摘要
通过对4条供电线路功率因数偏低的分析,设计确定了补偿方案,并研究解决了无功补偿中的涌流及限制、谐波及防护、过电压及保护等技术难题,设备投运后4条供电线路的功率因数均达到0.95以上,取得了满意的效果。
Through analysis of low power factors of 4 power supply lines the compensa-tion design was determined and technical problems such as surging and limitation, harmonic and protection and over-voltage and protection in wattless power compensation were studied and solved. After the device was put into operation, power factors in the 4 lines have reached 0.95 or more, bringing satisfactory results.
