Modelling and Simulation of High Voltage Direct Current Magnetic Moment Driving Deicing Method

Abstract

In view of the high voltage transmission line icing, the deicing method of magnetic torque driving deicing cutters is proposed for the first time based on magnetic field of HVDC: The ampere torque in the magnetic field produce by the HVDC is used as the rotary drive, replacing motor, providing a magnetic torque to drive the deicing mechanism. The physical model to achieve drive of magnetic torque is established by analyzing the magnetic properties around the HVDC transmission lines and the demand for magnetic torque of the robot. Magnetic torque is theoretically calculated as well as the relationship is analyzed between it and the model parameters.Having a comparison and analysis between the magnetic torque calculated theoretically and the simulation results after the use of software, the results turn out that the proposed method of drive system of magnetic torque in this paper is practical and it will play an significant role in the physical implementation of magnetic torque drive system for deicing robot.
