Fast Valving Actuation

Hello Everyone,

Can someone help me how to initiate a fast valving via code using CONEC at PSS/E dynamic simulation? Or if possible can you provide me valve opening and closing time values (TA, TB, TC, T1) for model TGOV2?

I am designing a simple power system with two remote generating sources and should withstand a 10-cy single-phase fault delayed clearing with line outage. The idea is to improve stability via fast valving and modification of excitation system parameters.

Thank you so much!

Seems to be a very weak system since it is unstable for a 10-cycles single-phase fault. Use TGOV2 to analyse how fast the fast valving must act to ensure transient stability. The tricky thing is to decide the criterion for inititiating fast valving.

@perolofl It is really a weak system! Just trying to analyze countermeasures to instability. When I use ALTR to initiate fast valving actuation, the system is still unstable. I want to do it in such a way that it will activate when certain speed deviation is exceeded.
