Embodiment Construction

[0058] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0059] The embodiment of this application proposes a smart substation layered health index evaluation method. The smart substation includes multiple layers, and each layer includes multiple devices. The evaluation and presentation of the three different levels of the site makes the calculation of the health index of the whole site more comprehensive and accurate; the basic health index of the device is corrected by using the device correlation, which fully considers the network security risks caused by the device correlation The impact of diffusion on system security ensur...

Abstract

The invention relates to a hierarchical health degree index assessment method for an intelligent substation. The method comprises the following steps: obtaining a basic health degree index of equipment according to static information and dynamic information of the equipment; obtaining device relevance according to the communication connection relation between the device and other devices, correcting the basic health degree index of the device according to the device relevance, and obtaining the health degree index of the device; according to the health degree index of the equipment in one layer and the importance weight of the equipment, obtaining a hierarchical health degree index of the layer; and according to the hierarchy health degree index of each hierarchy and the equipment importance weight sum of each hierarchy, obtaining the whole-station health degree index of the intelligent substation. By adopting the method, the accuracy of total-station health degree index calculation can be improved. The invention further relates to a hierarchical health degree index assessment device for an intelligent substation, computer equipment and a computer readable storage medium.

Description

technical field [0001] The present application relates to the field of electrical technology, in particular to a method and device for evaluating a hierarchical health index of a smart substation. Background technique [0002] With the continuous improvement of the automation and intelligence level of the substation control system, the scale and complexity of the system software and hardware are increasing rapidly, and the risks and challenges faced by its safe and stable operation are increasing day by day. [0003] As a key infrastructure related to the national economy and people's livelihood, the power system has always been the primary target of hacker attacks, which has sounded the alarm for the network security work of the power system. As an important component of the power system, smart substations need to be improved and perfected urgently for their network security assessment and protection methods. [0004] However, existing smart substations only conduct inform...
