千佛洞水电站超发有功功率研究

Study of Extra-generated Active Power of Qianfodong Hydropower Station

千佛洞电站充分利用丰水期水资源,在额定容量的前提下,发电机限制发无功功率,超发有功功率达20%-25%。无功功率不足部分通过装设高压电容无功功率补偿装置进行补偿。实际应用表明该项措施充分利用了水资源,提高了发电机的能效,取得了良好的社会效益和经济效益。

Qianfodong hydropower station takes full advantage of water resources during wet period,thereby the power generators are limited to generate inactive power under the premise of the rated capacity,and the extra-generated active power is up to 20-25 %.The insufficient part of inactive power can be compensated through installation of high-voltage capacitor reactive power compensation device.The actual application shows that the measures make full use of the water resources,improve the energy efficiency of the generator,and achieve good social and economic benefits.
