| Distribution network automation is the inevitable result of the development of power market and economic construction. With the development of power market in Bazhou, the weak links of the distribution network is more and more outstanding, leading to the inharmonious situation between power demand and power facilities. Along with the transition of market concept and the needs of the power development, the distribution network integrated automation has become a very urgent task for power supply enterprises. Therefore, in this paper, the construction plan of Bazhou distribution network automation system has carried on the detailed analysis and research.First of all, we do analysis to the present situation of the grid, the distribution network equipment, the distribution network automation application status, the present status of distribution network communication system in Bazhou, draw the problems of power distribution network in the application of distribution network automation, which laid a foundation to this paper. Second, respectively from the master station, terminal and communication channel, three parts of the overall structure of the distribution network automation system are analyzed; And the security monitoring, control and protection function of the distribution network automation system are analyzed. Again, the main construction and retrofit scheme of the distribution network automation system was studied, including the construction and transformation target of master station, configuration scheme of the main functions, hardware and software and the information interaction of master station and other systems. Then, the configuration scheme of power distribution terminal(DTU) and feeder terminal(FTU) and wireless private network communication construction and retrofit scheme was studied. Finally, the investment and economic benefit of distribution network automation system are analyzed. |
