摘　　要：针对晋圣固隆煤业有限公司现场无功功率、电网谐波、设备瞬间启动等三种供电问题,根据无功补偿原理,研究设计了无功发生器,将装置与电网并联,实现对电网谐波和无功的即时检测,并对谐波和无功电流进行补偿,线路损耗降低了大约51%左右,电网谐波问题、大型设备启动问题大大减少。Aiming at the three power supply problems of Jinsheng Gulong Coal Industry Co., Ltd. such as reactive power, harmonic of power grid and instantaneous start of equipment, according to the principle of reactive power compensation, the reactive power generator is studied and designed. The device is connected with power grid in parallel to realize the instantaneous detection of harmonic and reactive power in power grid, and the harmonic and reactive current are compensated. The loss is reduced by about 51%, and the harmonic problem of the power network and the start-up of large equipment are greatly reduced.
