In the paper there are presented and tested energy-efficient algorithms of asynchronous drive control with the system of moment direct control on the basis of simulation. The algorithms are directed to the reduc-tion of stator current consumption and also to the maximum use of an engine on heating and power. With purpose of energy saving the electric drive system with direct moment control is supplied additionally with a special setting device of a stator flux linkage where the dependence of a stator flux linkage upon the moment of an asynchronous drive necessary to support an optimum angle between momentforming vectors is realized. A functional scheme of the system of an energy effective doublearea control of an asynchronous drive velocity with the direct control of a moment and an adjustable capacity limitation reflecting principles of functioning and an interrelation of system basic units is shown. To check-up the solutions offered there is developed a model of a traction electric drive system in the basic library of the bundled software Matlab Simulink, the results of its modeling confirm the effectiveness in the application of energy saving algorithms allowing the reduction of current consumption of the asynchronous traction electric drive by 7-10%
