Problems solved by technology

[0004] Disadvantages of using principal component analysis: using principal component analysis method is easy to screen out some simple but large contribution factors, which cannot truly fully reflect the risk of power communication network, and the reliability of power communication network is not high; increase the number of samples However, at the same time, it also increases the amount of calculations for the evaluation of the power communication network, which is not conducive to the operator's simple, clear and convenient grasp of the method, which increases the workload and reduces work efficiency.

Embodiment Construction

[0027] For ease of understanding, the following will be described in conjunction with the accompanying drawings.

[0028] See figure 1 , the present invention proposes a method for risk assessment of a power communication network, comprising steps:

[0029] 101. Conduct hierarchical analysis on risk factors;

[0030] Various risk factors are analyzed hierarchically, and risk factors with the same attributes are regarded as elements of the same set of risk factors.

[0031] 102. Obtain the quantitative value of the degree of impact of risk factors on risks;

[0032] Obtaining the quantitative value of the degree of influence on risk between two sets of risk factors is to obtain the quantitative value of the degree of influence of one risk factor set on risk and the degree of influence of another risk factor set on risk.

[0033] 103. Calculate the risk factor weight coefficient according to the quantified value;

[0034] Calculate the weight coefficient between the two risk...

Abstract

The invention provides a method for assessing risk of an electric power communication network. The method comprises the following steps: hierarchically analyzing various risk factors, and using risk factors with the same attribute as elements of the same risk factor set; acquiring a quantized value of degree of influence on risk between two risk factor sets; calculating a weight coefficient between the two risk factor sets according to the qualified value; calculating a risk value according to the weight coefficient; and adjusting the corresponding risk factor in the electric power communication network according to the risk value. The invention further provides a device for assessing risk of the electric power communication network. Due to the method and the device for estimating risk of the electric power communication network, the comprehensiveness of risk assessment of the electric power communication network is improved, the reliability of the electric power communication network is enhanced, and the work efficiency is simultaneously improved.

Description

technical field [0001] The invention relates to the field of power communication network safety monitoring, in particular to a method and device for risk assessment of a power communication network. Background technique [0002] With the development of the power communication network, a large number of power system services need to be transmitted through the power communication network, including a large number of services such as telecontrol data, relay protection signals, administrative telephone signals, video, video, and teleconferencing signals. The dependence on communication is increasing day by day, and the impact of time, risk and failure of the power communication network 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 network structure in the design stage of the communication network. Design and optimization, but need to evalu...
