Research And Application Of Automation Systems For Centralized Control Station

With the State Grid Corporation of "a special four "and" three episodesof the top five" strategic depth forward, Grid approach to development hasundergone profound, To pay UHV DC transmission system is characterizedby modern large power grids has been basically formed. The company’sproduction management intensive, lean, standardization and specializationrequirements, build intensive, efficient operation, the time is ripe forlarge-scale production system.The implementation of the control mode to adapt to the rapiddevelopment of grid level, the real downsizing to improve efficiency, butalso vigorously promote science and technology used in the construction ofpower grids. In this paper, the development status of the existing centralcontrol Substation research. By comparison with the conventional substation,analysis of the technical characteristics and content of the control centerstation automation system, Summarize the advantages and disadvantages ofthe control model, analyze problems and improve the solutions, vigorously promoting the "three episodes of the top five for the State Grid Corporation,to provide experience to carry out large-scale promotion and application oflarge-scale production during the big run mode control mode.This paper focuses on the central station automation system controlmode network structure, from the station level, bay level hierarchicaldistribution of introduced substation upper scheduling data networktechnology, and research and analysis; Detailed analysis of the statutetelecontrol protocol and questions and answers, remote central station by theuse of cyclic; characteristics of the central station, the design and toestablish a rational database analysis of the data acquisition module;Substation security system strategy, technology research and design of asecondary security program.In The end, the actual engineering, in-depth understanding and analysisof the design of automation systems in the control mode to achieve, and theproblem still exist today and the direction of development.
