Description
Summary:The doubly fed induction generator (DFIG) is the most used technology when it comes to the production of the electric energy for wind power generation. It has the advantage to insure a variable speed operation that will maximize the power extracted from the wind, increase the energy efficiency, reduce the torque oscillations and to generate an electric power with better quality. When we talk about microgrids which are a localized grouping of renewable electricity sources and loads, we should mention two cases of operation: the connected mode and the islanded mode. In this paper, we will focus on the first case (the connected mode). We propose an indirect decoupled control of the active and reactive power for the DFIG when the extracted power from the wind is stable and around 1.5MW, we also propose the control diagrams applied to the rectifier and the inverter with their respective models, in order to guarantee a good energy transmission. Simulation results are obtained for a power around 1.5 MW.
