变频恒压供水系统是目前较为常用的供水系统,其采用变频调速方式实现水泵启动运行控制,从而减弱启动过程的冲击,且具有高效节能等优点。分析了系统的节能原理,研究了水泵启动过程中电流的超调和调节时间问题,基于ANFIS方法建立了变频器参数中加速时间参数值、加减速曲线参数值和超调、调节时间综合对象的模型关系,并借助PSO寻找最优解,实现了超调值小和调节时间短的优势组合下的变频器参数选择。以三菱变频器为例的仿真验证了方法的有效性,对用户使用变频器具有指导意义。
Frequency conversion constant pressure water supply system is the more commonly used water supply system, which uses frequency control method to achieve pump start-up operation control, thereby weakening the impact of the start-up process, and has the advantages of high efficiency and energy saving. The energy saving principle of the system is analyzed. The current overshoot and adjustment time of the pump are studied. Based on the ANFIS method, the parameters of the acceleration time parameter, the acceleration and deceleration curve parameter value and overshoot and adjustment time comprehensive object model Relationship and PSO to find the optimal solution to achieve a small overshoot and adjust the time advantages of a combination of frequency converter under the parameter selection. The simulation with the example of Mitsubishi inverter validates the validity of the method, which is of guiding significance for users to use the inverter.
