Hi all,
I wonder if we can read value of variables during dynamic simulation? For example, checking line flow during dynamic simulation, and add some conditions based on that. Since we run simulation (psspy.run) up to a stop time, does psse provide this facility to have the variables values as real time output existed during simulation? ( to be clear, I am not talking about output retrieval from channel setup).
Hi, I did it for a wind machine writing in Python code:
ierr, ival = psspy.windmind(91003,"""S1""", 'WAUX','VAR') psspy.varchannel([-1,ival] ,"""Vref""") psspy.varchannel([-1,ival+1] ,"""Qref""") psspy.varchannel([-1,ival+7] ,"""Q/V deadband""") psspy.varchannel([-1,ival+5] ,"""Q line flow in MVar""")
ierr, ival = psspy.windmind(91003,"""S1""", 'WAUX','STATE') psspy.varchannel([-1,ival] ,"""Voltage measurement filter""") psspy.varchannel([-1,ival+2] ,"""PI Q""") psspy.var_channel([-1,ival+3] ,"""Lead lag in reactive power path""")
You can use API to get the actual value at end of simulation (stop time). It is also possible to run the simulation in steps and get the value at each pause.
As I understand you want to retrieve the values for each time step during the simulation, and that is only possible via channels.
