摘要
以矿井直流提升机供电系统产生的谐波为研究对象,采用动态谐波检测和抑制方法,对电网进行了谐波治理与无功补偿。运行MATLAB软件仿真了其谐波特性,并进行谐波动态检测和抑制仿真,仿真结果表明:该方法可以实时检测提升机供电系统中的谐波,并可对谐波进行有效抑制,经过该有源滤波器处理后,提升机系统谐波总畸变率降至1%左右,功率因数接近为1。
Token the harmonic wave generated by power supply system of mine dc winder as the re- search target, harmonic wave treatment and reactive power compensation were done on power network by adopted dynamic detection and inhibition methods of harmonic. The harmonic characteristics were simula- ted by MATLAB and dynamic detection and inhibition simulation of harmonic were done. The results in- dicate that this method could test the harmonic in power supply system of hoist timely, and could inhibit harmonic effectively. Through the treatment by active filter, general aberration rate of harmonic of hoist system reduced to around 1% and power factor closed to 1.
