基于阶跃级数逼近法的城市轨道交通钢轨短路电流趋肤效应研究
Research of Short-Circuit Skin Effect Current of DC Railway Based on Step Series Algorithm
摘要
Abstract
With the solution of Bessel function for equivalent circular cylinder conductor of rail,the current response of unit step voltage applied on rail was analyzed.Based on this solution,calculation method of skin effect in time domain with voltage step series was offered,and rail short-circuit model is build by S-Function with Matlab/Simulink.At last,this paper uses frequency calculation and short-circuits test to prove the validity of the calculation method.关键词
