Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the present embodiment takes the technical solution as the premise, and provides a detailed implementation manner and a specific operation process, but the protection scope of the present invention is not limited to the present invention. Example.

[0033] like figure 1 As shown, a method for evaluating service operation quality of a power communication network includes the following steps:

[0034] S1. Establish the network topology of the power communication network:

[0035] According to the actual architecture and service distribution of the power communication network, a corresponding network model is constructed, and the network model includes network nodes, links and network bearer services, which are represented by Figure G as follows:

[0036] G = (V, E, S);

[0037] where V={v 1 ,v 2 ,...,v N } represents the node set in the power ...

Abstract

The invention discloses a method for evaluating the service operation quality of a power communication network. The method mainly includes: constructing a communication network model; calculating the probability of occurrence of different failure scenarios according to the Markov state transition theory; determining the factors to be considered according to the set confidence interval The number of failure scenarios; calculate the average service failure index and average service impact index under different failure scenarios according to the failure scenarios considered, and combine the failure probabilities of different scenarios to obtain the comprehensive service failure index and comprehensive service impact index of the entire network; by comparing different networks or Under different service distributions on the same network, the magnitude of the network-wide comprehensive service failure index and the network-wide comprehensive service impact index determines the quality of network service operation. The method of the invention can objectively reflect the business risk status of the power communication network, and involves low calculation complexity of the algorithm.

Description

technical field [0001] The invention relates to the technical field of electric power communication networks, in particular to a method for evaluating the service operation quality of electric power communication networks. Background technique [0002] The power communication network is the second physical network of the power system, one of the national dedicated communication networks, and an important infrastructure of the power system. The power communication network undertakes many businesses such as power production, management and enterprise informatization. It is the basis for the power grid to realize dispatch automation and management modernization. It is an important technical means to ensure power grid security and economic dispatch. It plays a very important role in the entire power system. effect. Under the background of smart grid and energy Internet, the scale of power communication network is getting bigger and bigger, and it undertakes more and more busine...
