电力系统中谐波对继电保护的影响

在我国经济社会快速发展的形势下，企业生产和居民生活对电力的需求越来越大，安全用电显得更加重要，如果发生大面积的停电事故，将给企业造成巨大的经济损失，影响百姓的正常生活,同时还会影响社会稳定。因此，相关部门必须重视保障电网安全与稳定运行的继电保护技术。文章分析了电力谐波对继电保护的影响，并提出消除影响的措施，以期为电网保护工作提供借鉴。

The Effects of the Harmonic Wave of Power System on Relay Protection

Against the backdrop of the rapid development of China＇s economics and society, the needs of enterprises＇ production and people＇s living for power are more and more. In this case, safety in utilizing electric energy is very significant. If too many power cut accidents occur, they will bring huge economic losses into enterprises and have effects on both people＇s normal lives and social stability. Therefore, the related departments must attach the importance to the safety of power grid and the stable relay protection. The paper analyzes the effects of power harmonic wave on relay protection, and puts forward the measures to eliminate the effects, for the reference of the power grid＇s protection work.
