Safety protection system for power secondary system

Abstract

A safety protection system for power secondary systems, including: application safety equipment and systems deployed in the production control area, and a safety operation and maintenance system deployed in the production control area, production management area, and management information area, set in the production control area The positive and negative isolation device between the production management area and the production management area, and the dedicated communication gateway between the production management area and the management information area; the production control area includes the business modules of real-time or quasi-real-time business of the power secondary system The area includes business modules for collecting and managing data in the production control area, and the management information area includes business modules for information management. Based on the technical characteristics and deployment framework of the power secondary system, the present invention re-partitions the power secondary system, deploys security protection based on the division of this safety zone, and realizes the in-depth protection of the power secondary system through different levels , improving the security of the power secondary system.

Description

technical field [0001] The invention relates to the field of safety protection of power systems, in particular to a safety protection system oriented to a power secondary system. Background technique [0002] Power secondary system refers to the information system that controls, monitors and manages primary power equipment, generally including power monitoring system, power dispatching operation management system, power communication and data network and so on. With the construction and development of the smart grid, the function, form, deployment architecture and implementation technology of the power secondary system have also undergone significant changes, mainly as follows: the degree of integration is strengthened, that is, each business system is deployed on the bus in the form of services , for the service requester to call; the deployment architecture is loosely coupled to maintain the independence of each business module (or service); the implementation technology o...

Problems solved by technology

To achieve a specific operation, such as remote access, command delivery, etc., all you need to do is call the corresponding service. The loose coupling between the various modules makes it highly flexible, but there are also obvious hidden dangers to information security. , the current security protection technology architecture of the power secondary system does not consider the information security issues brought about by the loose coupling of module services
