动态无功补偿装置在煤矿供电系统中的应用

Application of Dynamic Reactive Power Compensation Device in Coal Mine Power Supply System

国内现有大多数煤矿供电系统中使用SVC静止无功补偿装置,存在系统老化及跟随性差等问题。现将2套6.0 Mvar/6 kV动态无功补偿装置应用在煤矿35 kV变电所供电系统中,不仅稳定6 k V母线电压,提高系统功率因数,同时改善了35 kV电网侧功率因数偏低问题,无功补偿效果明显,保障电网安全稳定运行,取得了良好的经济效益。

SVC static reactive power compensation device is used in most of the existing coal mine power supply system in China. Now two sets of 6.0 Mvar/6 kV dynamic reactive power compensation devices are applied in the power supply system of 35 kV coal mine substation, which not only stabilizes the 6 kV bus voltage and improves the power factor of the system, but also improves the low power factor of 35 kV power grid side. The reactive power compensation effect is obvious, ensuring the safe and stable operation of the power grid and achieving good economic benefits.
