摘要
目前对调压室水位波动的研究主要有图解法和数值计算。尚未看到考虑阻力项后调压室水位波动随时间变化的显函数计算方法。本文从调压室的基本微分方程出发 ,采用泰勒级数展开式推导了阻抗式和简单式调压室甩荷时水位波动的显式计算方法。运用这种方法不仅可以计算调压室水位波动的过程 。
In recent years, the methods for calculating surges in surge tanks mainly consist of chart method and numerical simulation method. The explicit method for calculating surges in the surge tanks concerning the resistance item has not been seen. The explicit method for calculating surges in throttled surge tank and simple tank following load rejection has been derived by use of Thaler Series Expansion from the basic formulation of surge tank. Not only the procession of the fluctuation of the water level in the surge tank, but also the first and the second surges in the surge tank can be calculated.
