Electric power information system health assessment method and system based on fuzzy reasoning theory

Abstract

The invention discloses an electric power information system health assessment method and system based on fuzzy reasoning. The method comprises the steps: collecting logs generated in an operation process of an electric power information system, and carrying out preprocessing on the log data; carrying out log information screening and multi-source log fusion by adopting a fuzzy reasoning theory, and analyzing and processing log information generated by different heterogeneous devices; collecting vulnerability log information and operation log information of the electric power information system, and carrying out importance evaluation to acquire a high-risk security event; converting structured log data and unstructured log data based on a log event mining technology; and by constructing ahierarchical structure, determining the membership relationship of element arrows of a hierarchical layer, carrying out consistency check on single criterion sorting of each layer, formulating a system health assessment index value, and carrying out health assessment of the electric power information system.

Description

technical field [0001] The invention relates to the technical field of electric power system management, in particular to a method and system for evaluating the health of electric power information systems based on fuzzy reasoning theory. Background technique [0002] In recent years, with the continuous deepening of the information construction of the State Grid Corporation of China, each major major has basically realized online office operations supported by the information system through the construction and improvement of its own professional system, which has greatly improved the efficiency of production management. Industry information The number of systems being built is increasing, and at the same time, the requirements for system operation security are also getting higher and higher, which poses a huge challenge to the operation, maintenance and management of information systems. However, the operation, maintenance and management of internal information systems in p...

[0002] In recent years, with the continuous deepening of the information construction of the State Grid Corporation of China, each major major has basically realized online office operations supported by the information system through the construction and improvement of its own professional system, which has greatly improved the efficiency of production management. Industry information The number of systems being built is increasing, and at the same time, the requirements for system operation security are also getting higher and higher, which poses a huge challenge to the operation, maintenance and management of information systems. However, the operation, maintenance and management of internal information systems in power companies However, it lacks a suitable system for support, and there is an embarrassing situation of insufficient support for the informatization level of the information profession

[0003] For the management of information system development, maintenance manufacturers, and operation and maintenance manufacturers for power enterprise services, the operation and maintenance management of power information systems still needs to divide resources for processing, thus greatly increasing the load on power information systems. Power information systems are the core of the power industry , it is very necessary to supervise its healthy operation. The operation status of the existing power information system requires corresponding supervision by operation and maintenance personnel, increasing manual pressure, and the supervision process is subject to manual restrictions, low statistical efficiency, and prone to erroneous evaluation
