The variable speed wind turbine with stator controlled cage induction generator (SCCIG) is today widely
used concept. This paper presents a control system of the SCCIG wind turbine with focus on the control strategies and
on active power command value achievement. The present control method is designed for super-synchronous, subsynchronous
and synchronous working modes. In order to investigate the dynamic responses during step load of
SCCIG connected to the electric grid, a model has been developed. This model includes the mechanical drive train, the
induction generator as well as the control parts.
