【摘要】 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。更多还原

【Abstract】 Du to non-linear informational equipments are widely used in power supply systems of coal mine enterprises,the performance of the grid is reduced to some extent,which will generate great hazards.This paper briefly introduces the generation and hazards of harmonic wave,and elaborates the principles and methods of suppression on harmonic wave and inactive power compensation through active power filter,meanwhile simulates with MATLAB.更多还原
