The invention relates to the technical field of pump station flow control, and discloses a method for correcting a pump station flow measuring result. The method comprises the steps of obtaining a three-dimensional model of a pump station system channel; conducting grid dividing on the three-dimensional model; conducting simulating calculating to obtain data of multiple work condition states with the combination of a boundary condition, wherein the data comprises the average velocity v line of a simulating sound track line in the axial direction of a pipeline and the normal average velocity v plane of a pipe section in which the midpoint of the simulating sound track line is located; calculating to obtain a corresponding correction coefficient eta; generating a correction coefficient-flow relation curve, wherein the flow is flow Q simulation on the simulation sound track line; obtaining flow value Q measurement actually measured by an ultrasonic flowmeter, and correcting the Q measurement based on a set relation. According to the method for correcting the pump station flow measuring result, the data measured by the ultrasonic flowmeter which is used by a pump station is corrected, the precision of data is improved, the error in pump station site flow measurement is reduced, and thus the operation of the pump station is more stable and saves more energy.
