| Distribution network is an important part of the power grid,with many lines and complex systems.At present,there are deficiencies in China's distribution network such as unreasonable network structure,poor overall contact capacity,and low degree of automation.Distribution network automation can not only make the entire power grid system stable and safe power supply,but also effectively avoid blackouts.In order to implement the central government s development strategy for revitalizing the northeast old industrial base and realize the power grid development plan during the 13 th Five-Year Plan period in Liaoning,the Shenyang Power Supply Company of the State Grid based on the "13th Five-Year Plan" Distribution Automation Implementation Opinions formulated by the State Grid Corporation of China The intelligent distributed power distribution automation demonstration project was carried out.The project relied on Jianping intelligent distributed power distribution automation demonstration project to conduct in-depth research on the issues related to the automation of power distribution network reconstruction in Jianping area.The distribution network automation technology is analyzed,and the main principles,characteristics of the application of automation technology for distribution network,the specific functions of the distribution network automation technology,and the constituent elements of the distribution network automation system are summarized and analyzed.Research shows that distribution network automation technology can effectively ensure the safety,stability,efficiency,and low energy consumption of the entire power system,and is conducive to promoting the overall economic development in the Jianping area,and plays a facilitating role for the convenience of people's lives.The status quo of distribution network in Jianping area was studied,and the main problems of primary grids and distribution equipment in distribution network in Jianping area were analyzed.The research shows that at present,the distribution network in Jianping area can not meet the demand of electricity load,the overall liaison ability is poor,and the grid structure is irrational,which is not conducive to the long-term development of the Jianping power grid.Based on this,the automation planning goals of the Jianping distribution network are proposed.Improve the level of power grid automation.The first grid structure of Jianping distribution network was optimized and transformed,and the distribution automation automation master system,feeder automation system,distribution module and terminal system,and distribution communication network of the entire grid in Jianping area were completed.After the transformation,the standardization,stability,versatility,safety,and reliability of the entire Jianping network have been improved.The power supply reliability of the Jianping distribution network is expected to increase from the original 99.83% to 99.94%. |
