Calculation of energy - saving traffic of tram vehicle with field - oriented control of traction induction motors

The paper deals with the problems of the tram vehicle control according to the criterion of the minimum electric energy consumption. The authors have extended the methodics given in literature and have elaborated the algorithm of the energy-saving tram traffic taking into consideration various ride disturbances. During the running within the framework of the city conditions tram ride parameters change frequently. The mathematical models take into account the field-oriented control of traction three-phase squirrel-cage induction motors. Determination of the run algorithm ensuring the minimization of the electric energy use has been realized by application of the optimization procedure.
