Abstract: To overcome the problem in currently studying train energy saving operation optimisation, the speed is selected as the design variable to establish the objective and constraint functions and train energy saving operation optimisation model. Taking a route optimisation as an example, the program of train energy saving operation optimisation based on MATLAB language is developed, and optimisation solution is accomplished by using the sequential quadratic programming (SQP) algorithm. Then, the distribution of each interval endpoint speed is obtained and the optimum speed-distance curve is designed. Optimisation results show that this handling research method is feasible and effective.

Keywords: urban rail transit; energy saving; operation optimisation; SQP algorithm; MATLAB.
