摘　　要：当前采用无线传感器网络对输电网进行低成本监控存在一些技术难题,其中低功耗、低数据速率设备是其带宽和延迟的瓶颈。文中的目标是设计出能够实时进行物理测量的无线网络,通过制定一个网络设计优化问题,目的是尽量减少安装与运营成本,同时满足数据流的端到端延迟与带宽限制。通过研究由有线、无线和蜂窝技术组合而成的混合分层网络架构,以保证低成本的实时数据监控。基于所设计的模型,文中对各种场景进行优化评估。由此分析表明,使用WSN的电网无线监视系统是可行的,同时无线链路带宽可能是成本优化的一个限制因素。At present, the low cost monitoring of the trans- mission network using the wireless sensor network still has some technical problems, among which the low power consumption and low data rate of the equipment constitute the bottleneck of its bandwidth and delay. The goal of this paper is to design a wireless network that can perform real-time physical measure- ments and formulate a network design optimization issue, which aims at minimizing installation and operation costs while satisfy- ing the end-to-end delay and bandwidth limitation of the data flow.The hybrid hierarchical network architecture composed of wired, wireless and cellular technologies is studied to ensure the low cost real-time data monitoring. Based on the designed mod- el, various scenarios are optimized and evaluated. The analysis shows that the wireless monitoring system using WSN is feasi- ble, and the bandwidth of the wireless link may be a limiting fac- tor for cost optimization.
