This paper presents analysis and control techniques for a doubly-fed induction generator (DFIG) used in wind energy systems under unbalanced grid conditions. The rotor currents and electromagnetic torque of the DFIG under unbalanced conditions are first analyzed. Negative sequence circuit models are investigated. Control strategies implementing negative(More)
We present an FPGA-based design approach that will allow motor control and on-board condition monitoring to be achieved in parallel using the same set of physical variables. The key idea lies in exploiting the parallelism of FPGAs to achieve the joint objectives of control and monitoring using common physical variables, namely motor phase currents. For(More)
