Power distribution and utilization communication network for smart grid

Based on the up-to-date theory for the construction of smart power communication network home and abroad, the concrete planning, design and implementation of the construction of power distribution and utilization network are researched. Firstly, the related services of smart power distribution and utilization network and the relation among services and demands of service communication are analyzed, and basic service network models corresponding to various types of services are constructed; then in the viewpoint of the development of the network merging multi services, key technical elements related to the construction of communication network merging four kind of services such as available communication technology, structure of communication protocols, technology of synthetical network management and network security technology, are analyzed; finally based on the experiences of actual construction a typical infrastructure based on multi-technological networking, which can support following services: advanced distribution automation, acquisition of power utilization information, video surveillance and environment monitoring, bi-directional information communication between power suppliers and consumers and temporary emergency communication, is put forward, and corresponding typical technical implementation scheme for the construction of such a communication network is given.
