滤波无功补偿技术在煤矿高压供电系统的应用

Application of filtering reactive power compensation technology in high voltage power supply system of coal mine

某矿地面高压供电系统由于负荷变化及使用非线性设备,使电能质量达不到规定要求。经设计,矿井北区供电系统采用就地补偿装置,南区供电系统采用FC滤波支路设备+静态无功补偿装置。运行表明,使用该技术,设备投资少,达到了预期目的。

The power quality in high voltage power supply of a coal mine is not required owing to the load change and the use of nonlinear equipment. After design, the local compensation device of the power supply system in the north area of the mine is used , and FC filter branch equipment and static reactive power compensation device of power supply system in the southern district are adopted. Operation result shows that the use of this technology may reduce the equipment investment and achieve the desired objective.
