矿山电网谐波的抑制分析及有源谐波滤波器的应用

摘要

With the development of science and technology, more and more non-linear electrical equipment such as SCR Rectifier unit, in⁃verter, circulating ventilation fans, and other applications in the mine production system, followed by harmonic hazard problem is getting aroused widespread concern. This thesis together along with a large area of the mine blackout, study and analysisthe hazards of harmonic in mine production and test result using FLUKE435 three-phase power quality analyzer to verify the good active power filtering performance of the active filter in mine power net.%　　随着科技的发展,越来越多的非线性的电气设备如可控硅整流器,变频器,斩波器等应用在了矿山生产系统中,随之而来的谐波危害的问题越来越引起广泛关注。通过一起矿山的大面积停电事故,研究并分析了谐波对矿山生产所带来的危害,并使用三相电能质量测试仪FLUKE435,验证了有源滤波器在矿山电网中的良好滤波性能。
