Fast valving initiation
I'm using governor model TGVO2 for steam turbine. It has a function of fast valving. I want to know how can i actuate (or initiate) fast valving.

VAR(L+1) specifies the time for initiating fast valving.
At initialisation of simulation VAR(L+1) is set to 9999 by PSSE. Change the value to the wanted time for start of fast valving. For example 1.3 if you want to initiate at time=1.3 s.
In a script use API:
psspy.change_plmod_var(ibus, id, ’TGOV2’, 2, 1.3)
After that you just run the simulation.
Thank you for the reply. Can you elaborate what is called by VAR(L+1)
Now it is successfully triggered for given time in API. Now i want to trigger this fast valving for a given frequency value. Is it possible??
I have two more thing to clarify, 1. Once FV is activated when frequency exceed a certain value, is there a way to deactivate FV when frequency decrease.
