The most recent innovation in power plant design is the replacement of the conventional surge shaft by the air cushion surge chamber. Where the rock conditions are excellent and the rock-cover is thick enough, it can keep necessary support-measures to a minimum and reduces the cost of the project. However, its stable cross-sectional area is larger than that of conventional surge tank. In this paper, in order to reduce this area the double air cushion chamber system is proposed.

The most recent innovation in power plant design is the replacement of the conventional surge shaft by the air cushion surge chamber. Where the rock conditions are excellent and the rock-cover is thick enough, it can keep necessary support-measures to a minimum and reduces the cost of the project. However, its stable cross-sectional area is larger than that of conventional surge tank. In this paper, in order to reduce this area the double air cushion chamber system is proposed. The differential equations of oscillation are established. The critical conditions of oscillation stability and its generality are derived. It is indicated that an air cushion surge chamber, a conventional surge tank, conventional surge tank and an air cushion surge chamber system, double conventional surge tank system are all special cases of the double air cushion surge chamber. Their critical condition of stability under small oscillation is given in this paper. The influences of different factors on the oscillation stability are analyzed with an engineering example. Finally, the transient process in air cushion chambers power station system with governor is solved by computer method. The influences of gevernor parameters and cross-sectional area of surge chamber on the governing quality are also presented. The calcluation shows that the former is more sensitive than latter.

气压式调压室可以设置在覆盖深,岩性好的地段,其布置不受地形条件的影响,可以节省工程量,获得经济效益,国外有成功使用气压调压室而得到巨大经济效益的实例。气压式调压室的稳定断面较大。本文从实际情况出发,提出采用双气压式调压室,以减少单个调压室的水平横断面积。文中建立了双气压调压室的波动微分方程,论证了波动稳定的条件及其一般性。说明了上游双园筒式调压室系统,上游一个园筒式调压室与一个气压式调压室相串联的系统,上游单园筒式调压室,上游单气压式调压室诸情况均属本文特例,它们均临界稳定条件均包含在所导出的(13)式中,(13)式是托马条件的推广。还结合具体的算例讨论了影响波动稳定的各主要因素。指出:局部水头损失和调压井的位置对稳定区域和临界稳定断面的影响是重要的。本文还利用电子计算机方法给出了双气压式调压室、水轮机、调连器系统的调节过渡过程,并分析了调速器缓冲时间常数T_d,缓冲强度b_t以及调压井断面积对小幅度调节过渡过程的影响。计算机方法计算结果与临界稳定条件基本一致。

The optimal calculation on firm power of cascade hydro-power station system is a MaxMin problem with nonlinear constraints. The purpose of this paper is to present an efficient algorithm to solve the problem directly. In the last of this paper we calculate a practical example of optimizating the firm power of a hydropower station system which contains five hydropower stations. The result shows that the algorithm is efficient.

梯级水电站群保证出力优化计算问题是一个有非线性约束的maxmin问题max{M_f(X)|X∈G={X|g_j(x)≤0,j=1,…,N,X∈R~n}),其中M_f(X)=min{f_1(X),…,f_K(X)}。本文在文[1]的基础上,提出一个求解该问题的直接算法。所给出的算法保证了迭代序列{X~((i))_(i=1)~∞的可行性,即有{X~((i))_(i=1)~∞(?)G。本文最后计算了一个梯级水电站群(包含5个水电站)的保证出力优化的实例,计算结果表明该算法是有效的。
