Abstract: The power control system structures for a doubly‐fed generator (DFIG) are proposed. The classical field oriented control and the feedback control with the multi‐scalar variables were considered. The generator is working in the AC grid connection mode. The rotor side of the generator is connected to the current source converter (CSC); the stator is directly related to the AC grid. The static feedback linearization using the multi‐scalar variables of DFIG is proposed to increase active and reactive power control accuracy. The proposed control structure allows to linearize the generator system, and decoupled between the control paths. The proposed approach can be called voltage control because one of the control variables is the voltage in the DC‐link of the CSC. The simulation and experimental investigations in the 2 kW DFIG system consider the AC grid voltage dips, confirming that the proposed control system remains stable. [ABSTRACT FROM AUTHOR]
