由于非线性信息化设备在煤矿企业建筑供电系统中的大量应用,使得电网电能质量下降,将产生很大的安全隐患。文章对煤矿供电系统中的谐波产生和危害做了简单的介绍,并详细阐述了利用有源电力滤波器进行谐波抑制和无功补偿的原理和方法,同时利用MATLAB进行了仿真。
Due to the large number of applications of nonlinear information equipment in the power supply system of coal mining construction, the power quality of the power grid will decline, which will cause a great potential safety hazard. This paper gives a brief introduction of harmonic generation and harm in coal mine power supply system, and elaborates the principle and method of using harmonic suppression and reactive power compensation of active power filter in detail. At the same time, it simulates with MATLAB.
