Research On Development Modes And Strategies About Distribution Automation In Lu'an District

As an important means to improve the reliability and quality of power supply and improve the management level of distribution network,distribution automation has been paid more and more attention.In order to respond positively to the development plan of power distribution automation construction and to solve the problem of weak network structure,low automation level and low power supply reliability of distribution network in Lu'an area,the thesis relies on the technical standards of the state grid and the construction experience of the pilot units in Anhui province,in close connection with the actual situation of the district to carry out distribution automation construction strategy and program research.First of all,in order to fully grasp the development status of distribution network in Lu'an area,the thesis makes a detailed investigation on the current situation of distribution network in Lu'an area,mainly including the d ivision of power supply area,the configuration of grid structure,the automation degree of distribution equipment,distributed power supply and multiple The number of load access,the distribution of communication information system and the application of distribution management system.Then,based on the current situation research,the thesis discusses the problems existing in the construction of distribution automation in Lu'an area,combined with the distribution network of Anhui power grid,the thesis puts forward the goal of realizing the full coverage of distribution automation in Lu'an area by the construction of different stages and different regions.Based on the construction goal of the construction,from the aspects of distribution main station,fault processing mode selection,distribution equipment reformation,distribution terminal equipment configuration,communication system construction and information security construction,analyzes the construction principle of different power supply area,and gives the corresponding con struction strategies and programs;Finally,the thesis makes a comprehensive evaluation of the effectiveness of distribution automation in Lu'an from three aspects: technical benefit,economic benefit and social benefit.The thesis has some guiding significance for the construction of the distribution automation system in this area,and can also provide some reference and reference for the construction of distribution automation in similar areas.
