摘要
一套完整可靠的电力设施冰灾监测预警系统可以为各项防灾、减灾、救灾措施提供可靠数据。在极端冰冻气候下,通信网络中断会使现有电力设施冰灾监测预警系统不能发挥预定作用。为此,文章提出了将无线传感器网络应用于电力设施冰灾监测预警系统,结合监测系统的目标与输电走廊的特点,在满足系统覆盖性的前提下,优化了各类传感器节点的部署,设计了一种塔内为底层且塔间为顶层的二层架构网络拓扑结构,同时将小CT取能装置与蓄电池结合,解决了传感器网络节点的能量供给,采用基于查询的路由协议以及相应的数据融合技术提高了数据传输的效率。文中还指出今后可将保证监测系统的可靠性、安全性,解决其与现有电力通信网络的互联问题作为研究重点。
A complete and reliable icing-disaster monitoring and warning system for electric power facilities can offer reliable data for disaster prevention, disaster reduction and disaster relief measures. Under extreme frost climate, due to the interruption of communication network the existing icing disaster monitoring and warning system for power facilities could not complete its predetermined mission. For this reason, it is proposed to apply wireless sensor network （WSN） in icing-disaster monitoring and warning system for power facilities. Combining the objective of the monitoring and warning system with the feature of transmission corridor and under the presupposition of spreadability of the disaster prevention system, the configuration of various types of sensors are optimised and a two-layer network structure, in which the intra-tower is the bottom layer and the inter-tower is the top layer, is designed, at the same time, to supply power to the nodes of sensor network the combination of special CT with accumulator is adopted, meanwhile, to improve data transmission efficiency, the query-based routing protocol and corresponding data fusion technology are used. It also pointed out that how to enhance the reliability and security of monitoring system as well as how to interconnect the monitoring system with existing power communication network could be regarded as key problems to be researched.
