Design And Realization Of The Distribution Automation In Core Area Of Dalian

Distribution automation system is to distribution a grid and distribution network topology connection and distribution equipment as the physical basis, with modern communication, computer and power electronics technology, distribution network terminal equipment and distribution lines for real-time monitoring, control and rapid response and fault treatment of integrated platform system. Distribution network automation system provides a safe, reliable and high quality power supply to the power users, and it is also an important part of the construction of smart grid in China.First the distribution automation system structure, function and development process were briefly introduced, and combined with the Dalian area of 10kV distribution network of, in-depth analysis of the core area of existing distribution network and operating equipment, in the face of the distribution network are part of the grid structure is unreasonable, equipment operation risks, distribution network automation without coverage and comprehensive management and low efficiency, and draws a conclusion that in the core area of distribution network has been unable to meet the electricity demand in the region gradually increase.According to the requirements of the overall development of distribution network planning, present scheme of reconstruction of the core area of distribution network, including distribution network transformation and terminal equipment transformation plan; combined with the specific requirements of distribution network of the core area, further elaborated the construction scheme of distribution automation system, including the master station of the system each function module, the master station and the terminal station of the system construction at the same time, the system carried out a detailed analysis and comparison, the construction scheme of the communication system of optical fiber communication and power line carrier communication combination; finally analyzes the benefit and the social benefit management of distribution automation system, economic benefits, and the economic benefits of a quantitative comparison, proved the theoretical significance of the system construction the actual value, and provides a theoretical basis for the comprehensive coverage of the distribution network automation in Dalian area valuable experience.
