摘要
This paper presents a technique for simulation of transient skin effect of the dc railway system based on MATLAB/Simulink. The classic calculation of skin effect based on frequency domain is not suitable for time-domain simulation. The aim of this paper is to develop a time-domain calculation method which can be realized in MATLAB/Simulink. Through the analysis of the step series algorithm, results are applied to the calculation of frequency voltage signal and compared with skin effect impedance of frequency. Accurate simulation of the transient skin effect produces accurate modeling of the remote fault current. This is important for the dc railway protection researchers to develop techniques for discriminating remote short-circuit currents from locomotive starting currents.
