Research And Implementation On Electric Power Dispatch Automation Network Security Protection System

With the substantial increase in the development of computer technology andsmart grid dispatching automation level, the power dispatching automation systemnetwork security actracts more and more attention. It involves all aspects of regionalscheduling system, each region has different risks, threats and solutions, and thecontest between threats and security is dynamic no termination.From the current situation, to start dispatching automation system, the potentialsecurity threats and the basic principles of protection of power dispatchingautomation system are analyzed, and then based on new technologies, standardspower dispatching automation system, network level theory and secondary powersystem security requirements, from two angles station master and plant, a newscheduling automation system security program CSSDA is designed in order toestablish full security dispatch automation system security architecture. From ahardware perspective to design power dispatching automation system networksecurity solutions, the hardware architecture design protection programs is presentedand security products in the design and implementation of protection programs areindroduced to ensure that the hardware design boundaries is clear and no blind zoneby focuses on the two firewalls and security isolation device, two important safetyprotection products, in power dispatching automation security system design andimplementation. Then the software of power dispatching automation system securitysystem is degin in Windows, Aix and Linux operating system, and the Oracle andSQL Server database security systems configuration is given. Finally, the mainfunction of power dispatching automation system security system is implemmented.The system works well by operating in a substation in Cangzhou.
