Optimization of Design Scheme for Urban Distribution Automation System

In order to guide the construction of urban distribution network automation system effectively, the primary mode, intermediate mode, and advanced mode of urban distribution network automation system practical schemes was put forward based on meeting the system design requirements of openness, compatibility, expansibility and reliability. The requirements of power network architecture and equipment for distribution network automation system were analyzed, the functions and configuration requirements of distribution automation master station, distribution automation slave station, and distribution automation terminal for distribution network automation system were summarized, the information interaction and information sharing mechanism of distribution automation system were described. Function composition and structure form of automation system for the three kinds of practical urban power distribution network were analyzed detailedly, the optimal design scheme based on grey relation projection theory was achieved, and those provide a scientific decision-making basis for the improvement and construction of urban distribution network automation system.
