摘要
结合某水电站的实际情况,采用通气孔法的测量方式,基于容积法的基本原理,分别分析、推导、比较了最小二乘法二次曲线拟合法、斜率法、切线斜率法三种不同导叶漏水量计算方法的优劣,给出了普遍适用的水电机组导叶漏水情况的评价指标。后续还会根据实际运用情况进一步探讨。
Considering the practical situation of a hydropower station,the vent-hole method is adopted to measure the water leakage of guide vanes.Based on the basic principles of the volume method,three calculation methods of the guide vane leakage,i.e.the least squire conic fitting method,gradient method,and tangent slope method,are deduced,analyzed and compared.A universally applicable evaluation index of the guide vane leakage is proposed,which will be further explored in the future according to actual application performance.
