Design And Application Of Smart Substation

The Smart Grid is regarded as the solution in security, intelligence, environmental protectionand other aspects of the problem is the most effective power system at present, at the same timeintelligent substation is the core link and basic elements of building a strong Smart Grid.The Smart Grid is a unified and openness as the basic. This paper first analyzes the advantagesand disadvantages of traditional substation and traditional substation and substation intelligentanalogy analysis, the composition and function of structure based on a huge difference between thetwo, and then put forward based on the primary, the construction method of intelligent substationsecondary equipment, but also the technical characteristics of the structure of the substation theanalyses and expounds its significance for the future power grid. In this paper, to maintain theexisting basic structure does not change at the same time, the existing substation design a unifiedplatform structure can collect basic information digitization based on this structure, the informationstandard protocol, network management system more stable, more unified, time synchronization,and finally by a level contact finish development the grid information system task. Measurementand control device of intelligent in the design in this paper is based on the measurement and controlit is realized according to the synchronous clock technique. The principle of completesynchronization acquisition time synchronization digital signal data in multi clock device based onthe unified model, and used to complete the standardization of information and timingsynchronization, and finally unified unified grid levels from the root to the equipment standard rules,the basic information standard.
