摘　　要：目前,各个电厂基本上都有继电保护,虽然继电保护对电厂安全起到了重要的作用,但很多电厂面临着二次回路的设计缺陷,影响了继电保护功能的实现。因此,各个电厂在都应该注重二次回路的改造设计和优化,为电厂提供相对安全、稳定的电路条件。基于此,文章重点分析了电厂继电保护二次回路的改造设计要点,对电厂的电路优化具有一定的指导价值。At present,all power plants basically have relay protection.Although relay protection plays an important role in power plant safety,many power plants face design flaws in the secondary circuit,which affect the realization of relay protection functions.Therefore,each power plant should pay attention to the design and optimization of the secondary loop to provide relatively safe and stable circuit conditions for the power plant.Based on this,the article focuses on the main points of the reformation design of the power plant relay protection secondary circuit,which has a certain guiding value for the circuit optimization of the power plant.
