The new high-capacity condenser can better meet the dynamic reactive power demand brought by the large-scale development of UHVDC System, and its electrical parameters are bound to be different from the traditional condenser. In this paper, the influence of electrical parameters on the transient process and sub transient process of the condenser is analyzed, and the key parameters of the dynamic optimization of the new high-capacity condenser are extracted. Then, based on epri-36 bus system and PSASP simulation platform, the DC sending and receiving system with the new high-capacity condenser is simulated and analyzed. The simulation results show that the condenser is in UHV AC / DC system. The hybrid system plays a positive role in fault response.
