摘　　要：对于配电网输电线舞动的有效防护,可以在一定程度上降低舞动所导致的一系列损失,通过研究一种采用多源传感器的高压配电网输电线舞动检测系统,来有效防止输电线舞动。该系统中最主要的部分为感应器、无线全球移动通信系统(Global System for Mobile Communications,GSM)模块以及数据采集终端,根据传感器可以准确地计算出输电导线间舞动的间距和高度,使用GSM功能则能将所测量的信息无线传送到系统的值班监测机上。在实验室的模拟实验中,该系统可以更加精确地监视和检测交流输电线保护的舞动振幅。经过实际应用,目前最新设计的输电线保护舞动监测设备价格相对便宜、操作简单、结构紧凑,性能基本可以满足输电线舞动监测系统的需求。Effective protection of transmission line galloping in distribution network can reduce a series of losses caused by galloping to a certain extent.By studying a detection system of transmission line galloping in high voltage distribution network using multi-source sensors,transmission line galloping can be effectively prevented.The most important parts of the system are sensors,Global System for Mobile Communications(GSM)modules and data acquisition terminals.According to the sensors,the galloping distance and height between transmission wires can be calculated accurately,and the measured information can be wirelessly transmitted to the on-duty monitoring machine of the system by using GSM function.In the laboratory simulation experiment,the system can monitor and detect the galloping amplitude of alternating current transmission line protection more accurately.After practical application,the latest design of transmission line protection galloping monitoring equipment is relatively cheap,simple to operate and compact in structure,and its performance can basically meet the needs of transmission line galloping monitoring system.
