Abstract
Provided is a method for estimating optimal efficiency point parameters in an axial-flow PAT power generation mode, including: I1, calculating an axial velocity of an optimal efficiency point; I2, calculating a flow rate of the optimal efficiency point; I3, calculating a theoretical hydraulic head; I4, calculating a frictional hydraulic head loss and a local hydraulic head loss of each segment; I5, calculating an output power of the optimal efficiency point; I6, calculating a hydraulic head of the optimal efficiency point in a power generation mode; and I7, calculating an optimal efficiency. Further provided is a method for estimating a performance curve in an axial-flow PAT power generation mode based on the above method for estimating an optimal efficiency point parameter, including: II1, calculating a normalized flow-hydraulic head curve; II2, calculating a normalized hydraulic head-output power curve; and II3, calculating a hydraulic head-efficiency curve.
