- Abstract
A mathematical model is developed of a fragment of an electric power transmission system whose key part is a long ultra-high voltage power line including lightning protection cables of distributed parameters. The model is based on a long line second-order partial derivative equation. The boundary conditions of the second and third types (Neuman and Poincare conditions) are used for the purposes of the equation. The line equations are solved by discretising partial derivatives using the straight-line method and then integrating the latter with the fourth-order Runge-Kutta method. Simulation results are given in a graphic format analysed in the state of two-phase short-circuiting.
