Problems solved by technology

[0003] In related technologies, the risk assessment of the power communication network is carried out through the BP neural network algorithm. The training process of the BP neural network is to reduce the error energy function to a given accuracy. However, due to the high-dimensional complexity of the error function, the BP neural network The algorithm has the problems of slow error reduction, long adjustment time, slow convergence speed, and low precision, which has caused the problem of long process time and low precision in the risk assessment of the power communication network

Abstract

The invention discloses an electric power communication network risk assessment system, which includes a risk assessor and a plurality of electric power communication devices connected to the risk assessor through a network interface. The risk assessor comprises an electric power communication network evaluation index system generation module, an evaluation level system generation module, an index quantification module, an index weight calculation module, a membership degree matrix construction module, a fuzzy comprehensive evaluation result calculation module and a risk evaluation module. The electric power communication network risk assessment system of the invention can analyze various uncertain factors and indexes appearing in the risk evaluation process through the application of a fuzzy matrix and an analytic hierarchy process in the risk evaluation, and is high in evaluation speed and accuracy.

Description

technical field [0001] The invention relates to the technical field of power system security, in particular to a risk assessment system for a power communication network. Background technique [0002] The power communication network is a dedicated communication network for power system operation and management. It is an important infrastructure of the power system to ensure the safe and stable operation of the power system. It has obvious industry characteristics and special safety and reliability requirements. With the development of the power communication network, a large number of power system services need to be transmitted through the power communication network, the risk and failure of the power communication network have an increasingly serious impact on the power system, and the power system production department has more and more reliability requirements for the power communication network. The higher it is, this makes it important to carry out risk assessment on t...
