| 摘 要： | 针对典型调压室水力系统,建立了具有随机初始条件的涌波分析随机模型,并根据调压室水位波动特点,去掉了随机模型中的绝对值;利用泰勒级数展开式推导了水轮机瞬时全部甩荷时调压室中水位第1次向上波动时的水位随时间的随机解过程,并由此给出了解过程的密度函数公式和涌波均值的最大值的显式计算公式.

| Abstract: | A stochastic model with stochastically initial conditions for surge calculation was developed for a typical hydraulic system of a surge tank. According to the characteristics of surges, the absolute symbol was removed from the stochastic model. The random process for the first upward fluctuation of water level in the surge tank at all load rejection was derived by means of Taylor series expansion, and the density function of the solution and the explicit formula for the maximum of mean surges were given. |
