Abstrakt: Comprehensive conversion efficiency reflects the operation benefit of pumped storage power station. Analysing and studying the main influence factor for the comprehensive conversion efficiency is important to the overall design of power plant and to the improvement of comprehensive conversion efficiency. This paper adopts the method of combining field efficiency test with daily operation data analysis. By comparing and checking the test results with the model test results and the unit performance acceptance test results, the unit efficiency characteristics are defined. Through the analysis of daily operation data, the influence of unit operation mode on efficiency is clarified. Finally, it is concluded that the level of unit efficiency and generation operation mode are the main factors affecting the comprehensive conversion efficiency of power plants.
