Динамічна модель гребної дизель-електричної установки з уніполярними машинами

The article presents an improved dynamic model of a diesel-electric propulsion unit with unipolar machines, which, unlike the known ones, takes into account the presence of three control loops that form the magnetic fluxes of the generator, the propulsion electric motor, the speed of the diesel engine and one control (output) variable: the speed of the propeller, which allows for the synthesis of control loop regulators with given dynamic characteristics. When constructing ship electrical power systems, single ship electrical power systems are widely used, which combine a significant set of electrical devices that can be functionally divided into devices that provide electricity for the ship's own needs and systems that provide movement and are called propulsion electrical units. The purpose of the article is the need to improve the dynamic model of a diesel-electric propulsion unit with unipolar machines, which will allow for the synthesis of control loop regulators with given dynamic characteristics. The research used GRC as the engine. This article considers the elements of a diesel-electric propulsion plant from the perspective of dynamic systems theory, on the basis of which a mathematical model of a diesel-electric propulsion plant is developed. A dynamic model has been constructed that has three control loops that form the magnetic fluxes of the generator, the propulsion electric motor, the diesel engine rotation speed and one control (output) variable: the propeller rotation speed. This system will subsequently allow for the synthesis of control loop regulators that meet the specified optimization criteria
