Problems solved by technology

The traditional power communication network equipment risk analysis model mainly involves the technical factors of the equipment itself, and does not take into account natural factors such as rainstorms, typhoons and social factors such as "power guarantee period"

Embodiment

[0312] The risk parameter setting of PCM equipment is shown in Table 9. Through the PCM risk quantitative assessment method, it is calculated that the baseline risk of PCM equipment is 4.55, and the risk based on the problem is 16.38. It means that the risk value of the PCM equipment falls within the normal range, indicating that the risk level of the PCM equipment is relatively low, and normal maintenance is enough.

[0316]

[0317] By improving the risk value observation of certain risk factors, see Table 10, by improving the key indicators of equipment performance and the risk value of the operating state, according to the proposed risk model, it can be calculated that the baseline risk value of PCM equipment in this state is 38.15, The issue-based risk is 137.34. It can be seen that the baseline risk of PCM equipment is within the high-level risk range. Therefore, detailed assessment and inspection should be performed on the eq...

Abstract

The invention provides a security risk quantitative evaluation method of PCM equipment in power communication. Technical characteristics of communication equipment and different characteristics of risk evaluation under the special natural and social environments are fully considered, and the provided risk evaluation optimizing method can guide security risk quantitative evaluation of power communication network transmission equipment, exchange equipment and other equipment in a similar way. The board card redundancy, the operation condition, the environment factor and the management factor of the power communication equipment are taken into consideration of security basis risk of the power communication PCM equipment, and the importance degree and social factors of the bearer service of the power communication equipment are taken into consideration of the provided risk with the problem. The guidance effect can be achieved in analysis of equipment risk of the power communication network.

Description

technical field [0001] The invention relates to a risk assessment method, in particular to a security risk quantitative assessment method of PCM equipment in electric power communication. Background technique [0002] The power communication network carries a large number of related businesses of power production, control and marketing, and is an important part of the power information communication system. A large number of power services need to be transmitted through the power communication network, including telecontrol data, relay protection signals, administrative telephone signals, video, video and teleconferencing signals, etc. The power system is increasingly dependent on power communication. The influence of network time, risk and failure on the power system is also becoming more and more serious. Improving the reliability of the power communication network and reducing the occurrence of risk events cannot only rely on the design and optimization of the network str...
