Statistical analysis of water power station characteristic parametersmore than 12000 kW in China

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.
