Networking design of wireless sensor network for typical application scenarios of intelligent distribution networks

无线传感器网络因具有低功耗、大规模、低成本等优点,使其在智能配电网中有着广阔的发展前景。无线传感器网络拓扑结构和通信协议种类繁多,但依然存在功耗大、寿命短、信号质量差、传输距离近等问题。针对此问题,首先,设计了配电站房、柱上变压器、箱式变压器三种典型应用场景中无线传感器网络的整体结构,针对智能配电网无线传感器网络寿命短的问题,考虑传感器重要等级和设备健康状态提出了簇头节点的选取与更新策略;其次,针对智能配电网无线传感器网络通信信号质量差的问题,提出了基于433 MHz的智能配电网星型无线传感器网络拓扑结构;最后,完成了智能配电网典型应用场景中无线传感器网络的组网设计。

Wireless sensor network(WSN)has a broad prospect in intelligent distribution network because of its advantages such as low power consumption,large scale,and low cost.There are many kinds of WSN topology and communication protocols,but there are still problems such as difficulties in development and maintenance,poor signal quality,and short transmission distance.This paper first designs the overall structure of WSN in typical application scenarios of power distribution station building,column transformer and box transformer.Aiming at the problem of short service life of WSN in intelligent power distribution network,the selection and update strategy of cluster head node is formulated.Secondly,the problem of poor communication signal quality of WSN in intelligent power distribution network is addressed,the network topology optimization model of star type WSN-433 MHz is selected to optimize the wireless network topology.Finally,the networking design of WSN in intelligent distribution network is completed.
