小水电站一般装机容量小 ,遍布边远山区 ,由于设备不配套 ,电能损耗较大 ,欠发无功的现象特别严重。小水电站发出的电量 ,除部分供当地负荷外 ,大部分通过上网点向系统电网销售。目前收购的上网电 ,在计量计费点 ,按功率因数等于 0 .8计算 ,即 1ｋＷ·ｈ功配0 .75ｋＶａｒ·ｈ? Small hydropower stations generally have small installed capacity and are located in remote mountainous areas. Due to the lack of facilities, the power loss is large, and the phenomenon of less power and reactive power is particularly serious. The amount of electricity sent by small hydropower stations, except for part of the local load, the majority of the outlets through the system to the grid. The current acquisition of the Internet, in the billing point, calculated by the power factor is equal to 0.8, that 1kW · h power distribution 0.75kVar · h?
