Problems solved by technology

This leads to more and more complex queries in the system based on grid graphs, and slower and slower query speeds; at the same time, it also leads to the lack of self-computing capabilities of grid data, making the grid's ability to analyze and implement decisions in real time seriously insufficient
[0003] The above-mentioned existing problems not only make the work of dispatchers more and more heavy, but also lead to weak security defense capabilities of the power grid, which easily lead to power outages
Especially for the existing power grid risk identification, a large amount of data needs to be provided, and there are problems such as poor data correlation and long query time

Abstract

The invention discloses a power dispatching method and system based on a graph model, and relates to the technical field of power dispatching, and the method comprises the steps of: acquiring a sample data set; constructing a graph model according to the sample data set; and acquiring a query request of a user, conducting query in the graph model according to the query request, and returning a query result, which comprises a risk line segment and a risk plant station. According to the method, the data among the stations are acquired based on the power system, the data of the stations and the line data are associated by constructing the graph model, and the power grid risk caused by the fault of one or more lines can be quickly identified, so that the dispatching efficiency of the power system is improved, the insight in a power grid security defense mechanism is improved, and the power grid operation is safer, more reliable and more intelligent.

Description

technical field [0001] The invention relates to the technical field of power dispatching, in particular to a graph model-based power dispatching method and system. Background technique [0002] At present, the power grid production system only achieves simple collection and storage of relevant data, and lacks the correlation between power grid data. This leads to more and more complex queries in the system based on the power grid map, and the query speed is getting slower and slower; at the same time, this also leads to the lack of self-computing capabilities of the power grid data, making the real-time analysis and decision-making capabilities of the power grid seriously insufficient. [0003] The above-mentioned existing problems not only make the dispatcher's work more and more onerous, but also lead to weak power grid security defense capabilities, which easily lead to power outages. Especially for the existing power grid risk identification, a large amount of data need...
