Modeling and Control Design for Wind Energy Power Conversion Scheme Using Self-Excited Induction Generator

This paper deals with dynamic modeling of self-excited induction generator connected to a supply system through a de link (converter-line commutated inverter) and digital control design for regulating the power transfer through the link. Using different sampling rates for the converter and inverter control loops, the proposed design ensures reduced reactive power burden on the induction generator. Results of implementation on a laboratory system are given.
