Analysis Of Network Security Protection System In District Power Dispatching

The focus of secondary power system in power dispatching automation is to ensure the real time monitoring system security and dispatching data network security,to resist various forms of vandalism and attacks by hackers,viruses,and malicious codes,especially to resist group attack.It is to prevent primary system accidents or large area blackout,as well as secondary system collapse or paralysis.With the enlargement of power grid scale and the rapid development of smart grid,secondary power security system protection plays a more and more important role in dispatching automation.Under the background of dual plane dispatching data network construction and smart grid construction in the national grid,it first introduced the development process of the secondary security protection system in electric power dispatching and the status quo.of power dispatching secondary security system of Hangzhou power supply company.It analyzed the demand on the secondary system security of power dispatching automation of the double plane dispatching data network and th e development of smart grid.The deficiencies of existing secondary system was also analyzed.It also made plan for the future secondary system security architecture.Then it analyzed the application of some key technologies like the firewall,access control,anti virus in the secondary security system of power dispatching station.It also briefly introduced the principle and function of them.Finally,on the basis of the planning and analysis of the key technology of secondary security,it proposed rectification scheme and implementation procedures of power dispatching automation of Hangzhou power supply company,and formulated the longitudinal encryption device tunnel and policy configuration specification.At last,the future development scheduling of the secondary system security in Hangzhou power supply company were analyzed.
