Abstract: This work presents the implementation of a wind energy conversion system based on a Double Fed Induction Generator (DFIG), driven by a DC Motor (DCM), which emulates the transient and steady state characteristics of a wind turbine. The experiments present the transient of the transfer of active and reactive power between the power grid and the DFIG during hypo and hyper synchronous modes. The control algorithms are implanted in C, using dSPACE DS1104 control board to drive both machines. The experimental results confirm the advantages of using this structure for wind energy conversion system and the effectiveness of the control algorithms.

Abstract: En este documento se presenta una descripcion del generador eolico de la configuracion DFIG para conocer su estructura, funcionamiento y principales inconvenientes que se producen al momento de conectarse a una Micro-red. La implementacion esta basada en un modelo de 13 barras con generacion distribuida citado del IEEE en modo conectado a la red principal, se plantea tres casos de estudio para visualizar diferentes escenarios y de esta manera obtener mejores resultados en el analisis del comportamiento DFIG en una Micro-red. Adicional se va emplear cargas con valores maximos y minimos que permitira realizar una mejora en el filtro del modelo DFIG. Se realiza un analisis comparativo tomando en cuenta dos aspectos, los niveles de voltaje en todas las barras y la presencia de armonicos de orden 3, 5, 7, 9, mediante graficas, tablas y diagramas de barras. El modelo grafico para obtener los resultados se realiza mediante un bloque discreto en Simulink. Finalmente, se determina que el modelo DFIG mejora las condiciones en una Micro-red y es la mejor opcion frente a otras configuraciones de generadores eolicos.

TL;DR: The performance of the both control scenarios in terms of power reference tracking and robustness against machine parameters inconstancy has been shown, analyzed and compared, which can afford a reference to the operators and engineers of a wind farm.
Abstract: Abstract—This paper appraises the performances of two control scenarios, for doubly fed induction generator (DFIG) operating in wind generation system (WGS), which are the direct decoupled control (DDC) and indirect decoupled control (IDC). Both control scenarios studied combines vector control and Maximum Power Point Tracking (MPPT) control theory so as to maximize the captured power through wind turbine. Modeling of DFIG based WGS and details of both control scenarios have been presented, a proportional integral controller is employed in the active and reactive power control loops for both control methods. The performance of the both control scenarios in terms of power reference tracking and robustness against machine parameters inconstancy has been shown, analyzed and compared, which can afford a reference to the operators and engineers of a wind farm. All simulations have been implemented via MATLAB/Simulink.

Abstract: A tendency to erect ever more wind turbines can be observed in order to reduce the environmental consequences of electric power generation. As a result of this, in the near future, wind turbines may start to influence the behavior of electric power systems by interacting with conventional generation and loads. Therefore, wind turbine models that can be integrated into power system simulation software are needed. In this contribution, a model that can be used to represent all types of variable speed wind turbines in power system dynamics simulations is presented. First, the modeling approach is commented upon and models of the subsystems of which a variable speed wind turbine consists are discussed. Then, some results obtained after incorporation of the model in PSS/E, a widely used power system dynamics simulation software package, are presented and compared with measurements.
