摘要 谐波是衡量电力质量、设备电气特性的重要指标之一。随着电力系统的迅速发展和新型电气设备的出现,电力系统的谐波问题日趋严重。本文对电气设备中的谐波造成的危害影响进行了分析,并在此基础上,着重分析了谐波对各种继电保护装置的影响,提出了抑制和消除谐波的方法,对于改善设备的电气特性有一定的借鉴意义。 Harmonic is one of the most important indexes of electricity's quality and electrical equipment's specialty. As the development of electric system and appearance of new style electrical equipment, the problem of harmonic in electric system has been more and more serious. In this paper, the harmfulness of harmonic in electrical equipments was analyzed, on which basis, the influence of harmonic to relay protection equipment was analyzed outstandingly, and in the end, the relevant advices of restraining and eliminating technology were also given out. All analysis was signification for improving the equipments' electrical specialty.
