درباره کنترل توان غیرفعال یک ماشین القایی دوسو تغذیه

In this paper the stator-side power regulation control problem of DFIM is approached. It is shown how a passivity-based controller can deal with this problem establishing a viable solution from both a dynamic performance perspective and a practical implementation point of view. The evaluation of the presented scheme is carried out by considering typical operation conditions, namely: active power generation with demanded or delivered reactive power. Special interest is given to the rigorous establishment of the stability properties of the closed-loop system, which allows for achieving remarkable dynamic responses, in terms of convergence rates as well as the region of attraction of the equilibrium point defined by a given operation regime. From a practical viewpoint, the usefulness of the scheme is concluded by realizing that the requirements imposed concerning the structural features of both the generator by itself and the power converter required for its operation, can be fulfilled by commercially available off-the-shelf devices.
