This paper focuses on the study of the modelling of an offshore wind architecture based on a 15MW doubly excited synchronous generator (DESG). This architecture’s peculiarity is its design to be simple, efficient, and less expensive than previously proposed architectures. Designing and implementing a wind turbine requires a detailed model of the energy conversion system. It enables understanding and predicting the system behaviour under different operating conditions. Our modelling approach for the wind conversion system will be presented in this paper, with descriptions of the different power electronics components. The results of our proposed architecture and the analyses that were derived from it will be discussed at the end of this paper. This article demonstrates that the electric generator designed can operate independently even if there is no external energy source, which makes our proposed wind architecture competitive in the market, thanks to its low cost, efficiency and simple power electronics.
