The Research On Information Security Management Of Intelligent Power Substarion

The construction of intelligent power substation is a key measure of power grid development which meets the development requirements of "Accelerate the construction of Resource-saving and Environment-friendly Society" in the "National12th Five-Year Plan". First, the area the intelligent substation occupied is smaller, equipment commissioning cycle is shorter and the maintenance cost is lower; Second, the digital smart substation can be adjusted to real time grid operation mode which effectively reduce the power loss with the features of economic and environmental protection; Third, the intelligent substation can achieve the goal of automated operation and real-time monitor which improves the operation management level. The construction of intelligent power substation is becoming an inevitable requirement of grid revolutionary. With the transformation from substation to the intelligent power substation, primary equipments will be upgraded to a smart electrical equipment, secondary equipments will be intelligent control unit, which requires network equipments to match the new technical specifications. Intelligent substations enhance the economic and social benefits. Due to the feature of digital, information technology and network characteristics, it faces information security proble. Therefore, the study of smart grid information security management is crucial.As an important part of smart grid construction, the intelligent substation is the most important collection point of operating parameters and control point of execution of power grid, so the information security management issues should not be paid more attention. This paper introduces the concept and architecture of intelligent substation, and analyzes the characters of information systems which face the risk of information security.According to the international standard of information security management system research, this paper studies the construction of the intelligent substation information security management system and the design of intelligent substation tube control process. In the first part, this paper mainly introduces the basic principles of security responsibilities, management measures and technical measures four parts; In the later part, this paper mainly talks about the seven-cycle stage of initial requirements, design, development, on-line, operation and maintenance and the abolition. In order to test the information security management system, this paper designs the evaluation indicators of intelligent substation of information security management system.
