With the rapid development of Energy Internet

power system and thermal system combines more and more closely. But there is an information island between different systems. In order to achieve multi-energy flow management

it is necessary to break the information island between the power system and the thermal system. Taking the steam heating system in industrial park for example

based on in-depth study of steam heating system in industrial park model and the mature experience of information exchange standardization of power system

classes and attributes of the steam heating system in industrial park are extended

and the topology model

the measurement model and the equipment model of the steam heating system in industrial park are described by using object-oriented modeling method of common information model. Finally

an example is given to verify the models.
