In the full use of the measured data of Guangzhou Metro, this paper proved the time constant is changing with the development of the short circuit process through establish an appropriate short circuit calculation model; at the same time, it made a deep theoretical analysis about skin effect, and did some correlation simulation research by simplify the actual situation; on the basis of the simulation results, the paper summarized the change of resistance and inductor parameters of metro rail line under the influence of skin effect with frequency changes.
