摘　　要：矿山企业的矿井配电系统受大功率冲击性负荷的影响,电网系统功率因数低,电压波形严重畸变,影响电网的安全及提升系统的稳定性。以某矿副井提升机电网的实际情况为背景,利用有源电力滤波器及动态无功补偿装置,研究副井提升电气系统谐波治理及动态无功补偿技术,加装静止无功发生器来改善系统功率因素过低以及谐波含量较高的问题。经实际验证,该方式在能耗、电流和电压治理方面效果显著。The mine power distribution system of mining enterprises is affected by high-power impact loads,resulting in low power factor and severe voltage waveform distortion in the power grid system,which affects the safety of the power grid and the stability of the hoisting system.In this paper,based on the actual situation of the electrical network of a certain mine auxiliary shaft hoist,active power filters and dynamic reactive power compensation devices were used to study the harmonic control and dynamic reactive power compensation technology of the electrical system of the auxiliary shaft hoist.Then,static reactive power generators were installed to solve the problem of low power factor and high harmonic content in the system.Through practical verification,significant effects had been achieved in energy consumption,current,and voltage management.
