 Ice shedding occurs frequently on overhead transmission line in ice area. The line vibration caused by ice shedding may reduce the structure safety of transmission tower. In order to implement the experiment simulation for the ice shedding of transmission line under multi-operating conditions, this paper develops a new nonlinear simulation experiment system of ice shedding for overhead transmission lines based on bus architecture design, which consists of ice shedding simulation module, ice shedding control module and data acquisition module. The ice shedding simulation module establishes the fundamental environment of the experiment, which can design according to different transmission line conditions. The ice shedding control module sets the time sequence of ice shedding, which can accurately simulate different ice shedding conditions according to the time sequence. The data acquisition module acquires the dynamic tension in real time, and adopts binocular stereo vision technology for the measurement of ice shedding jump track of the overhead conductor. The system has a higher lever of automation and a good control precision, which can effectively obtain the dynamic tension and ice shedding track during ice shedding.
