摘　　要：基于先进传感、信息通信的输变电设备运行状态在线监测技术已成为电力系统的发展趋势.输电线路状态在线监测网络具有链状、数据传输量大和传输距离长等特点,能量热区问题显著.为均衡输电线路在线监测中无线传感器网络的能量消耗,提出了一种基于同步变距的全局能量均衡路由算法EBRA-SVD.采取多个子网络方式,缩短数据传输距离,从而缓解长距多径损耗而产生的"能量热区"问题.仿真显示,EBRA-SVD可有效均衡网络能耗,提升网络寿命.The advanced sensing and information communication based on-line monitoring technology of transmission and transformation equipment has become the development trend of power system.On-line monitoring network of transmission line has the characteristics of chain,large amount of data transmission and long transmission distance,and it has an obvious problem in energy hot area.In order to balance the energy consumption of the wireless sensor network in the online monitoring of the transmission line,this paper proposes a global energy-balanced routing algorithm based on synchronous variable distance,EBRA-SVD.EBRA-SVD adopts multiple sub networks and shortens data transmission distance,thereby alleviates the"energy hotsport"problem which caused by long distance and multipath loss.Simulation shows that EBRA-SVD can effectively balance network energy consumption and prolong the lifetime of network.
