动态规划法在火电厂并列运行给水泵优化运行中的运用

【摘要】 并列运行给水泵的优化运行是火电厂辅机优化运行的一个重要分支,为降低给水泵运行能耗,可选择合适的调度方式。运用优化理论提出了一种适用于电动给水泵的行之有效的调度方式——最佳调度法,并建立其通用数学模型。对于该问题的求解,运用了离散化动态规划法,在实际应用中能取得较满意的节能效果。更多还原

【Abstract】 The optimum operation of parallel feedwater pumps is one of the most important optimum operations about auxiliary units in thermal power plant. Appropriate dispatching modes can be chosen to reduce the energy consumption of feedwater pumps. This paper presents an effective dispatching mode, Optimum dispatching , which is suitable to electric pumps. And it applies the discrete dynamic programming theory to the solution of general mathematical model, which can gain remarkable economical effect through practice.更多还原
