A study on the Line impedance calculation method in electrified railway system
전기철도에서 급전선로의 line impedance 계산에 관한 연구
Abstract
Transmission line impedance calculation has been tried for obtaining exact value. The method proposed by Carson contains indefinite complex integral. Although the Carson solution is proposed with power series, the solution is limited and valid at special range of frequency. In this paper, we proposed a simplified Carson solution by analytical method using ground transmission line return current. This method calculate the transmission line impedance easily.
