| 摘 要： | 为使离心式注水泵站运行组合更为合理,降低离心式注水泵站的能耗,研究了以功率最低为目标函数的离心式注水泵站优化问题,并得到了该优化问题的求解流程,且寻优结果包括各泵串并联方式以及各泵对应的转速.据以上研究内容,编制了离心式注水泵站优化软件,并针对某一油田注水泵站测试了该软件,所得结果为该注水泵站提供了改造方案,该泵站在此方案运行,具有功率最低的优点.研究结果表明:在某些工况下,离心泵的串并联及调速能使尽可能多的离心泵工作在高效区;利用完全枚举法进行针对某一工况下的泵组合寻优时,能将离散的泵组合寻优问题转化为方便求解的非线性规划问题,该非线性规划问题可利用Matlab中的fimicon函数求解.研究结果可为针对某一注水泵站的运行优化或改造提供参考方案.

| Abstract: | In order to make the operation combination of centrifugal water injection pump station more reasonable and reduce its energy consumption, the operation of centrifugal water injection pump station was optimized by minimizing the objective function of consumed power in the paper. A solution procedure forthis optimization problem was obtained, and the optimized results include series-parallel connection modes of various pumps and rotative speed of each pump.According to the result content above, an operation optimization software of centrifugal water injection pump station was composed and applied to the water injection pump station in a specific oil field. The optimized mode will serve as an update operation mode of the station.In this mode, the pump consumed power is in the minimum. The results show that the series-parallel connection and speed regulation of centrifugal pumps can allow them as many as possible to run in the high efficiency zone under certain operating conditions.When the complete enumeration method is used to search the optimum operation combination at a duty point, the discrete optimization problem of pump combination can be transformed into a convenient non-linear programming problem.Fortunately, this nonlinear programming problem can be solved by fimicon function in Matlab. The results can provide a reference for operation optimization or technical transformation of the water injection pump station. |
