PROJECT TITLE :

Energetic Macroscopic Representation of a Marine Current Turbine System with Loss Minimization Control - 2017

ABSTRACT:

This paper presents a detailed modeling together with an lively macroscopic graphical illustration of the marine current turbine (MCT) system. The MCT system beneath study consists of a 1.five-MW mounted pitch turbine, a permanent magnet synchronous generator, an ac-dc absolutely controlled machine facet converter, a dc link, a dc-ac absolutely controlled grid-facet converter, association cables, a transformer, and the main grid. The management of every converter is intended by considering the tuning chain as a part of the system's energetic macroscopic representation. The machine side converter's management makes use of the maximum power point tracking torque control and also the generator loss minimization (output maximization) techniques to boost the efficiency when the system runs below the rated marine current speed. When the system runs above the base speed, the management mode is switched to the rated power limiting mode. The grid-facet converter is controlled to stabilize the dc-link voltage within a bound range besides controlling the reactive power. The proposed management ways are evaluated primarily based on the model results by using the important data of The Alderney Race (Raz Blanchard in French) marine web site.
