摘要
大型水力发电厂厂用电系统结构复杂,厂用电保护的配合问题日渐突出。三峡电厂厂用电系统的保护整定可以代表性地解决复杂厂用电系统的保护定值配合问题。文中简要介绍了三峡电厂厂用电系统的运行方式,针对保护整定过程中遇到的诸多配合问题一一提出解决方案。按此方法整定,在实际运行中,三峡电厂厂用电未出现定值配合不当导致的保护误动或拒动。
Owing to the development of power systems, the structure of the service power system in many large hydropower plants is complex, and the cooperation of relay protection becomes more and more important. The Three Gorges Hydropower Plant is a good example with a complex service power system. The operation mode of the service power system in the Three Gorges Hydropower Plant is introduced, and some representative problems concerningy the cooperation of relay protection setting are raised and solved successfully.
