摘要(Abstract)：
传统继电保护仅利用本单元的电气量及有限的状态量完成故障判断,不能反映电网的整体运行状况,相互之间缺乏协调配合,为此提出了站域保护的基本概念。研究了适用于智能变电站的站域保护逻辑结构,站域保护系统通过交换机和以太网实现了变电站内智能设备间信息的共享和互操作,系统釆用集中式的处理结构,利用多信息进行故障定位。结合典型的500 k V变电站接线,分析了按电压等级构建的站域保护配置方案。基于智能变电站信息共享的站域保护信息量完整,改善了传统继电保护的不足,能提升继电保护性能和系统安全稳定运行能力。
For conventional relay protection, the electrical quantity and limited quantity of state are used for fault diagnosis. The two kinds of quantity are not enough to reflect the overall operation of power grid and lack coordination and cooperation. Therefore, the paper proposes a basic concept of substation area protection and investigates substation area protection logic structure applicable to intelligent substations. The substation area protection system enables information among intelligent devices in substation to share and interoperate via exchanger and Ethernet; it uses a structure of centralized processing and employs multiple information for fault location. Combining typical 500 k V substation wiring, the paper analyzes substation area protection configuration scheme established in line with voltage class. The substation area protection based on information sharing of intelligent substation, owning complete information quantity and improving disadvantages of conventional relay protection, can enhance relay protection performance and operation safety and stability.
