Hi I want to create an islanded grid at my network which has 1 main source and 1 DG. I have read that i need a vsource to provide excitation and that in order to set up the Vsource i have to defince the angle, MVAsc1 and MVASC3, or the impedances. Ive searched the relevant topics but i havent manage to figure it out. First of all do i have to define the values of the Vsource based on the DG or the main supply? Also do i have to disconnect the existing DG? And most importantly i do not know how to...

Hi, Sorry for typing it wrong. I do use the dot on the code. So the question is if phasetrip accepts a variable from matlab. (Phasetrip=x)

Hi Davis, I have tried to change the setting of the phasetrip by giving a double variable or use num2str for a character array (Phasetrip=x) but it shows an error. Do you know if there is a way to do this or all we can do is for example Text.Command='Relay.Relay_BC Phasetrip=200';

Thank you Davis

Hi, i am working on the following network which is generation, line AB, lineBC. I apply a fault in bus A and at bus B i have a DG and at bus C a load. The relay is opening line AB but lineBC where i expected the DG to keep feeding the load does not seem to work as i get zero currents. Set DefaultBaseFrequency=50 ! delete this line if your default frequency is already 50 Hz clear !! new network new circuit.example basekv=132 pu=1.0 angle=0 frequency=50 phases=3 !! substation transformer new transformer.SS...

Hi , I am not sure if i understand what you mean by this. If you mean that i should place the while loop right after the faultstudy, i tried it and it does not work which makes sense as the dg and load won't change over time. Thanks

This is a part of the code cd 'C:\Users\diro\Desktop\DSS\33kv_case2' %#ok<MCCD> % Specify the Simulation Case casename = 'Case 1'; % for example %------------------------------------------------------------------------- %--------------------------- % Start OpenDSS %--------------------------- % Initiate the DSS Engine DSS = actxserver('OpenDSSEngine.DSS'); % Dimitrios - check 'actxserver' is still the correct syntax!!
