the issue of limiting the over-voltage and inrush current by way of series resistance switch during the switching of shunt capacitor bank in the capacitor bank compensation system of a 500kV EHV substation is studied. The influence of different series resistance values is analyzed through simulation
the recommended resistance values are proposed
and the limiting effects of using ordinary circuit breaker
phase-controlled circuit breaker and series resistance switch on over-voltage and over-current are compared. The results show that the series resistance switch can effectively reduce the probability of reignition and can
at the same time
reduce the over-voltage level after reignition. It is thought from the the economic and technical perspective that the series resistance switch has lower circuit breaker specifications
