摘要
通过阐述相关规程对主变后备保护配置要求和某公司主变后备保护的实际配置情况以及现有后备保护装置的特点,分析了会给黄化电网带来的严重危害,并提出相应的整改措施。以该公司110 kV公伯峡系统为例,详细阐述了每套保护功能及其配置方法,主要对为解决主变高压侧后备保护时限过长和部分保护功能未得到合理应用的缺陷,采取的具体解决办法和使用方案,供继电保护同行参考。
This paper expounds the requirements of some relevant regulations to main transformer backup protection, the real situations and features of our company＇s facilities and the possible consequences. In addition, this paper also puts forward some measures of improvement. It takes the 110kV Gongboxia power system as an example to detail its protective functions and installing methods, and some specific solutions and application patterns are offered mainly to solve the problems of the long time limit of the main transformer back up protection and improper application of its protective functions.
