The identification of shielding failure and back striking in transmission lines is always difficult. The process of back striking and shielding failure in UHVAC transmission lines was analyzed in this paper. Because the mechanisms of produced transient zero module current and its propagation paths were different between back striking and shielding failure, their wavelet energy of different frequency...
Lightning stroke to transmission lines was introduced in this paper. Modeling and implementation method of tower, corona and insulator for lightning electromagnetic transient research was discussed. Comprehensive model for study of UHVDC lightning electromagnetic transient was built, and lightning caused fault and lightning disturbance were simulated in PSCAD/EMTDC based on the model, which offered...
