【Abstract】 The data measured from practice proves the affections of the electrical railway transformer to Guyuan power system. It is showed that the harmonic current put into the power system from the electrical railway is three phase unbalanced harmonic wave, which bring the negative effects to the power network. So the view that the harmonic wave and negative sequence current should be reduced at the place where it is produced is presented.更多还原
