Finite Element Analysis and Overvoltage Protection of 10kV Continuous Tilt Overhead Line in Pumped Storage Power Station

For the 10kV voltage level line lightning protection configuration is weak, can't provide a complete lightning protection measures, established a pumped storage power station continuous tilt overhead line simulation model; Established the spatial distribution model of the tilted overhead tower, and use the finite element method to analyze the maximum space induced electric field strength of the tower at all levels. Using the ATP-EMTP to establish the parameter model of the tilted overhead line, for the different tower of the induction electric field strength, analysis of the installation of lightning arrester in different locations, the shielding failure and back striking protection effect, while providing guidance for the engineering transformation.
