Problems solved by technology

[0003] In order to implement static security analysis using the N-1 security criterion, brute force enumeration can be used to disconnect each node of the power system in turn and perform security analysis on the power system. The whole process requires a lot of time and computing resources
For example, when there are 3,000 nodes in the power system, each of the 3,000 nodes needs to be disconnected in turn, and the safety analysis of the power system needs to be performed at least 3,000 times, which consumes a lot of time and computing resources. Take at least 70 minutes if possible

Abstract

The invention provides an analysis method and device for a power system and equipment thereof. The method comprises the steps of acquiring a first power plan; obtaining a first power grid node layoutaccording to the first power plan; according to the first power grid node layout and the label value of the first power grid node layout, training a corresponding relation between power grid characteristics and characteristic values; wherein the corresponding relationship is used for analyzing the state of the power system. Through the technical scheme of the invention, rapid static safety analysis of the power system can be carried out, and power planning and scheduling are supported. The time for safety analysis can be saved, and computing resources for safety analysis are saved.

Description

Technical field [0001] This application relates to the field of electric power, in particular to a power system analysis method, device and equipment. Background technique [0002] In the power system, static safety analysis is usually required to evaluate the safety and stability of the power system. The N-1 safety criterion is an important means of static safety analysis. The realization principle is: when any node of the N nodes of the power system is disconnected due to a fault, the power system can operate stably and supply power normally. [0003] In order to implement static security analysis using N-1 security criteria, brute force enumeration can be used to disconnect each node of the power system in turn, and perform security analysis on the power system. The entire process requires a lot of time and computing resources. For example, when there are 3000 nodes in the power system, it is necessary to disconnect each of these 3000 nodes in turn, and perform safety analysis ...
