Abstract :
[en] Regarding renewable energy and environment- friendly issues, wind energy nowadays has become the fastest-growing energy source in the world, and thus attracts a lot of research interest in the wind turbine generation system. A doubly fed induction generator (DFIG) is used for variable speed operation in a wind turbine system to extract more power. Following a systematic approach, this paper investigates on the modelling and simulation of wind turbine generating systems using the flexible multibody simulation software SAMCEF/MECANO [1]. The objective of this work is to analyze the control-generator-structure interactions in a wind turbine system. Firstly, an extension of the finite element method is integrated into the flexible multibody dynamics solver, and thus extends the solver to represent mechatronic systems in a strongly-coupled way. Secondly, DFIG and the control systems are modularly modeled for the wind turbine package. Control of DFIG for grid synchronization and power optimization are elaborated in detail, and the methods are validated through a 2MW DFIG wind turbine prototype model. At the end, a systematic system model of wind turbine structure connected with the DFIG generating system is presented, which provides the dynamic analysis for the whole system in an overall range.
