Abstract
AC electric railway feeding system classifies into three groups such as normal, TIE and PP feeding method. If the feeding scheme of ac electric railway is changed, current distribution flowing through the line is also modified. And if the current distribution is altered according to the feeding scheme, returned tendency through rail load current or fault current of the train is changed. So the investigation about error correcting method of protective relay is needed considering feeding scheme. In this paper prior to error correcting of protective relay, through interpreting feeding circuit, changes in current distribution of the rail in accordance with feeding would be predicted and analyzed.
