Development of Computer Program for Calculation of Induced Lightning Voltages on Overhead Multiconductor Systems

다상 가공선로의 유도뢰 전압 해석을 위한 프로그램 개발

A program for numerical analysis of induced lightning surge is developed. The program first converts simultaneous differential equations into simultaneous difference equations for line sections without transition points, and calculates the line voltage and current by solving a determinant. It, then, calculates the line voltage and current at transition points by applying kirhhoffs law. This program is potentially useful in a wide range of applications for investigating the effect on distribution lines of lightning protection equipment such as lightning arresters and overhead ground wires.
