摘要
无线通信是智能配用电通信的重要手段.在智能电网无线通信中,230数传电台和新型电力无线专网通信并存,认知无线电的频谱感知技术是解决两个系统共存的关键.以230数传电台为主系统,新型电力无线专网为从系统,研究感知时间对频谱感知准确性的影响,进而研究对从系统的高可靠性传输所需重传次数的关联影响.通过优化从系统中智能终端一个工作周期内感知和传输时间的比例,总体系统的高可靠性业务数据吞吐量得以最大化.
Wireless communication is one of the important methods in smart power distribution and utilization communication system.230 data transceiver system and a novel power private communication network will coexist in smart grid communication infrastructure.Spectrum sensing in cognitive radio is the core technique to solve the problem.In this article,230 data transceiver system is regarded as the primary system and the nova private communication system is regard as secondary system.Effects of sensing time to sensing accuracy and change in re-transmission time for high reliability service are researched in this article.By changing the ratio between sensing and transmission time during a working period of smart terminal equipment in the grid,the system overall throughout of high reliability service will be maximized.
