| Nowadays, China’s industrialization and the depth of integration of information technology and the rapid development of the Internet, as the transfer and exchange of information media has become a very important basic element in the operation of the whole social life. In today’s information-rich age, we reform and technological innovation at the same time, more attention to the safety information. Electricity is one of the basic industries, which provide support for the country’s economic development in the protection of people’s daily life, but the entire power system from the organization can be divided into generation, scheduling two systems and power generation, transmission, distribution, consumption of four links. In recent years, with the rapid development of various information and communication technologies and their use in large-scale power systems, security and stability of operation of the power system has brought a threat, accordingly, need for electric power information network security issues in-depth analysis and research. Based on the power of information on the safety analysis, clear the current power information network security threats mainly from the Power Information Network threats and border security threats power information system, while the evaluation model applied to Power Information Network the goal is to establish reliable information security system for the power plant, reducing internal and external security attacks and threats faced by the plant information system. Network environment has some special power plant, according to the SERC security partitions, network-specific, horizontal segregation, vertical certified ideas, the electricity network is divided into zones I, II district, III district and four districts, and the production control area management information area isolation. Network into logical isolation is generally applied by a combination of physical separation to protect against threats from the Internet, intranet access vulnerabilities. As the need for power plant development of digital, electric power dispatching business systems and data network security, reliability and timeliness presents new challenges, even if the power plant under the internal network isolation, often in actual production management, manage large area Information systems need to talk to other production monitoring system for data sharing between the isolated network to communicate, collect and exchange information necessary for production data. At this point, we need to make in ensuring the safety of the secondary system to meet the conditions for access to the mirror data security based scheduling system designed to meet the growing need for digital management of power plants, to provide real-time and accurate decision-making data for leadership.This paper will focus on how the physical plant quarantine network, to ensure production safety, network security, in data security, transmission security premise of how reasonable and effective to build a power plant in terms of business application system is simple, and real-time, accurate data access scheduling mirror system in a complex network environment.This topic from three directions Mirror web systems, database mirroring, file systems integrated design, will feature real-time scheduling and dispatch management system, data, power load, production targets and other decision-makers need to function through the use of JAV database technology Mirror technology, network protocol programming, encryption technology to design a security solution. Meanwhile, across the isolated network design is based on data exchange must also meet to consider issues related to the security of data exchange, reusability, scalability and so on the whole, this mirror design scheme has been applied in actual power plant project, information into multiple plant upgrade project. |
