Hi all, I am a new user of PSSE. I would like to put in-service a fixed shunt during a dynamic simulation in the initialization is out-service. I really do not know the command which command to use. Can anyone give me a hand with the command? I have searched it but I still do not know. Thanks!

The Disturbance APIs section of the documentation doesn't give functionality for tripping or reconnecting shunts. I'd suggest you could move the shunt to a new bus, which is out of service, but connected to the original bus via a zero impedance line. During the dynamic simulation, you could use busdata2 to change the bus code to 1 (in-service) before using DISTBRANCHCLOSE to connect the bus (shunt and all).

The requested API is found in "Power Flow Data Changing" instead. It is just to use psspy.shunt_chng(i, id, 1) to switch on the shunt during the dynamic simulation.

From one of used files:

To add shunt

psspy.shunt_data(bus#,r""":""",1,[0.0,0.0])

psspy.shuntchng(bus#,r""":""",i,[_f, -267.0]) #comment -267 MVAR shunt.

To remove shunt

psspy.shuntchng(bus#,r""":""",0,[f,_f])

over and out.
