面向配电网故障检测的无线传感网络可靠路由方法

A Reliable WSN Routing Method for Distribution Network Fault Detection

针对配电网故障检测系统对无线传感器网络路由可靠性要求较高的问题,设计了一种面向配电网故障检测的无线传感器网络(wireless sensor network,WSN)拓扑结构,并提出了一种面向配电网故障检测的WSN可靠路由方法。其首先根据最小跳数路由方法为每一个节点分配值,之后在节点选择下一跳最优节点时考虑路径损耗以及能量损耗,并可以根据配电网故障检测业务合理调节权值来分配可靠性与能耗性的比重。仿真及实验结果表明,RRFD路由方法与传统路由方法相比,可靠性显著提高的同时有效降低了能耗,适用于配电网故障检测场景。

Distribution network fault detection system requires high route reliability for wireless sensor network（WSN）. For this reason, a WSN topology for power distribution network fault detection was designed and a Reliable WSN Routing method for distribution network Fault Detection（RRFD） was proposed. The method firstly assigned Hop value for each node based on minimal Hop algorithm and selected optimal node considering the next-hop path loss and energy loss. The weights to allocate reliability and energy consumption could be reasonably adjusted according to distribution network fault detection demand. Results of simulation and tests verified feasibility of the proposed topology of novel RRFD. Comparing with traditional routing method, novel RRFD can reduce energy consumption and dramatically improve reliability, thus it is suitable to distribution network fault detection.
