ABSTRACT: Galloping of power transmission lines might
bring about huge damage such as massive power outage and collapse of the
transmission towers. To realize forecast of the galloping and provide data for
study on the galloping mechanism, this paper proposes an online monitoring
system for tracking galloping profile of power transmission lines based on
wireless inertial measurement units (WIMUs). The system is composed of three
modules: wireless inertial measurement nodes, monitoring base station, and
remote monitoring station. After detailing the hardware system, the
corresponding software which positions and displays galloping profile of the
transmission line in real-time is outlined. The feasibility of the proposed
on-line monitoring system is demonstrated through a series of experiments at
the State Grid Key Laboratory of Power Overhead Transmission Line Galloping
(Zhengzhou, China) by taking into account different vibration patterns.
