Embodiment Construction

[0044] The technical solutions provided by the present invention will be described in detail below in combination with the accompanying drawings and in the form of specific embodiments.

[0045] The inventor noticed during the invention that:

[0046] After long-term observation and research, it is found that graph computing technology, as a data storage and computing processing technology that has developed rapidly in recent years, focuses on solving massive data storage and its internal dependencies. It can update the nodes, edges, attributes and other elements of the graph in real time, and can support Parallel computing on large scale data. In addition, the electrical topology has a natural connection with the graph data structure, and the electrical components and their connections correspond to the vertices and edges of the graph structure, respectively. Therefore, a graph model can be established from the topology of the power grid, and the connection between electrica...

Abstract

The invention provides a method and device for analyzing the outage range of a power distribution network. The method comprises the steps of extracting a data column from topology source data according to a data dictionary in a pre-established graph data model, importing the data column into the graph data model, and building a graph database; retrieving in the graph database according to a presetsearch terminating condition, and sequentially performing wide-depth diffusion analysis; and determining the power failure range according to a result retrieved and returned in the graph database. The analysis device comprises a database unit, a retrieval unit and a result processing unit. The technical scheme provided by the invention retrieves based on the path of edges in a graph and analyzesthe influence area of a fault electrical component, thereby accurately and efficiently processing large-scale fault data of the power distribution network, and providing technical support for outage emergency repair and power distribution network management.

Description

technical field [0001] The invention relates to a power outage management service of a distribution network and a method for quickly locating a power outage area, and specifically relates to an analysis method and an analysis device for a power outage range of a distribution network. Background technique [0002] The Outage Management System (OMS) is built on the distribution network safety monitoring and data acquisition system (DSCADA), automatic drawing / equipment management / geographic information system (AM / FM / GIS), power distribution equipment maintenance management system, fault repair response system On the basis of (TCM) and customer information management system (CIS), etc., the real-time information of distribution network operation, equipment maintenance information, user information and geographic information are comprehensively analyzed to determine the best blackout plan. [0003] The intelligent power consumption system monitors the dynamic process of productio...
