Problems solved by technology

The health evaluation method based solely on AHP can directly score each index through the information system health index scoring rules formulated by expert experience, but it relies too much on a single expert experience, and the reliability of expert experience directly affects the final performance of the entire system. Health Score Results

Embodiment 1

[0081] Such as figure 1 As shown, a method for evaluating the health of a power information system in this embodiment includes the following steps:

[0082] Step 1: Select the indicators required for power information system health assessment, clarify the meaning of each indicator, and standardize them. In this embodiment, based on the evaluation requirements of the power grid information system software and hardware, combined with the characteristics of the power cloud platform, and aiming at the effectiveness, efficiency, and security requirements of the information system, the following basic indicators of the evaluation model are selected:

[0083] Functional health: Functional health reflects the degree of realization and availability of information system functions. The corresponding monitoring data is the effectiveness of each function, and the effectiveness of a certain function a i , using two indicators of function realization degree C and failure rate F to evaluate...

Embodiment 2

[0122] Based on the same inventive idea, the present invention also discloses a system for assessing the health of an electric power information system. The implementation of each device in the system is similar to the principle of the method for evaluating the health of an electric power information system, and the repetition will not be repeated.

[0123] The power information system health evaluation system described in the embodiment of the present invention includes:

[0124] A monitoring data acquisition module, configured to acquire monitoring data of the power information system to be evaluated for health;

[0125] A monitoring data specification module, used to standardize the acquired monitoring data;

[0126] The evaluation index quantification module is used to obtain the corresponding evaluation index quantification value according to the standardized monitoring data;

[0127] A health evaluation model module, used to calculate the health value of the power infor...

Abstract

The invention discloses an electric power information system health degree assessment method and an assessment system thereof, and the method comprises the following steps: 1, selecting an electric power information system health degree assessment index, each assessment index comprising a plurality of monitoring data, and normalizing the assessment indexes; 2, according to the health degree assessment index, constructing a power information system health degree assessment model with a hierarchical structure, the health degree assessment model comprising a plurality of health models, and each health model requiring a plurality of health degree assessment indexes; 3, scoring the health degree assessment model layer by layer from bottom to top by combining a Delphi method and an analytic hierarchy process, and constructing a judgment comparison matrix; and 4, according to the actual monitoring data, calculating a health degree assessment value from bottom to top to obtain the health degree of the whole information system.

Description

technical field [0001] The invention relates to the field of electric power information systems, in particular to a method for evaluating the health of an electric power information system and an evaluation system thereof. Background technique [0002] At present, the informatization of the power industry is developing towards cloud computing in an all-round way. The information system based on the cloud environment is continuously applied, which plays a comprehensive supporting role in power grid security, operational efficiency, customer service, and new business development. At the same time, with the continuous improvement of the power system business work support capability and the substantial integration of the main business, the scale of the information system has also expanded rapidly. However, due to the complexity of the system and cloud environment, the reliability, security, and stability of information systems have become increasingly prominent. Therefore, in o...
