Research on Key Technologis of Power SystemInformation Security Model

With the popularity of information technology and network technology in power system, the business system of power industry is developing in the direction of openness, interconnection and standardization, and the safe operation of power system have gradually formed the dependence on the security of information system The security threats to the power system, and the potential for insecurity. Based on the analysis of the current classic model of the existing information security, security system model should aim for the security requirements of power information system, regard protecting entity security as the core, take the legal and human factors as the guarantee, take the system safety engineering process as a support, and strengthen the safety awareness of all personnel through safety education and training. The model is a dynamic, circulation, and constantly perfected process. The reliability of the current power grid and the future energy system architecture design has an important guiding significance.
