摘要：
Introduction The rise of ultra-high voltage AC grids creates corona noise, which is crucial for assessing transmission line environments.Methods This paper analyzes corona noise distribution around AC transmission lines using a 3D model for quantitative assessment. We employ the Finite Element Method, and factors like electric field intensity, conductor splitting, and sag are considered. Corona noise is calculated using CEPRI prediction equations and validated with field data.Results We found strong corona noise concentrating within a 20 m lateral and 240 m vertical radius. Within 50 m, lateral attenuation is 3.6%, and longitudinal attenuation is 3.3%.Conclusion This research provides insights for monitoring and controlling corona noise in transmission line design and operation.
