| In recent years, the urban regional power grid exposes many problems. If the power companies still use the traditional equipment and management methods, which will be difficult to achieve effective management and cannot meet the economic development and people’s demand for electricity. Only starting from the power grid construction,stribution network automation improving the network structure and the level of automation,can basically meet the needs of customers.Developing ningbo distribution automation pilot and research is very meaning of.The goal of this project is to build integrated distribution automation systems, through the implementation of distribution automation pilot project, the completion of full coverage automation and communication networks in Ningbo area, to further improve the distribution network, in achieving a comprehensive distribution network topology function distribution automation system based on the realization and distribution SCADA and feeder automation, to achieve integration with network integration and sharing of information and expansion of distributed power, micro-grid and energy storage devices and other devices access function, the initial realization of power distribution network intelligent self-healing, visualization and user interaction with the scheduled operation and other functions. Preliminary achieve integration of intelligent power distribution regulatory requirements, building into a information technology, automation, interactive features of the smart distribution grid.Based on the background, significance and current situation of the development of distribution automation exposition, Detailed planning of Ningbo Haishu distribution automation is done, including:By managing and analyzing data of power, distribution network and the main station system of Haishu district in medium voltage, find out the weak links and the existing problems of medium voltage distribution system and provide evidence for the distribution network planning and reconstruction.According to the actual situation of distribution network in Haishu district, carry out a pilot study of distribution automation planning, discussing the overall planning objectives, implementation plan and design of the main station and sub-station to provide guidance and reference for design of distribution automation planning in the future.Discuss the communication scheme in distribution automation according to the principle of the proposed scheme construction and transformation. |
