为更加科学合理地开展泵站优化运行综合评价, 采用主成分分析法对评价指标进行优选。在构建衡量泵站优 化运行特征指标集的基础上, 借助遗传投影寻踪模型( GA2 PP) 将高维数据投影到低维子空间上, 寻求最佳投影方 向, 对最佳投影方向与评价指标的线性投影进行计算得到投影指标值, 作为判断泵站优化运行优劣程度的依据并对 其进行统一评价, 进一步提升泵站经济运行能力以及泵站系统联合优化调度综合水平。以淮安四站为例, 开展单机 组日优化运行评价, 结果表明: GA2PP 模型能在很大程度上避免传统评判中人为赋权的干扰, 得到的最优运行方案 不仅运行成本低且更符合泵站日常运行需求, 评价结果更为准确客观。

In o rder to unfold the comprehensiv e assessment o f pump operation o ptimizat ion mo re scientifically and reasonably, the pr incipa l component analy sis ( PCA) w as applied to the optimal selection o f evaluatio n indexes. On the basis o f co nstr ucting the char acter istic index set of pump operat ion o pt imization, the high2dimensional data w ere pro jected onto the low2dimensio nal space using the Genetic Pro jectio n Pur suit Model ( GA2PP) to det ermine the o ptimal pr ojectio n directio n. The pro jectio n index value was obtained f rom the calculat ion of the optimal project ion directio n and linear pro jectio n o f ev aluatio n indexes, w hich can syn2 thesize the v ir tues or defects deg ree of pump o per atio n o pt imization and conduct a unifo rm evaluation, and further pr omo te the eco nomical operatio n capacity of pump station and comprehensiv e level of united optimal o perat ion o f pumping station system. A calculatio n ex ample for the daily optimal operation o f the No. 4 H uai. an pumping station w as conducted. T he results show ed that the appro ach can avo id the a rtificial distur bance o f t raditio nal metho d in the weight value identif ication to the max imum ex2 tent and the evaluat ion results of pr ojectio n pursuit not o nly have low cost but also are suitable fo r practical operation.
