Operation and Development of Power Network Protection in Recent Years in China

The paper briefly reviewed the new development of the protection in recent years, such as raising of protection operation level unceasingly, increasing of microcomputer-based protection of HV power network steadily, application of advanced technology and management means, and localization of parts and components for control and protective equipment of EHVDC and SC. The developing direction of the protection in the future is looked ahead, and combined with the requirements of power network development, the key problems that need to be solved recently for the protection are put forward.
