抽水蓄能电站,是利用水力能源的一种重要方式。它利用用电低峰时电厂过剩的电力,将水从低处抽到高处储存起来;到用电高峰时再用它发电,以补充电力的不足。因此,它像电力银行一样,能储电发电。它的建设费用低,而且不受河流地域的限制,可建在用电中心区域附近,有利于减少电能输送的损失,同时水可以反复利用,随时 Pumped storage power stations are an important way to use hydropower. It uses the surplus power of the power plant when the electricity is at low peaks to pump water from a low point to a high point, and then uses it to generate electricity at peak times to supplement the power shortage. Therefore, like the power bank, it can store electricity and generate electricity. Its construction cost is low, and it is not limited by the river area. It can be built near the electricity center area, which helps to reduce the loss of power transmission. At the same time, water can be used repeatedly.
