Design of remote centralized control center for multi-circuit HVDC system

Abstract

The development planning and implementing scheme of the remote HVDC centralized control center about to be established in South China Power Grid are discussed. Such related key technologies are analyzed as functions, management, automatic management mode, SCADA system, communication and information exchange. As a conclusion, it is feasible to realize the centralized control of multi-circuit HVDC system, and the construction process can be implemented in three steps. Moreover, its construction will facilitate the HVDC control mode updating from local level to high accessorial control and AC&DC cooperation control, and improve the stability of the whole power gird.
