Research On Fusion Strategy Of Power Wideband Wireless And Power Line Communication

The parts of intelligent operation and informationization management which contains transmitting, transforming, distribution and consumption electricity are achieved by the smart grid based on composite communication system. Application scene of distribution and consumption electricity is changeable and the network structure is complex, so all the requirements can not be satisfied by only a single wired or wireless technology. Optical fiber, power line carrier and wireless communication should be used for achieving the unified access. In this thesis, fusion access of power wideband wireless and power line carrier communication is researched mainly.This thesis begins with proposing the fusion framework and scheme of power broadband wireless network and power line carrier communication for achieving efficient and reliable transmission of data in simplex network and fusion network basing on the analysis of the key fusion technology of power wideband wireless and power line carrier communication.Then aiming at the requirement of complicated multi-type services of distribution electricity, a switch algorithm of fusion network basing on analytic hierarchy process for avoiding the problems such as data backlog and transmission delay and making the rate/bandwidth of PLC services match that of wireless network is proposed in this thesis.The performances of three kinds of wireless network including TD-LTE, WCDMA and WiFi are analysed and the weights of those are determined so that the appropriate network could be choosen for transmissing services of distribution and consumption electricity preferentially in this algorithm. Finally, the simulations show that the algorithm proposed in this thesis is reasonable and effective.
