并联有源滤波器在煤矿谐波抑制中的研究与应用

Research and Application of Active Power Filer in Harmonic Wave Suppression of Coal Mine

由于矿井下非线性设备及变流装置广泛使用,导致一定谐波分量的产生,使得矿井供电系统受到污染,从而降低电能的生产、传输和使用效率。本文介绍了矿井供电系统中谐波的产生和危害,分析了井下并联有源电力滤波器进行谐波抑制的原理和方法,同时采用Matlab进行了仿真验证。

With the widely used of nonlinear equipment and converter device under coal mine,the coal mine power system has been polluted by the produce of harmonic wave component,which reduces the efficiency of electricity generation,transmission and using. This paper simply introduced the pro-duction of harmonic wave and harms in coal mine power system,and expounded on the theory of Ac-tive Power Filter for harmonic suppression and methods,meanwhile simulated with Matlab.
