摘要
本文对全国134座装机1.2万kW以上水电站的5项主要特征值参数———多年平均流量Q、水库有效库容V、水轮机组设计水头H、电站装机容量N、平均年发电量E,及由此而派生的5个无尺度数———库容系数α、流量～水头比ω、装机系数β、运行系数τ、电能系数ε,进行无尺度统计分析,使134座水电站得以进行综合性归纳比较,同时对特征值之间的关系进一步加深认识。
The paper analyses five principal characteristic parameter values of 134 water power stations more than 12000 kW in China- average annual flow, effective storage of reservoir, design water head of turbine, installed capacity of water power station, average annual energy output and five dimensionless factors- storage coefficient, discharge- water head ration, installed capacity coefficient, operation coefficient, electric energy coefficient, it makes 134 water power stations to compare comprehensively and to understand thoroughly the relation between characteristic parameter values.
