摘要
针对江都四站泵站单机组变角运行优化问题,提出了解决该问题的数学模型及求解方法。在优化算法的外部提前计算出了各时段满足功率约束的叶片角,降低了优化计算的复杂度。通过实验比较,得出了动态惩罚函数法能更有效地处理提水量约束条件。将动态惩罚函数遗传算法的计算结果和算法运行时间分别与动态规划法、枚举法进行对比,3种方法按照总费用从小到大排序依次是:枚举法、动态惩罚函数遗传算法、动态规划法,3种优化方法相互之间的单位提水费用偏差率均小于0.2%。运算时间方面,动态惩罚函数遗传算法和动态规划法几乎相同,枚举法耗时接近前2种方法的6倍。综合比较,动态惩罚函数遗传算法更适合江都四站泵站单机组变角运行优化问题的计算。
Aiming at the optimization problem of single-unit variable angle operation of Jiangdu NO.4 pumping station, a mathematical model and solving method for solving this problem were proposed. The blade angle that satisfied the power constraint in each period was calculated in advance of the optimization algorithm, which reduced the complexity of the optimization calculation. Through experiment comparison, the dynamic penalty function method could be more effective in treatment of water extraction constraint. Comparing the result and operation time of dynamic penalty function GA with dynamic programming and enumeration method, from small to large sorting of three methods in accordance with total cost was enumeration method, dynamic penalty function GA, dynamic programming, the deviation rate of the unit water charge was all less than 0.2%. In the aspect of operation time, the dynamic penalty function GA and dynamic programming cost almost the same, and the enumeration methods was 6 times as long as other two methods. Compared comprehensively, the dynamic penalty function GA was more suitable for solving the problem of optimal operation of single adjustable-blade pump unit in Jiangdu NO.4 pumping station.
