status = Inactive then ignore

    • These have been implemented very generically inside PowerWorld Simulator – Future: Generator Relays, Load Relays, Load Model

    with embedded tripping, under voltage motor tripping – Other?

    Treatment of Transient Stability Models in Power Flow Contingencies

  • 33 © 2014 PowerWorld Corporation

    • Ignore – default setting

    • Trip/Act – if conditions of model are met

    then actual actions will be taken (such as tripping a line for overcurrent)

    – If “monitor only” flag of stability model, then the specific model will instead just monitor

    • Monitor Only – if conditions of model are

    met, then special contingency limit violations are reported

    – Similar to “Custom Monitors”, but they will show up as “Transient” monitors in the contingency analysis results

    Options for Treatment in Power Flow Contingency Analysis

  • 34 © 2014 PowerWorld Corporation

    • Separate Presentation Later

    Transient Models in Power Flow Contingency

  • 35 © 2014 PowerWorld Corporation

    • EPC file – When writing out an EPC file and the Ohmic Data Flag field is 1, R and X will be

    written in ohms and B in microMhos – Saving a removed multi-section line in the EPC format should correctly write the

    sections of the multi-section line with a status of -4. GE flagged for delete flag for multi-section line will be true if any section is flagged for delete.

    • RAW file – When loading a RAW file, we now automatically flag any non-transformer

    branch with R=0, B=0, and X

  • 36 © 2014 PowerWorld Corporation

    • When defining expressions for objects, a new option has been added to treat blank entries as zeros in the expression instead of treating the entire expression as invalid.

    • The bus nominal voltage field can now be compared between the present and base case using Difference Flows features

    • When using the tool to renumber multi-section line dummy buses, either through the GUI or script, a new bus that does not exist no longer needs to have a bus name specified. By default the bus name will be the same as the bus number.

    General

  • 37 © 2014 PowerWorld Corporation

    • Injection groups now have their own set of options that define how they should be scaled – These override settings in tools that now allow use of

    injection group-specific options are PV, ATC, Island-Based AGC, Injection Group Area Slack, Time Step Simulation, and Scaling.

    • Injection Group can now contain buses – Only used for sensitivity tools (TLR, PTDF) and

    Weighted average calculations (Marginal Costs) – Not used when an actually change in MW injection at

    generators and loads is required. Bus points are just ignored then.

    General

  • 38 © 2014 PowerWorld Corporation

    • Added support for handling Wye-Delta-Delta connected transformers

    • Added GIC transformer fields to show if terminal buses are in different substations

    • Added GIC fields to show the driving point resistance calculation at a substation. This helps in determining the sensitivity of the GIC currents to a change in the substation grounding resistance.

    • The Transformer Per Phase Effective GIC field now works with the Difference Flows features.

    • Added a "Validate Input Data for GIC" button on the GIC dialog. Presently, this only checks if any lines are longer than 776.5 miles (1/4 wavelength).

    Geomagnetic Induced Currents

  • 39 © 2014 PowerWorld Corporation

    • Added the ability to edit a special record called the Unified Transformer in the GIC dialog – This record provides one place to edit all the GIC-

    related inputs for both two-winding and three-winding transformers so that you do not have to navigate through the internals of the three-winding transformer model or the various ambiguities introduced by auto-transformers

    Unified Transformer in the GIC dialog

  • 40 © 2014 PowerWorld Corporation

    • Added ability to import KML files in the format used by MISO. The lines will link to lines in the RAW file, if they exist. There are no substations in the RAW file, so it will create them (but they will be empty) if desired.

    • Modified some size thresholds at which labels appear when exporting to the KML file.

    • KML importer now has the ability to import KML files in the specific format that ERCOT uses.

    Oneline Features More KML Support

  • 41 © 2014 PowerWorld Corporation

    • Added ability to link to a bus view or substation view from a Oneline Link. – Populate the File or Action string with the keyword

    BUSVIEW or SUBVIEW along with the number, name_kv, or label of the bus or substation that should open in the appropriate view.

    • Added Find Text in Oneline Tool

    Oneline Features

  • 42 © 2014 PowerWorld Corporation

    • Modified the flat start routine when applied to a system which contains many 30 degree phase shifts related to Delta-Wye transformer connections. The new flat start routine will set voltage angles in a manner that handles these phase shifts.

    • Added error checking for parallel transformers so that if they do not regulate the same bus (actually ZBR Bus group), then the transformer will be turned off control automatically and an appropriate message written to the log

    • Added a power flow solution option to disable SVCs independently of other switched shunts. – The area option for shunt control only applies to non-SVCs. – SVCs can only be enabled/disabled globally or at the individual

    device level.

    Power Flow Solution

  • 43 © 2014 PowerWorld Corporation

    • 'Aborted Contingency' is a new PV critical reason if a contingency fails to solve because an Abort action has been implemented

    • Added a new feature on the PV curve to treat a negative dV/dQ value at a bus for which this quantity is tracked as a critical scenario (treated the same as a failed power flow solution)

    • Added option to open Bus View for an object associated with a data series on the PV plots the same as you could already do with the transient stability plots

    • Added ability to have PV plotting based on actual value, deviation, percent of the initial value, or percent deviation from the initial value.

    PV and QV Curve (PVQV) Tool

  • 44 © 2014 PowerWorld Corporation

    • Injection Group Source/Sink (what we’ve had) – Specify a Source and Sink injection group. Source

    injection goes up and sink absorbs the change – Performing the MW Ramping (increasing the “Nominal

    Shift”) represents injection at the Source • Interface MW Flow (Specify Interface X)

    – You must have the OPF add-on tool to use this – Configure your OPF controls to determine what is

    allowed to move expectation is folks will use the minimum control change, but you could use economic costs too

    – Performing MW Ramping represents increasing the target MW flow on an interface

    PV Curve Ramping Method: Interface MW Flow

  • 45 © 2014 PowerWorld Corporation

    • Specify Interface Y as another setting and then an angle as a search direction

    2D PV Interface MW Ramping

  • 46 © 2014 PowerWorld Corporation

    • Specify Interface Z as a third interface – While ramping out in the “X/Y” plane using the

    search direction add an additional constraint

    3D PV Interface MW Ramping

  • 47 © 2014 PowerWorld Corporation

    • ABORTED will be reported in the QV overview results if a contingency fails to solve because an Abort action has been implemented.

    • A new field with Buses called “QV Selected” is now used to determine for which buses QV curves are calculated during QV analysis. – Previously we used the “Selected” field which was

    confusing. The “Selected” is no longer used.

    QV Curve Tool

  • 48 © 2014 PowerWorld Corporation

    • Added a read only field "In Outage?" to various objects to indicate if the object is referenced by a current Scheduled Action.

    • Added ability to use a "Scheduled Action" filter on a case information display showing a list of "Scheduled Action Groups".

    Scheduled Actions

  • 49 © 2014 PowerWorld Corporation

    • New SimAuto Functions – GetSpecificFieldList – GetSpecifiedFieldMaxNum – New OpenCaseType(FileName, FileType, Options)

    function. • This function behaves the same way that the OpenCase

    script command works with FileType and Options being the same as those specified with the script command. The Options parameter is optional

    Simulator Automation Server (SimAuto)

  • 50 © 2014 PowerWorld Corporation

    • Added ability in TSGetResults() script command to use a file type of "JSIS" which will write out desired results in a format used by the WECC JSIS group.

    • Added ability in the Plot portion of the transient stability dialog to export the plot information to a text file of the format used in the TSGetResults() script command. Also added ability to export in the JSIS format in the same location.

    • Continuing support for reading (*.SWT) switch files including DB (Delete bus), MBL (modify bus load), and RL (reinstate lines)

    • Added a local menu option to Time Shift Contingency Elements which shifts all elements by a specified number of seconds

    Transient Stability

  • 51 © 2014 PowerWorld Corporation

    • Added ability to use the special string @CTGEvents in transient stability plot definition strings. – This string will be replaced with a list strings showing

    the transient result event strings which are written to the message log during the simulation.

    • Added ability to have plotting based on actual value, deviation, percent of the initial value, or percent deviation from the initial value.

    • Added better log warnings when loading TSR files which don’t perfectly match the presently open case

    Transient Stability Plotting

  • 52 © 2014 PowerWorld Corporation

    • Added a list of Categories to both a Transient Contingency and Transient Limit Monitor – Categories determine which limit monitors are active for a

    contingency • For a monitor if no categories are specified, the monitor will be active

    for all contingencies • For a contingency if no categories are specified, all monitors will be

    active for the contingency. • Otherwise, a monitor will only be active for a contingency if it has at

    least on category that matches one of the contingency's categories. • Transient Stability Limit Monitor Violations

    – Added extra columns for area, zone, owner, substation, nominal kV, labels, bus numbers, names, circuit ids for respective violations

    – Same functionality has existing in power flow contingency analysis for many years.

    Transient Limit Monitors

  • 53 © 2014 PowerWorld Corporation

    • For induction motor models (CIM5, CIM6, CIMW) which specify inputs as circuit parameters (R1, X1, R2, X2) added error check for time constants which are too fast. Will auto-correct by increasing the R1 or R2 values.

    • Added validation check for stability models which are out-of-service but might be closed in during simulation – Gen models: MOTOR1, CIMTR1, CIMTR2 – Load models: CIM5 and CIM6

    • Checks to ensure SVC dynamic model Xc matches the power flow model Xc term (auto-correct changes to match power flow model)

    • Validation error for an active SVC dynamic model if the switched shunt is not marked as an SVC

    • Many many more we have likely forgotten about!

    Transient Model Validation Checks

  • 54 © 2014 PowerWorld Corporation

    • Generally improved solution when running faults near wind turbine terminals

    • Added new wind turbine models – REGC_A (machine) – REEC_A (exciter) – WTGT_A (governor) – WTGPT_A (stabilizer) – WTGAR_A (aerodynamic model) – WTGTRQ_A (PREF controller) – REPC_A (plant controller)

    • Line Relay Models – TIOCRS, LOCTI, TIOCR1, DistRelay – Various user interface options for showing % reach – LOADEN (load encroachment)

    • DC Transmission Line models – PDCI model was previously done – Intermountain DC line model has now been implemented

    New Stability Models: Separate Presentation Later

  • 55 © 2014 PowerWorld Corporation

    • For induction motor (loads) and induction machine (generators), whenever the speed drops below 0.1 per unit, then the integration time step will be automatically reduced that it is 20 times smaller at 0.0 per unit speed.

    Model Improvements

  • 56 © 2014 PowerWorld Corporation

    • When reading in a DYD or DYR file, we now set the option regarding how to treat saturation functions for which the magnitude of SE1 and SE2 are backwards to be consistent with how that feature is treated in the associate file format

    • Added new option for “Include undocumented PI limits”

    Transient Stability: File Formats

  • 57 © 2014 PowerWorld Corporation

    • Added new script commands – TSAutoCorrect – TSRunUntilSpecifiedTime(ContingencyName,

    [StopTime, StepSize, StepInCycles, ResetStartTime, NumberOfTimeStepsToDo]).

    Transient Stability: Script Commands

  • 58 © 2014 PowerWorld Corporation

    • Added ability on generator table to edit Rcomp, Xcomp, H on the system MVA Base. – This will modify Rcomp, Xcomp, and H setting from the internal stability

    model – Convenient because everything is normalized to system base

    Transient Stability: Dialogs

  • 59 © 2014 PowerWorld Corporation

    Transient Stability: Auto Insert Transient Contingencies

  • 60 © 2014 PowerWorld Corporation

    • Single Transmission Line – 2 contingencies created

    • At FaultLocation and (100 – FaultLocation) • Only one created if Fault Location between 49.5 and 50.5

    – Fault will occur at Event Time – OPENFROM will occur after Event Duration – OPENTO will occur after Event Duration

    • Single Bus – Fault occurs at Event Time – BUS OPEN (all branches connected to bus open) occurs after Event Duration

    • Single Transformer – 2 contingencies created

    • Fault at From End • Fault at To End

    – Fault will occur at Event Time – OPENFROM will occur after Event Duration – OPENTO will occur after Event Duration

    • Single Generator – Generator will open at Event Time

    Transient Stability: Auto Insert Transient Contingencies

  • 61 © 2014 PowerWorld Corporation

    • Scale using a field by Factor or Value

    • When using a field rather than value, the scaling will be done by individual object rather than the aggregation of all objects selected for scaling.

    System Scaling Enhancements

  • 62 © 2014 PowerWorld Corporation

    • Cleaned up header to replace “DATA” with the object name instead • No longer include the “CreateIfNotFound” field. It just always assumed YES for that • Utilize the ObjectID field a lot so we don’t need separate DATA sections • Improving the variable names to make more sense. • Presently, only used for “WECC Contingency” file
