Abstract
With the development and application of IT and communication in power system, numerical current differential protection system has been developed, which facilitate the wide area current differential protection system. An expert system is proposed to select primary and backup protection zone online with system configuration information available from SCADA system, the protection units of the same protection zone communicate with each other and the protected units can thus be protected with current differential protection. Knowledge representation and search strategy has been proposed and the expert system has been applied to select primary and backup protection zone for two cases of system configuration.
