Tractive energy optimization in railway electric traction system

Abstract

The modern high speed railway traction system consumes a lot of energy from the supply line due to high current drawn which increases the cost of travel. The optimization of energy consumption without affecting the maximum speed of the train is desired. This paper deals with the tractive energy consumption in railway traction system and optimization of the same. Various parameters of interests (e.g. acceleration; acceleration period; free run period) corresponding to optimized energy has been calculated. The intelligent and evolutionary optimization techniques have been used to determine optimized tractive energy.
