Abstract

In high-altitude regions with high wind speeds, irregular wind-induced ice shedding on OPGW (Optical Ground Wire) severely affects the normal operation of power systems. Addressing the impact of typical crescent-shaped ice cover on OPGW wind load body shape factors, this paper employs computational fluid dynamics to simulate the airflow around the conductors. Numerical simulations are used to calculate how the aerodynamic coefficients vary with wind attack angles under different wind speeds and ice thickness conditions. The results indicate that increasing ice thickness does not alter the trend of aerodynamic coefficient variations but significantly affects their values. The aerodynamic coefficient initially increases and then decreases with the wind attack angle, reaching maximum values at 90° wind attack angle when the windward area is largest.
