Safeguard system for power secondary system

Abstract

A safeguard system for a power secondary system comprises an application security equipment and system, a safety operation and maintenance system, a forward and reverse isolating device and a personal communication gateway, wherein the application security equipment and system is arranged in a production control area, the safety operation and maintenance system is arranged in the production control area, a production management area and a management information area, the forward and reverse isolating device is arranged between the production control area and the production management area, and the personal communication gateway is arranged between the production management area and the management information area. The production control area comprises a service module of a power secondary system real-time or quasi real-time service. The production management area comprises a service module for collecting and managing data in the production control area. The management information area comprises a service module for managing information. The power secondary system is divided again based on the technical feature and the deployment architecture of the power secondary system, the arrangement of safety protection is carried out based on the division of a safety area, the deep protection for the power secondary system is achieved from different aspects, and the safety of the power secondary system is improved.

Description

Technical field [0001] The invention relates to the field of safety protection of electric power systems, in particular to a safety protection system oriented to electric secondary systems. Background technique [0002] The power secondary system refers to the information system for controlling, monitoring and managing the primary power equipment, and generally mainly includes power monitoring system, power dispatching operation management system, power communication and data network, etc. With the construction and development of smart grids, the functions, forms, deployment architectures and implementation technologies of power secondary systems have also undergone significant changes. The main manifestations are: enhanced integration, that is, various business systems are deployed on the bus in the form of services , For service requesters to call; the deployment architecture is loosely coupled to maintain the independence of each business module (or service); the implementatio...

AI Technical Summary

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
