Embodiment Construction

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0025] In one or more embodiments of the invention, such as figure 1 As shown, a power system risk operation assessment method is provided, and the method is applied to the power system as an example for illustration, including the following steps:

[0026] Step S1, determine the working status of each node in the power system.

[0027] Specifically, the elements set at each node include at least one of transmission lines, transformers, generator sets, and buses; the working status of each node includes when the branch load value is greater than the preset maximum load threshold, the determined branch Overload state, the serious state of load loss determined when the degree value of branch loss load away from the p...

Abstract

The invention discloses an electric power system risk operation assessment method and device and computer equipment. The method comprises the steps that the working state of each node in an electric power system is determined; according to the working state of each node, when it is determined that the power system is in an accident state, influence factors are determined; the influence factors comprise a load level, a power flow variation, a node voltage, power loss and power distribution; and according to the risk operation probability of each influence factor, screening out a key influence factor from the influence factors, and carrying out risk operation assessment analysis according to the key influence factor. By implementing the method, the evaluation accuracy can be improved.

Description

technical field [0001] The present invention relates to the technical field of power system management, and more specifically, to a method, device and computer equipment for risk operation assessment of a power system. Background technique [0002] The power grid is mainly composed of substations and lines of various voltages. Its main function is to transform voltage transmission and distribution of electric energy. It is an important infrastructure for coordinating power development, distribution, transmission and consumption. The power grid is a part of the power system, in which the power system is a system composed of transmission, transformation and distribution lines connecting various power plants, substations and power users. At present, with the development of the economy, the power system is also in the process of continuous development, and it is extremely important to carry out effective risk operation assessment of the power system. At present, operation and m...
