Abstract:Comprehensive energy service is an important way to fundamentally change the structure, mode and mechanism of traditional energy. Combined with modern information technology, comprehensive energy services will form a new industrial form of "smart comprehensive energy services", which has been actively tried at home and abroad, but its application of information technology still does not cover the whole process of planning, design, construction and operation of comprehensive energy services, so it is impossible to achieve standardized sharing and in-depth application of data, and there is still a big gap with the real "smart" comprehensive energy services, And CIM (City Information Modeling) technology provides a solution for intelligent application of comprehensive energy services in the whole life cycle. This paper designs the platform architecture of the comprehensive energy service platform based on the CIM platform. Taking the actual project as an example, the CIM technology is applied throughout the whole life cycle of the comprehensive energy station, providing a positive exploration and attempt for the "smart" of comprehensive energy services.
