This is a hypothetical scenario considering that there is no protection is in place to prevent the following:
While backfeeding a combined cycle power plant via the GSU [HS (System Side) connected in Wye and LS (Gen Side) in Delta] the upstream switchyard breaker opens but only:
a) 1 pole opens
b) 2 poles open
What negative effects or concerns, if any, will the GSU (~350MVA) encounter by carrying an unbalanced load for an X amount of time given scenarios a or b?
Appreciate the input, Thanks!
