Electromagnetic Analysis of a DFIG‘s Controlled Operation Using Finite Elements Method
摘要
The Doubly Fed Induction Generator (DFIG) is widely employed in wind energy and this type of source is interesting to the smart grids environment. In this way, this chapter proposes an electromagnetic analysis using the finite element method for the DFIG based Wind Energy System, during its vector controlled operation by means of a proportional-integral (PI) controller. Moreover, a new design method for the PI controller gains obtention is presented, based on the fact there is no guarantee that the DFIG will operate in the unsaturated condition. Therefore, it can compromise the performance of the power control strategy. Simulation and experimental results endorse the analyzes during DFIG normal operating conditions.
