As the second generation of FACTS products, static synchronous compensator (STATCOM) can dynamically compensate for the reactive power of the system, thereby improving the operating characteristics of the system. The STATCOM is connected to the HVDC inverter AC bus, and the HVDC transmission system model with STATCOM is established. The effect of STATCOM on the commutation failure and DC power recovery time is studied by PSCAD / EMTDC simulation in different types and levels of fault. The

Commutation Failure of HVDC As the most typical system fault of HVDC transmission system, commutation failure will cause the AC voltage to drop, the DC current to increase for a short time and so on.
