2015-03-03 10:31:13 -0500 | asked a question | How to modulate the governor or exciter of generator in PSS/E for dynamic simulation? I am kind of new in PSS/E but here is my question: I have a single machine infinite-bus, how can I modulate the governor or exciter of machine with a sin wave when I am doing dynamic simulation? I found out that change_gref can change the value of the element of the GREF (governor reference). But I am not sure if I can use it to modulate the governor with sin wave. Here is my python script: psspy.newcase_2([0,1], 100.0, 60.0,"","") psspy.busdata3(1,[2,i,i,i],[f,f,f,f,f,f,f],_s) psspy.busdata3(101,[3,i,i,i],[f,f,f,f,f,f,f],_s) psspy.buschng3(1,[i,i,i,i],[ 100.0,f,f,f,f,f,f],_s) psspy.buschng3(101,[i,i,i,i],[ 100.0,f,f,f,f,f,f],_s) psspy.bus_number(101,2) psspy.branchdata(1,2,r"""1""",[i,i,i,i,i,i],[f, 0.2,f,f,f,f,f,f,f,f,f,f,f,f,_f]) psspy.branchdata(1,2,r"""2""",[i,i,i,i,i,i],[f, 0.2,f,f,f,f,f,f,f,f,f,f,f,f,_f]) psspy.plant_data(1,0,[ 1.0, 100.0]) psspy.machinedata2(1,r"""1""",[i,i,i,i,i,i],[ 50.0, 10.0,f,f,f,f,f,f,f,f, 0.2,f,f,f,f,f,f]) psspy.plant_data(2,0,[ 1.0, 100.0]) psspy.machinedata2(2,r"""1""",[i,i,i,i,i,i],[ 50.0, 10.0,f,f,f,f,f,f,f,f,f,f,f,f,f,f,_f]) psspy.loaddata4(2,r"""1""",[i,i,i,i,i,i],[ 100.0, 50.0,f,f,f,f]) psspy.save(r"""C:\Users\m\Desktop\Test\SMIB.sav""") psspy.fdns([0,0,0,1,1,0,99,0]) psspy.fdns([0,0,0,1,1,0,99,0]) psspy.cong(0) psspy.conl(0,1,1,[0,0],[ 100.0,0.0,0.0, 100.0]) psspy.conl(0,1,2,[0,0],[ 100.0,0.0,0.0, 100.0]) psspy.conl(0,1,3,[0,0],[ 100.0,0.0,0.0, 100.0]) psspy.fact() psspy.tysl(1) psspy.save(r"""C:\Users\m\Desktop\Test\SIMBconv.sav""") psspy.dyre_new([1,1,1,1],r"""C:\Users\mg\Desktop\Test\SMIB.dyr""",r"""CC1""",r"""CT1""",r"""N1,N2,N3""") psspy.machinearraychannel([1,1,1],r"""1""","")# Angle M1 psspy.machinearraychannel([2,7,1],r"""1""","")#speed M1 psspy.machinearraychannel([3,1,2],r"""1""","")# Angle M2 psspy.machinearraychannel([4,7,2],r"""1""","")#speed M2 psspy.voltageandangle_channel([7,4,2,1],["",""])# Voltage and Angle Bus 1 psspy.voltageandangle_channel([9,6,3,2 ...
