| Relay protection device as an important equipment in power grid operation,it can remove the power grid fault quickly,and plays an important role for the safe operation of power grid.With rapid development of power grid scale,power grid operation mode change frequently,so the requirement of relay protection device operation mode will adjust.The traditional relay protection device operation mode requires staff to go to the substation operating relay protection in a manual way,the efficiency is very low,it is difficult to meet the needs of power grid operation change.If staffs can operate relay protection in distance,they will not need to go to the substation any more,it greatly enhances the working efficiency and the level of power grid operation and management.Therefore,the realization of relay protection device of the remote operating function is very necessary.This paper mainly studied the relay protection device of the remote operating function concrete realization.Firstly,based on the research results of SGDnet,substation supervision and control system,the relay protection fault information system in southern hebei power grid,and the previous research,a variety of projects are put forward,then demonstrate these projects.Finally,we choose to develop a software,based on the remote desktop,to realize remote operation of the relay protection device.Then chose the programming language used to develop this system and introduced the useof some key technologies.Then completed the system design and system frame is presented,completed the programming of software and related code is presented.Finally tested this system in SIFANG CSC200 substation monitoring system environment,satisfied the functional requirements,reached the desired effect. |
