平原地区小水电生产成本低,社会效益高,对电网负荷的调节补充和地方工农业的发展具有一定的作用。但平原地区的小水电大都建在灌溉渠道上,不同于抽水蓄能电站,生产受气候、季节影响较大,加之又要进行峰谷调节,这些因素都制约了经济效益的提高。淮安市运东水电站几 The production cost of small hydropower in the plain area is low, the social benefits are high, and the adjustment and replenishment of the grid load and the development of local agriculture and industry play a certain role. However, most of the small hydropower in the plain area are built on irrigation channels. Unlike the pumped-storage power plants, the production is affected by the climate and the seasons have a great influence. In addition, the adjustment of the peak-valley needs to be carried out. All of these factors restrict the improvement of economic benefits. Huai’an Yun Dong Hydropower Station
