链接提高线路的功率因数是一项重要的降损措施,在10千伏线路中最常用的方法就是安装固定补偿电容器组,它最大的优点是投资少,但它却存在安全性差,不适宜频繁操作等缺点,并且由于它是固定补偿方式,不能随线路的负荷变化调整补偿容量。而线路上的负荷是时刻变化的,尤其是日、夜负荷和季节性负荷变化比较大, Links to increase the power factor of the line is an important loss reduction measures, the most commonly used method in the 10 kV line is to install fixed compensation capacitor bank, its biggest advantage is less investment, but it has poor security, not suitable for frequent Operation and other shortcomings, and because it is a fixed compensation, can not adjust the compensation capacity with the line load changes. The load on the line is always changing, especially in Japan, night load and seasonal load changes relatively large,
