The energy center is the core device and power source of the production enterprise. It provides various indexes of chilled water, hot water and compressed air for the production process. It is the basis of stable production. Its automatic control system needs to fully consider the system stability and meet the energy saving requirements.

Power plant involves many subsystems, which need to communicate with each subsystem for interactive data, mainly including: water chiller, boiler system, dosing system, degassing system, constant pressure system, etc.
