Simulation of lightning surges on tower transmission using PSCAD/EMTDC: A comparative study

Abstract

This paper describes the analytical and the experimental responses of the surges strike on the transmission line towers. A new method of calculating transmission tower surge response has been proposed. It has been found that the tower surge response calculated by the proposed method has a close agreement with the measured tower surge response obtained from scale model and field tests. Without the use of simulation program, this topic might be difficult to understand. PSCAD/EMTDC has been selected as the software used to generate the appropriate data needed to graphically demonstrate this phenomenon.

Study on the calculation of shielding failure for dc transmission lines

“…The former means that the lightning hits the transmission lines across ground wires, and the latter means that the lightning hits the tower and then causes the insulators flashover. The traditional solution of shielding failure is to use the electro‐geometric model, which means modelling the structure of transmission lines into the electrical geometric model [9, 10]. The original model was obtained according to the operating experience of 110 kV transmission lines on the plains, but present towers are higher, so the calculation error using this model can be unacceptable.…”
