Study of failures in Wind Turbines with Permanent Magnet Synchronous Generator

The development of offshore wind farms around the world is increasing significantly due to the need to decarbonize electrical energy systems. The implementation of wind turbines with permanent magnet synchronous generator (PMSG) in these wind farms is remarkable. Since wind turbines become more powerful every year, it is important to improve maintenance plans and to prevent failures in order to keep reduce downtime. In the case of offshore wind turbines, the logistics required to carry out repairs considerably increase the operating costs. This way, it is important to develop strategies that reduce operation and maintenance costs and increase the lifetime of the equipment.This work was developed to analyze the main failures that occur in PMSG-based offshore wind turbines, and the state of the art regarding failure modeling and simulation. The most common and critical faults of the PMSG-based wind turbines have been considered, which are usually in the power converter and in the electric generator. The objective is to integrate the analysis into a model of an offshore wind turbine and to develop a working digital twin.
