Design And Application Of Relay Protection Remote Control System Based On Smart Grid Dispatching And Control System

With the development of smart grid dispatching and control system, the unattended substation operation mode has been widely used therefore relay protection remote control needs to be enhanced to accomplish the integration of power dispatching and control. This article is based on IEC 60870-5-104 protocol published by IEC, researched online setting area switching, relay plate switching and setting modification which embedded in new generation of smart grid dispatching and control system. By contrast with the traditional methods, this newly designed system focus on preventing incorrect operation, data rationality optimization and standardized operational procedure, significantly improved the reliability and accuracy of remote operation. Practices prove that the application of this system tremendously save the cost of daily maintenance, increase the working efficiency; decrease the potential safety risk which is deserved being highly popularized.
