污水处理泵站智能节能控制方法研究与仿真

Sewage Pumping Station Intelligent Energy-Saving Control Method and Simulation

研究的污水处理降低泵站运行能耗问题。污水排放量随着季节和时段变化非常大,大范围、高强度的降雨会让排水量在短时间内产生较大幅度的变化,短时强度变化,使系统存在非线性,造成提升泵工作功率和时间模型不稳定,传统的调度方法多是采用调度模型完成调度,调度的不稳定会造成提升泵频繁的启停,消耗大量电能。提出一种利用扩展时间自动机的泵站节能控制算法,通过集水井液位变化控制泵站的工作状态。对传统的时间自动机进行语义扩展,可包含连续变量和变量约束,并组成扩展时间自动机ETA,使用ETA对泵站控制进行建模和验证;实验表明,改进方法能减少提升泵频繁启停,可降低泵能耗。

Research low energy operation of sewage pumping station. Wastewater discharge process is complex and has many changes. This paper put forward a pump station energy saving control algorithm based on extended time automaton. According to the changes in collector well water level, the working state of the pumping station was controlled. The semantic of traditional time automaton was expanded to ETA time automation. The experiment results show that the improved algorithm can reduce energy consumption.
