Research Of Network And Security For Centralized Control Center

With the development of Internet technology, internet technology has already penetrated into all fields. This has made possible the remote monitoring of water electricity. However, the benefits of the new technology have also brought some new problems. From the certain meaning the safety problem of network is the latest and the most outstanding problem among them.The thesis bases itself upon the network construction of Lantsang Cascade Hydropower Plant Supervisory Control system. Analysis of characteristics, objectives, strategies and measures of centralized control center network protection. Then design an evaluation model from the risk of Lantsang Hydro Power Plant Supervisory Control system faced. There are some in common use technique such as backup and restore, firewall and intrusion detection system and so on. Finally gives Lantsang Hydropower Planning centralized control center and design of the overall program.Due to the network's construction can not be achieved by piling up safety product and some technique in brief, so with the concept of the system engineering, according to the fact situation of Lantsang Hydro Power Plant Supervisory Control system, introduce the communication to water and electricity plant base in the lengthways authentication and redundancy. Then the article design the network security rules between the areas and the network security rules inside the area. This kind of network includes many Ethernet in every area. On the safety aspects of the overall plan will not only do a good clear standards, but can do focused, both concise, clear, and also allows the implementation and maintenance more convenient.Finally, sum up the papers for the security and future of the networking prospects Online monitoring network, including health and safety data flow. I believe these studies will be benefit to remote monitoring and control technologies, in particular play a positive role in building the centralized control center.
