Online Monitoring of Wind-Induced Vibration of Transmission Steel High Tower

Abstract

For transmission steel high tower, wind-induced vibration is significantly increased because of its high height and flexibility. Long-term vibration may damage tower and conductor. Thus, it is necessary to enhance ability of supervision the vibration and take measures to control it to allowable extent. In the paper, a method to achieve wind-induced vibration characteristics of high tower is studied using technologies of environmental incentive of wind load and wireless sensor acquisition and transmission signals. Monitoring device and sensor are designed to acquire meteorological environment parameters and tower vibratory responses. Parameters of tower vibration are analyzed and determined based on a monitoring system. The technologies are used for monitoring the wind-induced vibration of a large-span steel tubular high tower. It is demonstrated that the technologies put forward are practicable and suitable for field working condition, and present good effects.
