Construction Of Middle-station Engineering Project Of Power Grid Resource Business Based On SG-CIM4.0 Model

There is no unified power grid resource management mode in the existing power system,and there is no unified storage,management and maintenance of equipment asset basic data.The production systems of various regions and departments are developed by different manufacturers in different periods,resulting in the inconsistency of basic production data,the emergence of data islands,and extremely high maintenance costs.In2013,based on the public information model(CIM),the According to the current situation of power grid operation and management,the power grid company puts forward the concept of sg-cim(stategrid CIM),which provides a unified specification for power grid modeling.In December 2019,the sg-cim model was updated and iterated to 4.0,cooperating with grid resource management,deeply implementing the company's strategic goal of building "an international leading energy Internet enterprise with Chinese characteristics",and accelerating the digitization of equipment management The work deployment of transformation and enabling power grid construction and operation.Based on sg-cim4.0 and IEC61968 / 61970 standards of State Grid Corporation of China,this paper completes the iterative improvement of data models of resources,assets,topology,graphics and users of various specialties.Meanwhile,it builds a grid resource business platform,integrates the data of grid equipment and topology scattered in various specialties,and realizes the unified standard,homologous maintenance and unified management of data from power supply,power grid to users To form a "power grid map",common business will be precipitated into grid equipment resource management,asset(physical)management,topology analysis and other shared services,to support the rapid and flexible construction of grid planning,production and maintenance,customer service and other businesses.Following the achievements of top-level design and centralized R &D of State Grid,we will steadily promote the deepening of distribution network side,service extension of main network side and data access,comprehensively deepen the construction of power grid resource business center,and support the transformation of the business center.
