静止型动态无功补偿装置在松河煤矿的应用

针对传统的固定无功补偿装置只能在一定程度上补偿功率因数,无法解决煤矿大功率负荷软启动装置造成的电网高次谐波污染问题,提出采用静止型动态无功补偿装置来提高功率因数、治理谐波污染的方案;以静止型动态无功补偿装置在松河煤矿的应用为例,介绍了具体的补偿方案及该装置中滤波器的设计,并分析了补偿效果和节能效果。应用结果表明,静止型动态无功补偿装置投运后,将功率因数补偿到0.95以上,且有效抑制了高次谐波,每年可为煤矿节约电费达430万元。

Application of Static Var Compensator in Songhe Coal Mine

In order to solve problems that traditional stationary reactive var compensator only compensates power factor to some extent and cannot eliminate higher harmonic pollution of power network caused by soft starters of high power loads of coal mine,the paper proposed a scheme of using static var compensator to improve power factor and solve harmonic pollution problem.Taking the application of static var compensator in Songhe coal mine as an example,it introduced concrete compensating scheme and design of filter in the compensator,and analyzed compensation and energy-saving effects.The application result showed that the compensator can compensate power factor to 0.95 and restrain higher harmonic effectively,which has perfect energy-saving effect with 4 300 000 yuan saving for Songhe coal mine each year.
