| 摘 要： | 针对多决策变量复杂非线性系统优化问题,引入基于DPSA的传统分解聚合模型进行并联泵站叶片全调节优化运行研究.首先将大系统分解为若干个子系统,采用DPSA法对各子系统进行优化;再以各子系统分配水量作为关联变量将各子系统回归方程进行聚合,并由聚合模型确定整个系统的最优解;最后通过关联变量将系统最优解反馈到各子系统,从而得到各子系统相应优化调度过程.通过在江都并联泵站叶片全调节优化中的应用,实现了系统总费用最小时的优化调度过程,确定了各站各时段开机台数及叶片角度的最优组合方案,表明了方法的可行性.同时以单位提水费用为指标,按考虑峰谷电价与不考虑两种情况,分析了江都站不同日均扬程、不同运行负荷下,叶片全调节相对定角恒速的优化运行效果,其中考虑峰谷电价节省费用较多,在满负荷、80%负荷6、0%负荷运行情况下,不同日均扬程单位费用节省率均值分别为7.52%2,2.19%,25.89%.

| Abstract: | According to the complex nonlinear optimization problem of multiple decision variables,the traditional decomposition-amalgamation method based on dynamic programming successive approxi-mation(DPSA) was applied in the optimization of parallel operation of the blade-adjustable pumps in a pumping station.Firstly,the large-scale system was decomposed into a series of subsystems,for each decomposed subsystem,DPSA was applied respectively in order to search for the relationship between its own optimization target... |
