目前,国内、外计算机组甩负荷过渡过程最大速率升高的近似公式不下几十种,计算方法和表达方式都很不统一,而且计算结果大都比实测值大很多,例如过去我国广泛采用的摩根史密斯(S·M·S)公式和列宁格勒金属工厂(λ·M·3)公式,当管道特性系数6>0.4(对前者),或导叶关闭时间Ts与机组加速时间常数Ta的比值Ts/Ta≥1.5(对后者)时,其相对误差一般在50%以上,使工程建设造成不必要的浪费。苏联1975年出版的“水力
At present, there are no more than a few approximate formulas for the maximum rate of load transfer in domestic and overseas computer groups. The calculation methods and expressions are not uniform, and most of the calculated results are much larger than the measured values. For example, in the past, Morgan Smith and Leningrad metal mills (λ · M · 3) formula, when the pipeline characteristic coefficient 6> 0.4 (for the former), or the ratio of the vane closing time Ts and the unit accelerating time constant Ta Ts / Ta ≥ 1.5 (for the latter), the relative error is generally above 50%, causing unnecessary waste of construction.
