摘要

根据配电网系统结构和设备分布特点，给出了一种基于无线传感器网络（WSN）的配电网监测数据通信网络架构。针对电力工业通信规范对WSN的要求，建立了基于IEEE 802.15.4标准媒体访问控制（MAC）层协议并引入服务质量（QoS）的QoS-MAC模型，给出了配电网监测节点数据缓冲队列马尔可夫链模型和各节点竞争信道状态概率计算方法。为衡量配电网WSN的性能，建立了节点MAC层具有QoS支持的载波侦听多点接入/冲突避免（CSMA/CA）信道冲突率模型、传输延时模型、网络有效数据吞吐率模型，设计了网络分析测试环境。在不同的配电网数据产生率下，对所提出的QoS-MAC协议网络传输性能进行了测试分析。实际应用表明所提出的方法可为配电网数据监控提供有效的QoS服务。

Abstract

According to equipment distributional characteristics and structure of distribution power grid（DPG）， a DPG monitoring communication network topology based on wireless sensor network（WSN） is introduced. By analysis demand of DPG monitoring and control data， an enhanced QoS-MAC model based on IEEE 802.15.4 protocol is built for WSN requirement of power industry communication specification. The model is expressed by node buffers Markov chain model and wireless channel probability calculation model for providing QoS. In order to analyze WSN performance of DPG， CSMA/CA channel collision model， communication time-delay model and network data throughput model in MAC layer supported by QoS are calculated. The network analysis scenarios for distribution devices communication are also designed to analyze the network performances for QoS-MAC under different distribution data rates. The analysis and application results show that the method proposed can provide effective QoS for DPG monitoring and communication control.
