截至1986年年底,我国小水电的发电装机容量已超过1,000万kW。主要靠小水电供电的县已达712个,约占全国县数的1/3。近年来,随着小水电电网内发电装机规模的扩大,用电负荷的增长,网内峰谷差和电源丰、枯出力相差甚大的矛盾越来越突出,用电单位对供电的可靠程度、电能质量的要求也越来越强烈。因此,在小水电网内导求调节电源,已成为当务之急。目前,可供选择的调节电源主要有四 As of the end of 1986, China’s small hydropower installed capacity of more than 10 million kW. The number of counties mainly powered by small hydropower has reached 712, accounting for about 1/3 of the total number of counties in the country. In recent years, with the expansion of power generation installed capacity in small hydropower grids, the increase of electricity load, the contradiction between the difference between peak and valley in the network and the abundance of power supply and power output has become more and more prominent. The reliability of power supply units, Power quality requirements are also getting stronger and stronger. Therefore, in the small hydropower network to guide the regulation of power supply, has become a top priority. Currently, there are four main options for regulating power
