摘要
针对谐波对煤矿井下供电系统不仅产生严重扰动,而且还耗费较多功率等问题,对煤矿井下供电动态无功补偿与谐波抑制装置进行了研究。对煤矿井下供电系统谐波进行了详细分析,另外还研究分析了反馈控制式及前馈控制式并联混合型有源电力滤波器,并设计了复合控制式并联混合型有源电力滤波器,最后针对该滤波器进行了实验分析,其结果表明该装置能够很好地补偿无功功率,在很大程度上缩减系统谐波电流,提升了功率因数,很好地改善了煤矿电能质量,为后继研究提供了科学参考。
Abstract： In order to solve the problem that the power supply system of coal mine is not only serious, but also consumes more reactive power, the dynamic reactive power compensation and harmonic suppression device of coal mine power supply are studied. Analyzes the feedback control and feedforward control type parallel hybrid active power filter, and designs a composite control type parallel hybrid active power filter, and finally analyzes the feedback of the coal mine underground power supply system. The experimental results show that the device can compensate the reactive power very well, reduce the harmonic current of the system to a great extent, improve the power factor, improve the power quality of the coal mine, research provides a scientific reference.
