Optimization design and application of converter parameters of DC vacuum circuit breaker
With the R&D of high voltage direct current (HVDC) transmission, HVDC circuit breaker as the protection equipment has been widely applied in the power system. In this paper, the HVDC vacuum circuit breaker (VCB) based on artificial zero mode has been analyzed, and the genetic algorithm (GA) has been used to optimize the parameters of DC VCB. Moreover, an optimization design method of converting parameters for HVDC VCB has been presented and applied to the optimization of converter parameters for DC VCB. The simulation result has shown that the proposed method can improve the interrupting performance of the DC VCB.
