Definition of Optimization for Running Configuration of High Voltage Direct Current System

High voltage direct current voltage control strategy is related to operational connection mode.This paper analyzes impact on high voltage direct current system by changes of another electrode and condition of disconnector and breaker connecting with direct current field when one electrode of the high voltage direct current running by the way of metallic return operation.Aiming at discrimination logic for connection mode of direct current system,it proposes improvement suggestions which is to make discrimination method for operational connection mode of high voltage direct current system more reasonable and avoid impact on operation of the direct current system.
