dc.description.abstractIn article analyzing typical electrical locomotives were manufactured with analogous control systems (2M62, TEP-70) of the entire power train and electric drive, which have a lot of deficiencies. The major deficiency was high fuel consumption. The locomotive traction force Fk = f(v) for the theoretical traction requirements must be inversely proportional to the movement speed v. This characteristics is called hyperbole, it allows optimum control of the locomotive in the entire speed range, i.e. to use the diesel engine power to its full extent. Once such locomotive traction characteristics are created, the diesel engine capacity in the hyperbole characteristics is constant. To solve this task the traction characteristics Fk = f(v) and traction generator load characteristics Ug = f(Ig) must be hyperbolic shape. In order to improve energy characteristics of diesel-electric locomotives 2M62, TEP-70, analysis of their automatic control systems was performed. Based on this, the systems which were proposed by the authors and implemented, have enabled significant reduction of fuel consumption, improved driver's working conditions, traffic safety, etc. Especially important technical tasks to be solved were to improve general reliability of locomotives, and to reduce operation costs. The authors have proposed not to use special electric machines for excitation of traction generators, but to replace them with contactless semiconductor static converters and to use microprocessor based locomotive parameters control systems.en_US
