Research On Security Protection Technology Of Wind Farm Power Monitoring System

With the gradual implementation of the national "network power" strategy,more and more attention has been paid to the construction of network security in the power industry,and it is urgent to build a network security protection system in line with the characteristics of the power industry.As a new energy power generation enterprise,wind farm undertakes the important task of providing clean energy for the country and society.As the terminal node of power system,the effectiveness of power network security of its monitoring system is very important for the safe operation of power grid,which is generally composed of many network-based sub control systems.Therefore,there are higher requirements for the network security protection of the wind farm monitoring system.Therefore,according to the relevant provisions of the State Grid,the security protection of the power monitoring system is carried out in order to prevent all kinds of risks leading to a system or a greater security accident.Firstly,this paper analyzes the risk of the power monitoring system and briefly introduces the technical measures needed,compares the defects of the power monitoring system,makes the overall security protection plan,determines the internal division area according to the business importance of the wind farm,gives the detailed implementation plan,and introduces in detail all kinds of security equipment and network equipment needed by the system,deployment mode of host equipment,equipment type and detailed design scheme.Secondly,this paper proposes a set of distributed network information security protection system.Compared with the traditional power monitoring system security protection,the distributed security protection system is used to collect the log and alarm information generated by common security equipment,network equipment and host equipment when they are running,and send out the alarm,notify the management personnel to deal with them,and carry out real-time monitoring and communication on these equipment Through the visual interface to mine and analyze the stored historical data again,produce detailed statistical information,provide more accurate data to managers,and inform managers to improve the level of safety protection.The content of this study has been applied in a safety protection project of new energy Dabancheng wind power plant.The businessbetween each safety zone is economic and safe.
