摘要
Abstract
This paper examines the measurement of pressure fluctuations in the development of pump turbine models when the turbine is operating under no-load conditions.Through model testing,parameters such as guide vane opening,torque,and cavitation coefficient were analyzed,along with the impact of their measurement methods on results obtained during no-load operation.Additionally,targeted methods to enhance measurement accuracy were proposed.Through the hydraulic R&D testing of a high-head pumped-storage unit project,the method for testing pressure fluctuations in the pump turbine under no-load conditions was improved,measurement accuracy during the model tests was enhanced,and errors in no-load pressure fluctuation tests were reduced.The results indicated that the tests achieved favorable outcomes.关键词
