Embodiment Construction

[0058] The principles and features of the present invention will be 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.

[0059] In the power communication network environment, the problem of selecting the business security link of the power communication network refers to that, in order to avoid the global intensive risk distribution, in the case of ensuring the safety and reliability of the whole network, when selecting the business security link, according to the degree of risk It is different to evenly distribute services to the entire communication network to maintain the global risk balance of the network. Such as figure 2 As shown, it is a business distribution diagram of the power communication network, which can be expressed as G, G represents a weighted graph, where V represents a set of vertices, and E represents a set ...

Abstract

The invention discloses an electric power communication network safety link selection method and system, which relate to the field of intelligent power grids. The method comprises the following stepsof: inputting electric power communication services into a preset service importance evaluation and sorting model constructed according to a fuzzy analytic hierarchy process to obtain service importance and a service importance sequence of each service, and solving a preset service safety link selection model containing the service importance through a preset safety link selection algorithm and the service importance sequence of each service to obtain an optimal safety link. According to the optimal safety link configured by the scheme, the global risk balance degree of the electric power communication network can be effectively reduced, the transmission time delay is reduced, and the link calculation time is shortened.

Description

technical field [0001] The invention relates to the field of smart grids, in particular to a method and system for selecting a safe link of a power communication network. Background technique [0002] With the rapid development of my country's smart grid, the power communication network has been continuously extended, and its coverage has been widely used in the key links of power grid operation, such as generation, transmission, transformation, distribution, use, and dispatching, forming a network that is closely related to the daily production and operation of power. , maintenance and management of the closely related whole-process and whole-network power communication network, which is gradually transforming into a power market and a whole-process model of power production and operation centered on providing data transmission services and adapting to diversified communication methods and business functions. But then, the new operation and management mode of the power commu...
