我国南方地区许多农村电力系统都以水电为主,水电中又以迳流式水电站占的比重较大。作为系统的工作容量,迳流式水电站多是担负系统的基荷,在系统的电力电量平衡中,迳流式水电站的工作容量一般拉保证出力而定,即N工作=N保证。这种方法把全年各个季节的工作容量当成一个常数,过于保守。鉴于天然迳流在一年内有丰、平、枯之差,而迳流式电 Many rural power systems in the southern part of our country are mainly hydropower. Hydropower has a larger proportion of hydropower stations. As the working capacity of the system, the 迳 -type hydropower station is mostly the base load of the system. In the system of power balance, the working capacity of the 迳 -type hydropower station generally depends on the output, that is, N = N. This method treats the working capacity of all seasons throughout the year as a constant, too conservative. Given the abundance, flatness and wastage of natural 迳-flow within a year, 迳-flow electricity
