Electric power communication network operation fault measuring method

Abstract

The invention provides an electric power communication network operation fault measuring method. The electric power communication network includes network units including cables and devices. The method includes the following steps of setting the hazard degree of the fault mode; determining the influence of the network units; determining the operational failure indexes of all network units; and measuring the operation faults of the electric power communication network. The measuring method defines the influence degree of the network units, so that the operational failure indexes contain the influence degree of the fault points on the whole network; The faults are subdivided into a set of failure modes, the hazard degree of the fault modes is defined by means of a risk matrix graph, and the influence degree of the whole network on the fault frequency is reflected; the time coefficients are defined, and the influence of the fault mode time length on the whole network is reflected; the calculation of the operation fault index is good in application prospect based on the statistical data of the communication network faults; and the operation failure index calculation method is simple, and the communication network fault condition can be comprehensively reflected.

Description

technical field [0001] The invention relates to a measuring method, in particular to a measuring method for operating faults of a power communication network. Background technique [0002] Power system communication is an indispensable and important part of the power system. It is the basis for the power grid to realize dispatch automation and management modernization, and is an important technical means to ensure the safety and economical dispatch of the power grid. With the increasing demand of electric power business, the reliable operation of electric power communication network becomes more and more important. A large-scale power communication network faces multiple challenges, and failures have a direct impact on its reliable operation. The power communication network's ability to transmit services under the influence of failures is an important and direct indicator of its own operation quality. [0003] At present, theoretical research on the impact of power communic...

AI Technical Summary

Problems solved by technology

The existing problem is that the operation of the power communication network is mainly to ensure business transmission, and the method indicators of graph theory such as the shortest path are not suitable for the power communication network. Therefore, the method of graph theory has inherent defects in the evaluation of the power communication network

In terms of reliability evaluation, there is currently a lack of systematic and practical reliability analysis and quantitative evaluation methods, and it mainly focuses on reflecting the overall / average level of the network and the services it carries, which cannot fully meet the requirements of communication network system reliability analysis and risk warning
