    I am inquiring following questions:

    [1] Can I set simulation options and run the simulation (including setting simulation configuaration) from Javascript in EMTP?

    [2] Can I link Javascript to Netlist file?

    Hi Manzur,

    [1] Can I set simulation options and run the simulation (including setting simulation configuaration) from Javascript in EMTP?

    Yes and it is quite easy. Here is a sample code that updates the simulation options :

      cct=currentCircuit();

      parseScriptFile(‘simoptions/object_creator.dwj’);

      parseScriptFile(‘simoptions/open.dwj’);

      parseScriptFile(‘simoptions/save.dwj’);

      //Create Object from current circuit

      oSimoptions = new oDevice_(cct)

      oSimoptions.LoadFlow          = 0;

      oSimoptions.StartFromLoadFlow = 0;

      oSimoptions.steadystate       = 0;

      oSimoptions.timedomain        = 1;

      oSimoptions.fscan             = 0;

      oSimoptions.Dt               = 10;

      oSimoptions.tmax             = 1000;

      oSimoptions.SaveData();

      

    You can find more examples here: http://emtp.com/site/file.php?id=59 .

     

    [2] Can I link Javascript to Netlist file?

    It is possible to run a netlist from a script by calling the method “”run_emtp””. You can look at the “”Parametric”” case of the EMTP-RV examples and to the associated documentation (parametric.pdf).

    Hello Emanuel,

    I am trying to learn how to use javascript to build circuit in emtp. I want to alter the parameters for a pi line 3 -phase. I was able to select the units, and sequence data for R, L and C. However, I am unable to change any values. This is what I am trying to do:

    dev1=cct.addDevice(DWLibrary(‘RLC branches.clf’).loadType(‘PI line 3-phase’),0,0,’s’)

    dev1.setAttribute(‘ParamsA’,’3,1M,1,1ohm,1,1uF,1,0,0,0,0,0,0′)

    array=SPArray(‘1 2 \n 3 4 \n 5 6 \n 0 0 0 \n 0 0 0 \n 0 0 0 \n’);

    dev1.setAttribute(‘ModelData’,array)                          

     

    I intend to put the sequence data therefore my array is ‘R0 R1 \n L0 L1 \n C0 C1 \n all 0’s for initial conditions’

    By what i see in the .ecf while when i open the pi line is this: R0=1 R1=2, L0=1 L0=2 C0=1 and C1=1

    and Initial condition matrix shown is

    1 4 0

    2 5 0

    3 6 0

     

    Can you please point out the mistake in this?

    Thanks in advance!
