DESIGN OF MONITORAND PREDICTION SYSTEM FOR HIGH VOLTAGE TRANSMISSION LINE GALLOPING

摘要

Galloping is a disaster of transmission lines. It is a large-amplitude, low-frequency mechanical vibration that occurs on transmission lines under a combination of wind, ice-covered lift, and wire tension under specific weather conditions. At present, an online monitoring system with a single sensing method is widely used in the power grid. There is still relatively little research on the prediction of galloping disasters. This article designs an online monitoring and prediction system that combines video monitoring and inertial navigation modules. In the system, the data fusion method is repeatedly used to achieve more accurate on-line monitoring and short-term prediction of transmission line galloping.
