In this paper, the dynamic performance and control of a doubly fed generator is investigated. It is shown experimentally that a reactive current regulator can be used to control the machine excitation level. The study initially assumes an externally controlled field frequency, so that the machine is in the controlled speed mode. Linearized analysis is used to show that larger generators may be subject to dynamic instabilities at high slip operation. It is shown that feedback of shaft speed along with the stator or rotor current vector can be used to provide stable operation.
