外文原文 Wincc in heating supply stapply stations Constant Pressure Monitoring System Application onstant voltage supply basic working principle System uses Automatic Frequency Control regulation or pump motor speed. Plus or minus pump.It is primarily by the Frequency Control System.PID regulator,pressure sensors,liquid level sensor power control circuits and other conponents.Host users control system or control board light over-the-counter transactions,buttons,switchto understand and control systen operation,Based on the PID control mode,the operator interface settings in water pressure,PLC to pressure settings and measured valucs for the deviation PID operation and regulation of distribution through inverter pump speed,so that water pressure was maintained at the set value. Systen hanlware configuration The system uses Siernens S7-200 PLC and its configuration software constitute a constant WinCC V6.0 Water pressure control system,water pressure monitoring process.Industroal Ethernct controller for PLC and the operator station computer communication betwween the Remote I/O network for the PLC and the operator station compuler communication betwween the Remote I/O network for the PLC controller and inverter,the soft starter of communication betwween equipment.PLC controller mainly used to monitor and control water and electricity systems.For1#-4#pressurized pump converter using the ABB Acs510-01-031A4 inverter,HMI operatostation selection DELL conputers,conputer,Industrial Ethernet server card Siemens conmmunications company CP1612.
