Abstract

The invention provides a method and system for quickly determining the stability of a power grid based on deep learning. The method comprises a step of obtaining plant station input amount data of a power grid, a step of inputting the plant station input amount data into a pre-established deep confidence network model to obtain a value corresponding to a stability judgment index of the power grid,and a step of judging the stability of power grid based on the stability judgment index value of the power grid, wherein the pre-established deep confidence network model comprises a hierarchical network structure constructed based on a power grid topology structure. According to the method and the system, the stability of the power grid is quickly judged by establishing the deep confidence network model, the quick calculation of the stability judgment index value of the power grid is achieved, and the effectiveness of the grid online security and stability analysis is improved.

Description

technical field [0001] The invention belongs to the technical field of large power grid stability and control, and specifically relates to a method and system for quickly determining the stability of a power grid based on deep learning. Background technique [0002] With the expansion of the grid scale, the security and stability of the grid is becoming more and more difficult to control. Many power grid failures that have occurred in the world show that the increase of transmission voltage level, the expansion of network scale and the increase of transmission capacity will increase the harm caused by grid failure, and the cause and process of failure will be more complicated. Carrying out comprehensive and detailed online monitoring, analysis and control of the operating grid to ensure the safety of power production, transmission and use is an urgent need of the power industry in various countries. [0003] The calculation speed is one of the core indicators that must be g...
