FIELD: electricity.

SUBSTANCE: method of main motor braking and reverse control consists in alternate regenerative braking of the ship engines. The regeneration of the braking energy is carried out through the DC link by controlling the connection of the links by means of signals from the upper level system depending on the ship speed and the amount of recovered energy of the main motors. A uniform transfer of recuperative braking energy is made through the DC link of each electric motor between all the electric motors of the ship. With the help of the predictive model of the braking and reversing mode of the main motors of the ship, taking into account the current and predicted parameters of the ship's motion and the elements of the unified electric power system, the optimal braking parameters are determined: braking sequence, start time and speed of braking and acceleration of main motors, parameters of generator sets of the power plant.

EFFECT: optimisation of the ship braking with two or more adjustable main motors of the ship.
