摘　　要：水轮机导叶漏水率和效率是评价水电机组运转性能的两个重要的指标。介绍了目前应用较为广泛的导叶漏水率及效率试验的试验原理及方法,根据国标要求,针对试验机组提出最优试验方法,并根据试验数据拟合性能曲线,与预期运转曲线进行对比,明确了机组最优效率运行工况区域,并根据完整的试验案例为类似机组提供参考和依据。Guide vane leakage rate and turbine efficiency are two important indexes to evaluate the operation performance of hydropower unites. First introduces the test principle and methods of guide vane leakage rate and turbine efficiency test which are used widely. According to the requirements of national standard, the optimal test method is proposed for the test unit. The performance curve is fitted by using test data, and compared with the expected operating curve,the optimal efficiency operating circumstance of the unit is clarified. Provide reference and basis for similar units based on a complete test case.
