(一)压力管道中的水锤过渡过程分析计算主要是利用原始资料应用公式计算设计所需的参数;水轮机开度变化时的水锤和机组甩负荷时的最大速率上升。分析法的优点是可以很快枣解且困难较少,但要求简化计算条件和限制所考虑的因素,也就是会降低成果的精度。为此,分析法计算可用于初步设计阶段;当用图解法、列表法或电子计算机进行全部计算时,不仅可用于初步确定参
(A) Analysis and calculation of water hammer transition process in pressure pipeline mainly use the formula of original data to calculate the required parameters for the design; the water hammer at turbine opening degree and the maximum rate at unit load rejection increase. The advantage of analytics is that it can be solved quickly and with less difficulty, but requires simplifying the computational conditions and limiting the factors under consideration, which can reduce the accuracy of the results. For this reason, the analytical calculation can be used in the preliminary design stage; when all calculations are performed by graphic method, list method or electronic computer, it can not only be used for preliminary determination of parameters
