Abstract
Shunt capacitors are widely used in power system for reactive power compensation. However
the overvoltage and over current will be generated in the compensation device during its switch-on and switch-off operation
even the insulation of capacitor bank can be damaged and the safe and stable operation of the power grid is affected. In this paper
based on transient simulation software of EMTP/ATP power system
the reactive power compensation simulation model of 330 kV substation is set up to simulate the internal overvoltage of capacitor bank at synchronous and asynchronous opening of circuit breaker.
