摘要
针对当今泵房工频恒压供水中电机启动对电网冲击大、供水压力不稳定的问题,设计了基于模糊参数自适应PID算法的电机恒压变频调速系统。本设计把PID控制与模糊控制结合在一起,水压传感器周期性检测供水管道压力,并将该压力值传输给控制芯片进行数据解析、执行模糊参数自适应PID算法程序,实现对PID 3个参数的实时修改,并将其结果作为变频器的总给定,实现了电机平稳启动与调速,降低了对电网的冲击,同时可根据用户需求实时改变供水流量。实际测试表明,所开发的系统实现了对泵房电机的变频调速,解决了工频供水方式电机启动对电网的冲击和供水水压不稳定问题。
Aiming at the problem that the motor starting in the pump room power frequency constant pressure water supply has great impact on the power grid and unstable water supply pressure, this paper designs a motor constant pressure frequency conversation timing system based on fuzzy PID parameter adaptivea lgorithm. This design combines PID control with fuzzy control, the water pressure sensor periodically detects the water supply pipeline pressure and transmits the pressure value to the control chip for data analysis and executing the fuzzy PID parameter adaptive algorithm program, it realizes the real-time modification of the three parameters of the PID. And the result is taken as the total given of the frequency converter, which realizes the smooth start and speed regulation of the motor, reduces the impact on the power grid, and can change the water supply flow in real time according to the users′ needs. The actual test shows that the developed system realizes the frequency conversion speed regulation of the pump house motor, solves the impact problem of the power frequency water supply mode motor starting on the power grid and the water supply pressure is unstable.
