认知无线电在智能电网中的应用研究

摘要

Combined with the up-to-date theory of smart grid construction at home and abroad, the design and implementation of smart grid wireless communication system based on cognitive radio are discussed. Firstly, the multilevel structure of smart grid wireless communication system is studied, and the network classification, wireless communication technology in each classification and access strategy of cognitive radio users are analyzed. And then the issues and key technologies in system implementation are analyzed in depth. At last, some research ideas for the network structure of power transmission and transformation, the access strategy based on priority and the construction of Ad hoc emergency network based on cognitive radio are put forward.%结合国内外最新的智能电网建设理论，探讨了基于认知无线电技术的智能电网无线通信系统的设计和实现。首先研究多级的智能电网无线通信系统结构，对网络分级、每一级的无线通信技术和认知无线电用户的接入策略进行分析；然后通过对系统实现面临的问题以及需要解决的关键技术进行深入分析，提出了完善输变电网络结构、基于优先级的接入策略、组建基于认知无线电技术的Ad hoc应急网络等研究思想。
