Research on Architecture of Terminal Communication Access Network in Smart Grid

For a long time,the distribution automation and AMR services have not been widely implemented in China.One of the most important reasons is the poor communication system in distribution network.The poor performance and low reliability of the communication system restricted the development of distribution network.As the promotion of smart grid,the services in distribution network have increased greatly.Most of them require high-speed,real-time,reliable communication as support.This paper proposes a new architecture of distribution communication network which is suitable for smart grid,through studying the distribution network communication services and analyzing the existing problems of distribution communication network architecture.
