| Abstract: | The paper introduces closing law of global valve and guide vane of Huizhou pumped storage power plant,and it analyzes and gets rid of impact of acoustic resonance in piezometric tube in the process of load shedding test in order to reflect actual pressure fluctuation of units.The test show that the load shedding test of unit can well accord with simulation calculation,providing scientific basis for safe operation of dual-unit and quarter-unit load shedding. |
