Embodiment Construction

[0057] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0058] Such as figure 1 As shown, the method for minimizing the risk of grid cascading failures under multi-fire disasters includes the following steps:

[0059] Step 1. Obtain the failure probability of each transmission line according to the fire point distribution and transmission line distribution.

[0060] According to the distribution data of fire points, the geographical location of transmission lines and towers, etc., the failure probability of each transmission line is calculated. For the specific calculation method, refer to the patent "Method for Evaluating the Failure Probability of Transmission Lines Caused by Mountain Fire" (201310382753.9).

[0061] Step 2: Combining faults acco...

Abstract

The invention discloses a power grid cascading failure risk minimization disposal method and system under a multi-fire-point disaster, and the method comprises the steps: optimizing the deployment of fire extinguishing equipment, reducing the probability of an initial group failure, and adjusting the tide of a cascading failure power transmission line based on the deployment of the fire extinguishing equipment and the optimization of a power grid operation mode. Power grid operation mode adjustment and fire extinguishing measures are integrated to reduce cascading failure risks, and minimization of the power grid cascading failure risks under mountain fire disasters is achieved.

Description

technical field [0001] The invention relates to a method and system for minimizing the risk of power grid cascading failures under multi-fire point disasters, and belongs to the technical field of power system dispatching operation control. Background technique [0002] In recent years, frequent wildfires near transmission lines have caused multiple tripping and outage accidents including UHV AC and DC lines, seriously threatening the safe and stable operation of large power grids. During periods of high incidence of wildfires, such as during the Qingming Festival and the Spring Festival, the number of wildfires erupting near the transmission lines is as high as hundreds or even thousands, which can easily lead to simultaneous wildfire trip accidents on multiple lines, and may cause subsequent chain failures, which will seriously affect the power grid. Safe operation poses a serious threat. [0003] At present, there have been some studies on the risk assessment of cascadin...
