Embodiment Construction

[0076] An embodiment of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0077] The method for evaluating the emergency capacity of the urban power grid in this embodiment, such as figure 1 As shown, it starts from step S201.

[0078] In step 202, an evaluation index system for urban power grid emergency response capability is established;

[0079] The urban power grid emergency capacity evaluation index system established in this implementation mode, such as figure 2 As shown, the evaluation index of urban power grid emergency capacity in this implementation mode is composed of the first-level urban power grid emergency capacity evaluation index and the second-level urban power grid emergency capacity evaluation index; the first-level urban power grid emergency capacity evaluation index in this embodiment is referred to as the first-level index , which is composed of the evaluation index of intrinsic safety ca...

Abstract

The invention discloses an urban power grid emergency capacity assessment method and belongs to the technical field of electrical power system emergency. The urban power grid emergency capacity assessment method comprises the steps of utilizing an anti-entropy weight method to calculate objective weights of emergency capacity assessment indexes of all levels of urban power grids, utilizing a G1 method to calculate subjective weights of the emergency capacity assessment indexes of all levels of urban power grids on the basis, and linearly combining the subjective weights and the objective weights to obtain combined weights of the emergency capacity assessment indexes of all levels of urban power grids, wherein the disadvantage of the limitation of solely subjective weight calculation or solely objective weight calculation is successfully overcome, and the accuracy of the weight calculation is improved; utilizing fuzzy comprehensive judgment to perform initial judgment on the urban power grid emergency capacity, utilizing a grey relational degree method to correct an initial judgment result, performing final judgment on the urban power grid emergency capacity to confirm the urban power grid emergency capacity level. The urban power grid emergency capacity assessment method well masters the situation of the urban power grid emergency capacity and has important practical significance on perfection of the urban emergency capacity promoting work.

Description

technical field [0001] The invention belongs to the technical field of electric power system emergency response, and in particular relates to a method for evaluating emergency capacity of an urban power grid. Background technique [0002] Driven by the rapid development of the current power industry and the reform mechanism, various high-risk events and emergencies inside and outside the power system occur from time to time, and the security of the power grid is always facing serious threats. Due to the lack of effective assessment, they cannot fully understand their own emergency response capabilities, which has become a major obstacle to improving emergency response work. Therefore, it is imminent to evaluate and improve the power grid emergency response capability. Compared with rural areas, cities have higher population density and more production activities, and as my country's urbanization continues to spread, its demand for electric energy is also deepening. Therefo...
