【 摘 要 】

A new evaluation method was proposed for the determination of economic operation zone of large hydrogenerators. Firstly, a large number of test data were obtained by carrying out efficiency tests of the turbine at different heads. Secondly, through data analysis, the value method of K0 and the water consumption rate were constructed to determine the economic operation zone and the optimal economic operation zone, separately. Thirdly, the validity of the proposed method was verified by applying to an actual hydrogenerator. Compared with traditional methods, this method can be used to guide the economic operation of hydropower plants.
