[Abstract]:The distribution system is directly oriented to the users. It is the key link to ensure the power supply reliability and power quality of the users, to improve the efficiency and innovation of the power grid. With the increasing requirements of the power users on the power quality and the power reliability, the more and more high requirements for the distribution network management are put forward, and the distribution automation is implemented. It has become an important link in the construction of distribution network. This paper studies the implementation scheme of intelligent distribution automation in the context of the development of smart grid. The main work is as follows:
(1) the basic architecture of distribution automation, which consists of main stations of distribution automation, electronic station and distribution terminal, is given. The key technologies of distribution automation are analyzed from the aspects of fault handling, loop estimation, power flow calculation, load forecasting, simulation, and the corresponding intelligent application functions.
(2) the basic needs of the construction of distribution automation system are analyzed in depth, and the foundation for the implementation of the distribution automation scheme is laid. The planning target of distribution automation is formulated, and the detailed distribution of power distribution is set up from 4 aspects: the construction of the network frame, the construction of the main station of the distribution automation, the electronic station, the terminal construction and the construction of the communication system. Automatic planning target system, and then follow the planning objectives, from 4 aspects of the implementation of the implementation of distribution automation scheme, and the rapid self-healing, information system integration, interactive construction of the construction of intelligent power grid and other new characteristics of the construction of the scheme.
(3) the distribution automation system is analyzed from the technical system, the application system, the information interaction system, the control integration system and so on. Through the comparison of various indexes before and after the project, the distribution network can be visually improved in the aspects of security, reliability and convenience of dispatching management after the implementation of the distribution automation scheme. In addition, the social benefit analysis and economic benefit analysis of the distribution automation system are carried out, and the feasibility and maneuverability of the implementation scheme of the distribution automation design are demonstrated.
