 In this paper, applying hierarchical control theory of large systems, hydroelectric reservoirs in series are decomposed along axes of time and space and then a decomposedcoordinated model of three level structrue for optimizing dispatching of them is established and solved. Finally, a practical example is given.Applying this model can cut down demensions of problem notably, therefore, it is possible to calculate it with a microcomputer, especially with microcomputers running jointly. Thus, the theory... In this paper, applying hierarchical control theory of large systems, hydroelectric reservoirs in series are decomposed along axes of time and space and then a decomposedcoordinated model of three level structrue for optimizing dispatching of them is established and solved. Finally, a practical example is given.Applying this model can cut down demensions of problem notably, therefore, it is possible to calculate it with a microcomputer, especially with microcomputers running jointly. Thus, the theory and method is valid for real time opertion of reservoirs.  本文应用大系统递阶控制理论,对入流为确定的梯级水库群进行长期最优调度,建立了大系统递阶控制模型。该模型把水库群在空间和时间上进行分解,建立了塔姆拉三级分解协调结构。第一级(单一时段)最优化问题用0.618法求解。第二、第三级协调器采用混合法进行协调。最后对一实例在IBMPC88微机上完成计算,得出了满意的结果。实践证明该模型占用计算机内存少,省机时,并用微机可解决水库群优化调度问题。  The hydro plant with compensating reservoir is running jointly with the upstream hydro plant.However, the plant with compensating reservoir has smaller caP8city and can not produce enough amount of electricity. In construction it has larger amount of engineering quantity and higher investment. Hence in economic analysis the question is how to evaluate its benefit objectively, especially when it is on the navigable river. In the text is given an engineering example to discuss the question and three ways... The hydro plant with compensating reservoir is running jointly with the upstream hydro plant.However, the plant with compensating reservoir has smaller caP8city and can not produce enough amount of electricity. In construction it has larger amount of engineering quantity and higher investment. Hence in economic analysis the question is how to evaluate its benefit objectively, especially when it is on the navigable river. In the text is given an engineering example to discuss the question and three ways of reducing price of power supplied to network during the period of paying off loans are pro[psed.  具有反调节性能的水电站与其上游水电站是一组联合运行的水电站。由于反调节电站工程量大、投资较高，且本身电量不多，因而在对其进行财务分析时，还贷期上网电价较高。士。何全面客观地评价反调节水电站及其对上游水电站所带来的效益，特别是在通航河流上修建反调节电站，对其财务评价应如何反映？本文对此进行了探索，并给出一个工程实例加以说明；还提出了降低还贷期上网电价的３个途径。  A general processing simulation system for MOCVD is presented. This software package includes three subsystems: reactor fluid mechanics simulation subsystem, reaction thermodynamic simulation subsystem, deposition kinetics simulation subsystem. These subsystems can run independently for different aims, also can run jointly for complete simulation of MOCVD.  报道一个 Ｍ Ｏ Ｃ Ｖ Ｄ 全方位综合工艺模拟系统． 该系统包含反应室气流流体力学模拟、化学反应热力学模拟和沉积过程动力学模拟等 ３ 个子系统， 它们可以独立运行， 也可以联合运行．   << 更多相关文摘
