摘　　要：分析目前各种输电导线防舞措施和一些防舞装置的优缺点，本文基于输电线路舞动三自由度模型设计了输电线路在线监测防舞预警系统，该系统利用三自由度模型仿真提取导线舞动轨迹的轨迹，结合历史资料和在线监测的实测数据实时对导线舞动的情况进行监控，在接近极限值时发出预警并采取处理措施，防止倒塔。According to the analyses of the advantage and disadvantage of anti-gaUoping method and instaUation, a real-time monitoring anti-galloping and pre-alarming system of transmission line＇s galloping based on Three-DOF Model is developed in this paper. Maximum amplitude of galloping lines is extracted by 3-DOF model simulation. The system combining with weather forecast and measured data can issue a warning to the safety of transmission fines running ahead of time
