Abstract: The development and utilization of multi-energy coupling platform has been completed by the software of Siemens S7-200 and configuration software WinCC. PLC of Siemens is used to collect temperature, flow rate, quantity of heat, power, etc. and calculate the COP of heat pump and the system. The detecting system is composed of the slave computer PLC and the host computer WinCC. The real-time monitoring and control function are realizedbythis system.And six operational modes of the solar-ground source heat pump system are designedaccording to different external conditions, which is an effective way to make up the shortcomings of the solar energy and GSHP (Ground Source Heat Pump) individually.

Keywords: PLC, WinCC, Monitoring system, Operational mode
