摘　　要：针对矿井配电系统中的负荷特点,对采用交流变频调速控制的矿井提升机系统产生的无功冲击和谐波污染进行了专项测试,结果表明其功率因数偏低、无功波动大、谐波污染严重超过国家标准要求,迫切需要治理。文章从性能和成本角度出发综合比较了有源滤波器(APF)、动态无功补偿装置(TSC)和"APF+TSC"装置3种治理补偿方案。针对项目实际情况,提出APF+TSC的混合治理方案并阐述了混合滤波补偿方案在非线性冲击性负荷的电能质量治理上的优势。工程实施后的现场测试结果验证了本文治理方案的有效性。According to the load characteristics of mine distribution system, it tested the pollutions of non-active power and harmonics produced by mine upgrade machine system with AC frequency conversion speed control. Test results show that not only its power factor is lower, but also its non-active power fluctuation is larger. In addition, the harmonic pollution exceeds limits seriously according to the national standards requirements. Three schemes based on active power filter（APF） and/or thyristor-switched capacitor（TSC） were given. By comparing the performance and cost of these schemes, the advantages of hybrid power filter compensation in power quality management of nonlinear impulse load are clarified. The effectiveness of the scheme mentioned is verified by practical test on site.
