The AC dynamic reactive power compensation in high voltage direct current (HVDC) still remains an unsolved problem. Owing to its flexible and rapid reactive power output, synchronous condenser (SC) has a broad application prospect on sending and receiving ends of HVDC transmission system. Firstly, the system structure of a new large capacity SC is introduced. Secondly, reactive power dynamic characteristics of SC in sub-transient and transient are studied theoretically. Then its supporting effect on low bus voltage is analyzed and verified. On this basis, the reactive power application requirements of SC in DC system are studied. An actual transmission system model is established by PSCAD/EMTDC. The simulation verifies the suppression effect of SC on commutation failure and bus transient overvoltage, which provides a theoretical basis for the application of SC in HVDC system.
