Problems solved by technology

[0004] At present, there is no relevant literature on the definition and evaluation of the resilience of the power monitoring system, and it is still in its infancy. How to establish a complete set of resilience evaluation theory and dynamic evaluation indicators of the power monitoring system is the theoretical basis for the system to respond to emergencies, and it is also an important way to improve the resilience of the power monitoring system. Technical guidance on the resilience of the system in the face of internal and external information disturbances

Embodiment 1

[0042] Such as figure 1 As shown, the present invention is based on the entropy value method power monitoring system toughness assessment method comprising the following steps:

[0043] Step 1: Analyze the resilience characteristics of the power monitoring system from two different dimensions of time and space.

[0044] Time Dimension Features

[0045] For the analysis of the resilience of the power monitoring system, in terms of time dimension, it is divided into before the security incident, when the security incident occurs and after the security incident occurs, as follows: figure 2 shown. Before a security incident occurs, system resilience is mainly reflected in the fact that it relies on its own physical isolation, security partitions of different systems, and regular integrity checks to complete relevant preparations before a security incident occurs; when a security incident occurs, the system relies on Its own prepared response plan flexibly reduces the impact of...

Embodiment 2

[0077] In Embodiment 2, four indicators of physical toughness, network toughness, host toughness, and application software toughness of the power monitoring system are set up. Based on the above four categories of indicators, the entropy method is used to evaluate the toughness of the monitoring system, that is, there are 16 indicators in total. A small category of indicators (three-level indicators). All the other are the same as embodiment one.

Abstract

The invention relates to an entropy-based method for evaluating the toughness of a power monitoring system, comprising step 1: analyzing the toughness characteristics of the power monitoring system from two different dimensions of time and space; step 2: selecting a plurality of toughness based on the toughness characteristics According to the hierarchical structure of the multi-objective decision-making method, the resilience evaluation index system for the power monitoring system is established; step 3: use the entropy value method to complete the quantitative calculation of the index weight, and obtain the weight value of each resilience evaluation index, and according to the obtained The magnitude of the above weights is used to determine the impact of each resilience evaluation index on the system resilience assessment; Step 4: Calculate the resilience comprehensive score of the power monitoring system as the resilience quantitative evaluation result of the power monitoring system. The invention can realize the effective evaluation of the toughness of the electric power monitoring system, and guarantee the scientificity and accuracy of the evaluation.

Description

technical field [0001] The invention relates to an entropy method-based resilience evaluation method of a power monitoring system. Background technique [0002] The power monitoring system is the neural network and control center of the entire urban power system, and it is also the basis for ensuring the safe and stable operation of the urban power system and power reliability. Although the security protection technology of the existing power monitoring system guarantees the safe and stable operation of the power system, with the development of information technology and the continuous evolution of information security policies in various countries, the trend of nationalization of network attacks is obvious. Attack has become an important form of political and economic struggle. Moreover, the persistence, concealment, and destructiveness of information security attacks have been significantly enhanced, which has greatly increased the difficulty of information security prote...
