Electric power communication system hidden danger risk assessment method and system

Abstract

The invention provides an electric power communication system hidden danger risk assessment method and system. The method comprises the steps of obtaining parameter data of an electric power communication system; according to the obtained parameter data, carrying out hidden danger assessment. At least four levels of hidden dangers are included: the hidden danger is level-4 when a protection safety control service channel is damaged, the hidden danger is level-3 when a certain channel under the protection safety control service is interrupted but the service is continuous, the hidden danger is level-2 when the protection safety control service is interrupted, and the hidden danger is level-1 when all businesses under the protection safety control business protection group or the primary line are interrupted. According to the invention, the point of the hidden danger risk in the electric power communication network can be quickly determined, and the hidden danger grade and risk grade evaluation accuracy of the hidden danger point are improved.

Description

technical field [0001] The present disclosure relates to the technical field of power communication system evaluation and risk assessment, and in particular to a method and system for risk assessment of hidden dangers in power communication systems. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] The power communication network is another physical network of the power grid company besides the power grid. It is an operating platform that carries various power communication services. The basic transmission network is the foundation of the entire communication network. Although the transmission network has different protection methods at different levels, such as MSP protection at the optical path level, SNCP protection, 2M cut protection, and AB port protection at the channel level, etc., but in the transmission network Among them, when a...

[0003] The power communication network is another physical network of the power grid company besides the power grid. It is an operating platform that carries various power communication services. The basic transmission network is the foundation of the entire communication network. Although the transmission network has different protection methods at different levels, such as MSP protection at the optical path level, SNCP protection, 2M cut protection, and AB port protection at the channel level, etc., but in the transmission network Among them, when a node or two nodes are separated from the entire transmission network due to failure or maintenance, hidden risks will occur at the optical path level or service channel level

[0004] The inventor found that the current common practice in the industry is to consult a large amount of complicated data when designing or transforming transmission networks and business channels, and analyze and compare them to avoid hidden dangers and risk points, and give reasonable suggestions for creation or transformation. Very familiar with the entire transmission equipment network, optical cable network, and service channels, which greatly reduces the work efficiency of dispatchers and restricts the maintenance of the transmission network and service channels by dispatchers
