This paper introduced an algorithm which is used to calculate the traction energy consumption in urban rail transit system. The algorithm of traction energy consumption is based on the train speed regulation model recommended by the CBTC (communication-based train control) system. According to the train speed regulation model, ATC (Automatic Train Control) system calculates the train speed status continuously and then sends the current commands to train tracking/braking system. Then the relationship of the train speed status, traction energy and the regenerative braking energy can be established on the specified civil and vehicle situation. With the help of precise calculation of energy consumption, optimized strategy of energy saving can be built.
