Embodiment 1

[0062] The purpose of the present invention is to propose a service-oriented service centered on the distribution network business, based on a complete information model, ensuring data drive and availability, based on a graph database, and oriented to multi-model driving, multi-view synchronization, and multi-role collaboration. The design and construction method of the full information model of the distribution network, including the design of the bottom layer integrated protocol interface converter, the generation of the graph database for massive data in the middle layer, the procedural data verification mechanism, the construction of the full information data information service and the design of the overall holographic model architecture. Five parts . According to the bottom-up structure diagram of the data, the method is as follows figure 1 As shown, the flow chart of the construction method of the distribution network full information model is as follows figure 2 show...

Embodiment 2

[0077] The present invention provides a full information model design method oriented to the data requirements of the distribution network. By designing a full information model based on the graph database as the core, it provides a complete distribution network planning and design, infrastructure materials, operation and maintenance, and production scheduling. Power grid information service, realizing homogeneity of distribution network data. The graph database is similar to the distribution network data structure. The relationship between distribution network nodes is described as points, edges and their attributes. Each graph can be iteratively nested Figure, to achieve the description of the voltage network at all levels. Data addition, deletion, modification, and query can be easily realized without mechanisms such as indexing and caching, and data operations such as backup, tuning, and migration are also very efficient. The invention includes three key steps: a method fo...

Abstract

The invention relates to a power distribution network information model construction method and system. According to the method, an integrated protocol interface converter constructed in advance is utilized to complete collection of data for power distribution network equipment; external data supplementing service is started, and external data is collected; the data collected by the integrated protocol interface converter and the external data are used to construct a perfect information model; and the perfect information model is used to construct a graph database, and the graph database is subjected to data verification. Through the technical scheme, the problems that in the prior art, due to limitation of limited data sources, huge and scattered data sources cannot be mapped into complex calculation, analysis of a current power distribution network information model or a data architecture and big data has quite low reliability, a data system architecture and data service are prone to excessive collection, and availability is not high are solved.

Description

technical field [0001] The invention relates to a distribution network information model construction technology, in particular to a distribution network full information model construction method and system. Background technique [0002] With the continuous improvement of distribution network informatization and intelligent construction and interactive coordination, a large amount of high-dimensional, mixed and inaccurate distribution network data has been generated from the line equipment and user side, and the following problems exist: [0003] First, there are many data sources, and rich and effective data sources are the prerequisite for the development of big data. At present, the total amount of data resources and data increments generated by systems such as distribution automation, power consumption information collection, and production management systems are very large, and the amount of new data added each year is greater than 12%. For the existing limited data re...
