The control and protection(C&P) system of DC converter station is one of the key techniques in HVDC project. The situation and development of DC C&P system is very important for HVDC technique utilization. This paper expounds the control strategy and the steady, dynamic and transient performances for both of typical DC C&P and DC C&P in Three Gorges to Changzhou project, according to the project specification and the FST. This paper describes the main configuration and features of updating C&P system of DC converter station. The service conditions of control strategy and system configuration of Three Gorges to Changzhou DC Project are analyzed. Finally, some proposals for design the complete set of DC C&P system are given: to follow closely up the development of electron technology; it is more important to develop the remote control and to utilize the DC C&P to make the power grid more safe and stable.
