Abstract :
This paper analyzes the different operation modes of the UHVDC system sharing earth electrode from the aspect of power system stable operation. Two UHVDC system rectifiers and inverters sharing earth electrode were studied respectively by electromagnetic transient analysis software EMTP-RV based on the main parameters of Xiang jiaba to Nan hui plusmn800 kV UHVDC transmission system. The influence on the normal operation of UHVDC system sharing earth electrode is simulated and analyzed. The merits and demerits of sharing earth electrode are summarized in detail. The feasible suggestions for the corresponding control and protection of UHVDC system sharing earth electrode are put forward.
