Calculation Method for Pump Turbine Efficiency in Pumped Storage Power Station
摘要
Abstract
This paper introduces role of pumped storage power station in power grid and states important meaning of calculation on u-nit efficiency. Aiming at energy loss in process of complicated running of pumped turbine,a kind of calculation method for pumped turbine efficiency based on least square method for surface fitting was proposed and fitting model for pumped turbine efficiency was established. Comparison and analysis on fitting results proves higher fitting precision. Specific calculation example indicated that it was able to work out efficiency of the pumped turbine under generating work condition and pumping operation mode of the pumped storage power station by using principle of least square method for surface fitting.关键词
