智能变电站与传统变电站的继电保护技术研究

Research on Relay Protection Technology between Intelligent Substation and Traditional Substation

与传统变电站相比,智能变电站具有一次设备智能化、二次设备网络化、信息共享标准化的特点。继电保护的关键技术,如采样、跳闸、定时和通信等也与传统变电站不同。本文介绍了110 k V智能变电站的保护配置,指出了智能变电站与传统变电站在运维上的差异,并为有效提高智能变电站运维管理水平提出了建议。

Compared with traditional substation,intelligent substation has the characteristics of intellectualization of primary equipment,networking of secondary equipment and standardization of information sharing.The key technologies of relay protection,such as sampling,tripping,timing and communication,are also different from those of traditional substations.This paper introduced the relay protection configuration of 110 kV intelligent substation,pointed out the differences between intelligent substation and traditional substation in operation and maintenance,and offered some suggestions for improving the operation and maintenance management level of intelligent substation effectively.
