Dynamic Lightning Hazard Risk Assessment Method for 10 kV Distribution Networks Considering Multiple Influencing Factors
摘要
Abstract
To address the limited applicability of existing lightning risk assessment methods for transmis-sion networks in distribution networks,the author proposes a dynamic lightning risk assessment method considering multiple influencing factors for 10 kV distribution networks.The method comprehensively in-tegrates multiple influencing factors,including line parameters,building distribution,surface water bodies,soil types,lightning ground flash density,and lightning current amplitude distribution.A com-prehensive calculation system for lightning flashover rates is established,encompassing direct lightning strikes,induced lightning overvoltages,and building shielding corrections.A deep learning-based se-mantic segmentation model is adopted to automatically extract building outlines and surface water informa-tion from high-resolution remote sensing imagery,enabling the dynamic update of geographical parame-ters.Combined with the monitoring data of lightning location systems,lightning activity parameters are acquired in real-time to support the dynamic assessment of regional risks.Using a 1 km × 1 km grid di-vision and range normalization,regional lightning risk maps are generated.An empirical application was conducted in the Beijing area as a case study.The results obtained in the Huairou,Miyun,and Pinggu districts verify that the proposed method can effectively reflect the actual distribution characteristics of re-gional lightning risks.This approach provides a systematic theoretical basis and a practical tool for differ-entiated lightning protection planning and operation and maintenance management of 10 kV distribution networks.关键词
