A brief analysis of existing control systems for traction electric drives with induction motors has been carried out, as a result which it established that vector and direct torque are the most promising. The comparative characteristic these according to different parameters drive quality shown in energy-saving algorithms is appropriate use control. work aims simulate system, provides reduction...

Purpose: To develop methodology for determining the actual resistance of traction electric drive (TED) circuits a locomotive with power transmission and refined calculation voltage losses collector-brush apparatus according to microprocessor control system data. These data are necessary calculating characteristics as well its braking in modes. Methods: Methods machine theory, statistical proces...
