摘　　要：导叶漏水量是评价水轮发电机组品质和状态的重要指标之一,其测量方法应结合电站实际情况合理选择。利用超声波测流法操作简便、测量时间短、测量精度高等优点,在某电站用超声波流量计开展了导叶漏水量的测量工作,试验结果基本满意,可为其它水电站导叶漏水量的测量提供参考。The amount of leakage of guide vanes is one of the important indexes to evaluate the quality and status of hydro-generating units.The measurement method should be reasonably selected according to the actual situation of power station.The means of ultrasonic flow measurement has the characteristics of simple operation,short measurement time and high precision,and in this paper the ultrasonic flowmeter was applied to measure the leakage of the guide vanes in a power plant.The results were satisfactory and can provide reference for the measurement of the leakage of the guide vanes other hydropower stations.
