The comparison about methods of organizing network for protective relay and fault message system sub station in Ningxia Power Grid

随着电力系统自身体系的日益成熟与完善,计算机技术的不断发展,继电保护及故障信息系统开始大规模应用,使得运行于电网的故障录波器和微机保护等安全自动装置均处于网络运行状态,该系统具有智能化的分析功能以及先进的管理模式,给日趋复杂的电网故障快速处理奠定了基础。本文就继电保护及故障信息子站的3种组网方案进行了技术比较。

With the Power system itself mature and perfect day by day, as well as the ever developing of the computer technology, protective relay and fault message system come into existence in more and more projects. This put all the automatic safety equipment such as fault wave recorder and microprocessor based protection into the state of network operation. The system has intelligentized analysis and advanced management pattern, which lay a good foundation for dealing with fault in good time in the more and more complicated power grid, The paper gives technologic comparison among three methods of organizing the network for protective relay and fault message system sub station.
