Typically how much do transmission voltages 115kv and over vary? Or to be candid what would you think about a distribution substation without voltage regulation?
I have a situation where a substation voltage regulator needs to be bypassed for an extended period of time, relying entirely on the ratio of the 30/40/50MVA power transformer itself.
PSS/E is giving me steady state variances between 118kv and 114kv, and worst case N-1-1 contingencies of 111kv. Not as bad as I assumed.
I'm thinking of placing the primary no load taps at 112.125kv over from 115kv covering me well enough. Thoughts welcome.
