FIELD: transportation.
SUBSTANCE: method for protection against slippage and skidding of wheel pairs of electromotive train with valve-inductive electric drive consists in the fact that when slippage (skidding) of one or more wheel pairs appears control signals are generated which change electric drive system operating conditions. In this method engine control with fixed value of voltage impulse duration supplied to engine winding is changed to synchronous mode. This lets to prevent development of excess wheel pairs slippage process and realise drive operation mode which is marginal by adhesion conditions.
EFFECT: enhancement of traction or braking properties of electromotive train.
