Research on Wind Deviation Monitoring Technology of Transmission Line based on Millimeter Wave Radar

The wind deviation phenomenon of transmission lines has become one of the important reasons leading to grid tripping. Effective wire wind deviation monitoring is an important part of transmission line condition monitoring system. Due to the limitation of previous techniques, the current wind deviation monitoring is still difficult to accurately measure the interphase distance of the conductor. With the continuous development of millimeter wave radar technology, it provides a new technical route for wind deviation monitoring. In this paper, the hardware design of the radar is carried out based on the 24GHz band millimeter wave radar chip, aiming at the direct and accurate measurement of the interphase distance of the wire. A software algorithm optimization process based on frequency-modulated continuous wave is proposed to meet the demand of wind deviation monitoring. At the same time, the millimeter wave radar module and wire monitoring sensor are integrated. Compared with the traditional method, the direct and accurate measurement of interphase distance is realized, which effectively improves the technical practicability of wire wind deviation measurement.
