1 抽水蓄能电站抽水蓄能电站不同于一般的水力发电站。一般的水力发电站是只安装发电机组,将高水位的水一次使用后弃之东流。抽水蓄能电站安装有抽水——发电两用机组,既能抽水,又能发电。在白天和后半夜,水库放水,高水位的水通过两用机组,此时两用机组作为发电机,将高水位的水的机械能转化为电能,向电网输送,解决用电高峰时电力不足;到后半夜,电网处于低谷,电网中不能储存电能,这时将两用机组作为抽水机(利用机组可反向旋转),利用电网中多余的电能将低水位的水抽向高水位的水库中,这样在用电低谷时把电网中多余的电能转化为
1 pumped storage power station Pumped storage power station is different from the average hydroelectric power station. The general hydroelectric power station is installed only the generator set, the high water once the use of abandoned after the East. Pumped storage power station installed pumping - generating dual-use unit, both pumping, but also power generation. In the daytime and middle of the night, the reservoir discharges water and the high-level water passes through dual-purpose units. At this time, the dual-purpose unit serves as a generator to convert the mechanical energy of high-water water into electrical energy and transport it to the grid to solve the shortage of electricity at the peak of electricity supply. By the middle of the night, the power grid will be in the darkest and the power grid will not be able to store the energy. In this case, the dual-purpose unit will be used as a pump (which can be rotated in the opposite direction by the unit) to extract low-level water from the surplus power in the power grid to high-water reservoirs. In this way, the excess electricity in the power grid is converted to electricity when the electricity is running low
