The present states of flow and efficiency site test for the performance measurement of large water power set at home and abroad are introduced. The difference between prototype and model and its' contrast test are analyzed,The contrast test must satisfy following advanced, 1 . Selected test water power station accords with IEC regulations; 2 . The power station is not tested by all side of participants,treatment mode of each one flow value is together appsoved; 3. Flow is measured many a time at same steady operating mode, using together decided error caculation methed; 4. At the same, Volute pressure difference is measured, calculating the linear correlative coefficient between flow and square root of the prssure difference. Then a right contrast consideration and judgement can be given. the flow measuring methods of pressure-time, flow velometer, ultrasonic and volute pressure difference are analyzed. Its advantages and shortages are contrasted. New pressure-time methed is recommended used for the efficiency acceptance test of internal large and giant water turbine, and suggesting in accordance with ne-cessorily satisfied conditions and demands, at the same set several contrast efficiency tests are carried out, to determine the ways of flow measuring for internal water turbines.
