| 摘 要： | 对有复杂水力系统的大型水电厂，其厂内优化运行问题是一个非线性组合优化问题。在上游水位和负荷水平一定的情况下，如何确定最优的机组组合、给出最优机组功率和用水量的分配，是实际运行中难点所在。文中考虑了各种非线性特性和复杂的耦合关系，建立了该问题的数学模型，推导了最优性条件和广义等耗水微增原则，提出了相应的快速算法，可在线和离线应用。根据建议的方法开发了用于实际系统的软件，表明了所述方法的正确性和有效性。

| Abstract: | For a large hydro power plant with complex hydraulic system,its optimal operation is a complex nonlinear and combination optimization problem.When upstream water level and load level is constant,it is difficult to determine the optimal unit commitment,calculate the allocation of optimal unit power and water consumption in the process of actual operation.A model taking into account all kinds of nonlinear properties and complexly coupled relationships is set up.Optimal conditions and general equally increment... |
