This paper presents implementation of Feedback Linearization based control (FBLC) for the smooth connection of the doubly fed induction generator to the power grid and for the power control of the grid connected doubly fed induction generator. The induced stator voltage vector of the DFIG is synchronized with the grid voltage irrespective of the accuracy of signal from position encoder. Computer simulation...
A systematic methodology for smooth connection of wind-turbine-driven doubly fed induction generators (DFIGs) to the grid is presented. Synchronization of the voltage induced in the DFIG open stator to that of the grid, which needs to be accomplished prior to connection, is thoroughly examined. A particular grid-voltage-oriented rotor control scheme is considered for this purpose. Generic tuning equations...
Doubly-fed induction generator (DFIG) is the most common type of generators for wind power generation, because of their high energy yield and the possibility of generating power at variable speeds. For most papers in literature, only the synchronization and power generation of DFIGs, but not the transition between them, are discussed. This paper presents a method to control the transition of DFIGs...
A grid connected power generation systems based on the superior controllers of an active and reactive power are useless during a grid failures like grid short-circuit or line braking. Therefore the change of operation mode from grid connection to stand alone allows for uninterruptible supply of a selected part of grid connected load. However, in the stand alone operation mode the superior controllers...
