水电蓄能运行在促进和发展循环经济中的作用

当前我国水电开发速度很快，较好的电源站点在20年内将开发殆尽，会影响水资源的持续开发。因此水利水电要与其他资源一道和谐相处、共谋发展。水利水电的蓄能运行是在电网中利用非峰荷剩余电能抽水蓄能，以供峰荷时再次发电或供水灌溉，形成水资源、能源和其他资源的相互转换、相互支持、以丰补歉、循环再生利用，必将在促进和发展循环经济中发挥很大作用。

Roles of pumped-storage energy in promoting development of recycled economy

The speed of hydropower development is very fast at present. Relatively good sites for development shall be all exploited in the next 20 years, which will has a negative impact on sustainable utilization of water resources. Therefore, hydropower development should be integrated or harmonized with the development of other resources. Pumped-storage power station pumps the surplus water during non-peak load in the grid for generating electricity in peak load for water supply or irrigation. A recycling of water resources and energy or other resources is realized that will play a big role in the development of recycled economy.
