With the regulation graph in the form of regulation surface adopted and with runoffs between adjacent intervals taken as linearly dependent as well as by taking the hydrology prediction into consideration, a mathematical model of optimal reservoir dispatching is established. The method presented has been used to work out an optimum regulation scheme for a hydropower station in Hunan Province of China and it has been found that the scheme is far superior economically to conventional ones ever used.

文中建立了水库优化调度数学模型,其特点是采用调度面形式的调度图,同时考虑了时段之间迳流的相关关系和水文预报的应用.用本文提出的方法为拓溪水电站制定了优化调度图,取得了显著效益.

In the problems of optimization of a long-term regulating storage reservoir of a hydropower station, the Marcovian decision programming is often used to find the optimal policy of maximizing the average expected annual electric energy. However, in the majority of cases, it does not satisfy the reliability requirement of electric generation.

在长期调节水电站的水库优化调度中,一般采用马氏决策规划寻求平均年期望发电量达到最大的最优策略。但是,在极大多数情况下,这种策略往往并不能满足发电保证率的条件。 本文首先叙述了在相邻时段径流相关和面临时段径流不能予报的条件下,应用马氏决策规划的一般方法。然后,根据水电站保证率的含义,给出其概率形式的定义,从而把问题归结为随机约束下的马氏决策规划。 我们对应用惩罚方法求解这一问题进行了研究,对特定的罚函数得到了若干有用的性质。最后,简要地给出某水电站水库的一些实际计算结果。

In the management of a hydropower station reservoir system, the Markov decision progyamming is often used to determine the optimal policy which maximizes the expected annual electric energy production over an infinite time horizon. However, it hardly ensures the so-called reliability of the system. In this paper, the completely ergodic Markov chain with rewards is considered.

In the management of a hydropower station reservoir system, the Markov decision progyamming is often used to determine the optimal policy which maximizes the expected annual electric energy production over an infinite time horizon. However, it hardly ensures the so-called reliability of the system. In this paper, the completely ergodic Markov chain with rewards is considered. A definition of reliability in probability form is given, based on the frequency form as used in engineering. The problem is thus reduced to a Markov decision programming subject to a stochastic constraint. An algorithm based upon the penalty factor method is also developed. Several properties of interest are deduced. Finally, the method is generalized to the periodic case for the original management problem.

在水电站水库优化调度中,常用马氏决策规划寻求使平均年期望发电量达到最大的最优策略。但是这种策略往往不能满足所谓保证率的要求。本文对带有报酬的完全各态历经的马氏链,根据工程上使用的频率形式保证率的定义,给出它的概率形式的定义。从而把问题归结为一种随机性约束下的马氏决策规划。对于用罚因子法求解这一问题进行了研究,证明该方法的一些在实用上有价值的性质。最后推广到水库优化调度所需要的周期性的情况。
