Software for theElectrical MachinesLaboratoryDL 9330SW1AThis eTraining Package covers all the study subjects andthe experiment activities that are performed in a computercontrolled electrical machines laboratory.It works with the following types of machines:

Single-phaseandthree-phasetransformersDirect current machinesSynchronous machinesAsynchronous machines

It is divided in 2 sections, hereunder described:

Educational section:In this section we illustrate, through WEB pages, the testto be performed by providing all the information relevantto:

General diagram of the testInsertion of the instrumentsOperation modesQuantities to be acquired by the instruments and quan-tities to be calculatedCharacteristic graphs for the test

Operationsection:In this section we illustrate how the instruments must beconnected and how to start the program for controlling theexecution of the test.The above program provides:

aControl Window, that allows to insert the name of thestudent and the characteristic data of the machine;moreover, it contains the controls to operate during theautomatic and semi-automatic tests;a Window with the diagram of the measurement sys-tem, that contains the block diagram of the measure-ment system, with the indications of the quantities com-ing from the instruments, updated in real time;a Spreadsheet Window, that contains an electronicsheet where the values of the measurements taken dur-ing the execution of the tests are collected.once the test is competed, it is possible to open severalGraph Windows , where it is possible to visualize ingraphical form the data that have been gathered.

During the AUTOMATIC execution of the test the user con-trols the start of the test and the program automaticallyvaries the conditions of the system and acquires the inter-

esting quantities. In this case it is necessary to use aninterface module (DL 1893) and motor driven modulesthat are controlled through computer; it is also neces-sary, of course, to have digital measurement modulesfor the experiment data acquisition and transfer.

During the SEMI-AUTOMATIC execution of the test theuser manually sets up the value of the quantities of the sys-tem (through non motor driven power supplies, variac, etc.)and controls the acquisition of the interesting variablesthrough the program.

The software allows a complete graphic processing of theresults that have been obtained. It is possible to open at thesame time several different graphs.These graphs can be of two types: time graphs (showing thebehaviour with time of the interesting quantities) or XYtype graphs, where it is possible to select the quantities toshow in the X and Y axes.Moreover, the software allows to print all the data of the testfor what concerns: data of the student and of the machineunder test, data from the electronic spreadsheet, graphs.

Software for theElectrical MachinesVirtual LaboratoryDL EMVThis eTraining Package transforms the Computer to anElectrical Machines Laboratory, where it is possible to per-form all the educational activities which are related to thestudy and the experiments on the machines, without theneed to have any hardware: everything is virtually simulat-ed by PC.

It covers the following types of machines:Single-phase and three-phase transformersDirect current machinesSynchronous machinesAsynchronous machines

It is divided in 3 sections as follows:

Study:In the section relevant to the study of the electrical machi-nes the following subjects are illustrated by means of theInternet World Wide Web hypertextual technique:

their operating principletheir basic structuretheir characteristics

In this section multimedia tools (drawings, images, photos)and hypertextual techniques are widely used to illustrate thevarious components of the electrical machines and to provi-de, every time, the simplest path for the use of the informa-tion.

Design:In the section relevant to the design, we simulate, virtuallyby PC, the process of designing and manufacturing the elec-trical machine.Once inserted the main design parameters (e.g., rated4

power, rated current, frequency, etc.), the computer pro-ceeds step by step to dimensioning the machine. Drawingsof the electrical and mechanical details and cross-sectionsof the inside complete this section to illustrate in detail theconstruction process.All the data (set up parameters and calculated results) canbe saved in a personal file that forms an electrical machi-nes database.The data can then be used for the practical realization ofthe machines.For each machine it is necessary to input the design para-meters while the manufacturing parameters are conse-quently calculated. All these parameters are used for theperformance of the tests and for the actual realization ofthe electrical machine, if so required.

Operating tests:In the section relevant to the operating tests the programsimulates, on the computer, the performance of the typicaltests on the designed machine: no-load test, short-circuittest, load test, etc.This allows an immediate check on the design targets ofthe machine, without actually constructing the machine.In this phase the machine can be coupled to other machi-nes in the database (for instance, for the load test).Each test is complete with the relevant description thatillustrates the purpose of the test and the relevant opera-ting mode.During the execution of the test it is possible to check onthe monitor the values of the quantities which are acqui-red by means of virtual instrumentation and it is possibleto draw the typical graphs, by selecting the interestingquantities.
