Research on Protection Principle and Field Calibration and Debugging Method of 500 kV Shunt Reactor

从超高压输电线路并联电抗器保护装置的工作原理入手,在详细介绍差动保护、匝间保护原理和动作特性的基础上,提出了一种电抗器保护原理、保护定值的现场调试方法。该调试方法能及时发现并消除设备缺陷,满足实际工程需要,为今后超高压输电线路并联电抗器保护装置的设计、运行和维护积累了宝贵的经验。

Starting from the working principle of the parallel reactor protection device for ultra-high voltage transmission lines,and on the basis of detailed introduction of differential protection,inter-turn protection principle and action characteristics,a reactor protection principle and a field debugging method of protection setting are proposed.This debugging method can detect and eliminate equipment defects in time,meet actual engineering needs,and accumulate valuable experience for the design,operation and maintenance of parallel reactor protection devices for ultra-high voltage transmission lines in the future.
