Research And Application On Tool Of Intelligent Verification For Topology Model In Power Grid Dispatching

Electric power network topology analysis is the foundation of power flow calculation and power grid safety analysis and other function module in the energy management system (EMS) and distribution network automation management system (DMS), the veracity of power grid topology analysis results directly affect the use effect of these application software.Since the existing power grid scale is increasingly huge, and the structure is increasingly complex, the modeling work of the EMS of power system is very complicated in artificial way, there are the existing phenomena of connection relations error or incomplete between network electrical equipment components of grid model often due to personnel operating errors, which has affected the accuracy of grid topology analysis results to a certain extent. In response to this problem, with the general principles of power grid design as a starting point, based on power system topological representation method, this paper according to the general naming rules and their relations of relevant equipment components describing topological relations in the power grid, and using semantic recognition technology, the names of electric equipment in the power grid mode are analyzed based on voltage level, the substation, the electrical equipment types related properties step by step, so electrical equipment attribute is extended; Through Maximum Matching (MM) between the related properties of the electrical equipments, the system of topology analysis intelligent verification is developed with the function of automatic extension and modify for power grid model. The system has been used in power grid reactive power optimization system in a certain area in Hainan, the operation practice proved the effectiveness and practicability of the system.
