轴流泵站经济运行方案的确定

Determination of economical operation program at draining pump station

轴流泵站建成后,灌排区域内作物组成、水文、气象等因素将发生变化,引起泵站进出水池水位、泵站扬程和流量发生变化,致使泵站运行效率低,能源消耗高.为保证泵站在原有设备的条件下经济合理地运行,达到提高泵站效率,降低能源消耗,减少运行费用的目的,提供了根据泵站的提水流量、进出水池水位和泵站扬程的变化,通过调节轴流泵的叶片安装角度,来提高泵站效率和降低能源消耗的技术措施,给出了用系统分析的方法确定轴流泵经济运行方案的数学模型、约束条件和求解方法.通过多座泵站的应用,并经泵站测试,泵站效率已得到提高,取得了良好的效果.为泵站的经济运行提供了依据.

After an axial-flow pump station is completed, the water levels of inlet and outlet sumps, head of pump station and capacity of pump station will all change with changes in the irrigation and drainage area, cropping pattern, hydrological and meteorology effects, resulting in low efficiency and high energy consumption. The keep the pump stastion running at economic condition a mathematical model and restraining condition based on system analysis and the solving methods are given for determining the economical operation alternative. By applying the model to reality, the efficiency of pump station is improved.
