Research And Application On Distribution Net-work Automation System

Along with the rapid development of national economy and the people's standard of living rise ceaselessly, the users to power the reliance of the more and more high, followed by the power supply reliability of power grids demand more and more. Our distribution network automation still in the experimental stage, most parts of the pilot project mainly feeder automation is given priority to, the function is relatively single; In system integration, each single automation self-contained, lack of comprehensive consideration; In the application level, still in the primary stage of development. Especially for developed economic regions, and how to take the most suitable way, in engineering realization of distribution network automation of pilot modification and running, how to promote distribution network planning, it is widely realized the automation of this paper main research topic.In order to solve the enterprise is weak, vulnerable to power grids accident and emergency fault interference, influence power supply reliability problems. Based on the distribution network automation system to study as the background, the main characteristics of combining enterprise grid of distribution network automation system planning, equipment selection, pilot project implementation, system function testing of the deep discussion and research, especially for distribution network automation of fault engineering realization of regional gap technology are studied.Papers on my participation in the ring net line distribution automation system in line fault cases network once refactoring engineering realization of distribution network automation system, complete run-in test methods were introduced, and summarized the conclusion.In order to understand current model of distribution network automation equipment and the voltage type distribution network automation equipment characteristics, this paper also detailed research and introduces the current model and the voltage type two kinds of distribution network automation equipment respective characteristics. The practical application in engineering, Humen pilot distribution network automation system according to the different characteristics of two kinds of equipment, in the system are applied, two kinds of equipment technology-innovation, after a period of operation practice achieved very good results.According to the operation practice of conclusions and enterprise the characteristics of distribution network, this paper puts forward enterprise distribution network of distribution network pilot automation system of the problems and future distribution network automation of improving direction.
