Research and Implementation of Centralized Intelligent Substation Protection and Control System

A centralized mode of protection and control system based on digital information is proposed, communications platform networking, information sharing standardized characteristics of intelligent substation. This model describes the centralized protection and control system architecture and its main hardware, research on the time required for the system strategy and the "triple nets" and other key technologies, and put into implemented and applied. At Hejia 220kV substation intelligent centralized protection and control system set its key consideration on functional integration, improve equipment integration, optimize resources, and information sharing, System model for the future direction of development of intelligent substation has a leading and exemplary role.
