矿山电网谐波的抑制分析及有源谐波滤波器的应用

Harmonic Analysis of Suppression and Application Active Power Harmonic Filter of Power Network in Mine

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。

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.
