Problems solved by technology
This greatly increases the consumption of server memory resources, and preloading topology data will cause the service to start up for a long time, often reaching several hours, and the operation and maintenance of the system is inconvenient
In addition, due to the high update frequency of the distribution network, the topology data is usually updated every day, so the real-time update problem of the memory topology network must be considered, which greatly increases the complexity of data processing, and easily causes data inconsistency, which in turn affects the topology analysis. accuracy

The invention discloses a method and a system for dynamically loading topological data of a power distribution network. The method comprises the following steps: acquiring initial equipment and topological analysis requirements of topological analysis of the power distribution network; determining initial data blocks corresponding to the initial equipment according to a pre-constructed feeder line topology set or station building topology set; and according to the topology analysis requirements, carrying out data loading on the initial data blocks, querying the directly connected data blocks according to an inter-block connection device object in the initial data blocks and carrying out data loading, and / or querying the indirectly connected data blocks through the directly connected data blocks and carrying out data loading. The method has the advantages that the overall loading of feeder line / station building topological data can be conveniently realized, and the topological data reading speed is greatly improved.
Description
technical field [0001] The invention relates to a dynamic loading method and system for distribution network topology data, and belongs to the technical field of distribution network topology analysis. Background technique [0002] The topological connection relationship data of power grid equipment is the core of power grid resource information, and many business activities of power grid management are closely related to it. Distribution network topology analysis based on equipment topology data is the basis of distribution network system simulation and analysis calculation. [0003] At present, the distribution network topology data model is usually constructed based on the CIM topology model in the IEC 61970 standard or the SG-CIM topology model formulated by the State Grid Corporation of China. Traditional topology data storage methods generally use databases for structured storage, that is, construct terminal tables and connection node tables in the database to express...
