Khvorost M. The improvement of the regulation system of the tractive engines in subway cars for the decreasing of uneven distributions of electric current.

The dissertation is devoted to the complete use of tractive electric engines in subway cars. It the dissertation the assesment criteria of the functioning of regulation system of tractive engines the use of electric power and to increase the quality of traction and braking have been worked out. The maximum value of uneven distribution of electric current has been determined. The main causes of uneven distribution of electric current in tractive engines have been revealed. The regulation system for equalizing electric current in the parallel chain of electric engines has been worked out. The new system has been tested upon the physical model as well as in operation conditions. The interdependance between the amount of electric power and the value of uneven distribution of electric current has been determinated.
