提出了将无线传感器网络应用于智能箱式变电站的监测系统，给出了基于无线传感器网络的智能箱式变电站组网方案。同时采用小CT取电装置从箱内线路上取电和电池供电相结合的方法，有效地解决了传感器节点的供电短缺问题，采用两层三簇式拓扑结构减少了路由跳数、提高了传输效率。最后以变压器室的监测系统为例，探讨了如何优化传感器节点的布置，指出今后可将箱变设备本身的智能化建设、网络安全和时钟同步问题作为研究重点。%The monitoring system of wireless sensor network applied in the intelligent package substation is presented and network schemes of intelligent package substation based on wireless sensor network are given in this paper. At the same time,the power supply shortage of sensor node was effectively solved with the combination power supply method of small CT device taking power from box line and the battery,and the routing hops were reduce and the transmission efficiency was improved by using the two-layer and three-cluster of network structure. Finally,taking the monitoring system of transformer room as an example,the paper discussed how to optimize node layout of the sensor,and also pointed out that the intelligent construction of the box substation equipment,network security and synchronous problem of clock would be the research focus in the future.
