摘　　要：为提高旋流池控制系统稳定性,应用S7-300PLC作为系统主站,通过现场总线Profibus-DP与1个ET200分站及1个PP17建立通讯实现控制,通过MPI连接1台计算机操作员站,采用STEP7完成控制系统应用软件开发,应用SMC150软启动器,实现了1台软启动器挂接2台电机,泵的启动电流由原来直接启动的1 200 A降到800 A,减少了因速度突变而引起的电流过大和机械冲击,有利于延长电气和机械寿命。In order to improve the stability of the swirl pool control system, the S7-300PLC is used as the master system, the communication is established between ET200 stations and PP17 through the PROFIBUS-DP, the computer of the operator station is connected by MPI. The STEP7 software is applied to develop the control system. The SMC150 soft starter is applied to realize one soft starter connecting two motor＇ s function. The starting current of the pump is reduced to 800 A from above 1 200 A in original, and it is favorable for prolonging the life of electrical and mechanical equipments.
