“…To simplify our analysis, the influence of mutual leakage between two sets of stator windings is ignored, and only the fundamental component is taken into consideration. The excitation reactive current fed from the SEC to adjust Φ m is regarded as a current source [11].

This paper presents a grid-connected dual stator-winding induction generator (DWIG) wind power system suitable for wide wind speed ranges. The parallel connection via a unidirectional diode between dc buses of both stator-winding sides is employed in this DWIG system, which can output a high dc voltage over wide wind speed ranges. Grid-connected inverters (GCIs) do not require booster converters; hence, the efficiency of wind energy utilization increases, and the hardware topology and control strategy of GCIs are simplified. In view of the particularities of the parallel topology and the adopted generator control strategy, we propose a novel excitation-capacitor optimization solution to reduce the volume and weight of the static excitation controller. When this excitation-capacitor optimization is carried out, the maximum power tracking problem is also considered. All the problems are resolved with the combined control of the DWIG and GCI. Experimental results on the platform of a 37 kW/600 V prototype show that the proposed DWIG wind power system can output a constant dc voltage over wide rotor speed ranges for grid-connected operations and that the proposed excitation optimization scheme is effective.

Modern micro-grid needs to integrate all possible and economically attractive renewable energy resources. In many cases these generations are not smooth in nature and are situated in remote locations where regular maintenance is difficult. This paper proposes a brushless generation system using a dual stator winding induction generator (DSWIG). The power winding of the DSWIG is connected to the grid by rectifier-inverter system, whereas, the excitation winding is fed from an inverter. The generator is controlled in a way to enable terminal voltage regulation of the main winding by controlling the rotor flux through the excitation winding. Preliminary results show the capability of the system to regulate voltage and maintain constant frequency at the micro-grid. Simulations results show usefulness of such systems for micro-grid operation.

A new configuration for the self-excitation of the induction machine invented by Magnus Lindmark is presented. The power electronic converter using solid state switches is connected to the rotor while the stator is directly connected to the grid. Using appropriate control, the reactive power consumed by the motor can be generated in the rotor resulting in unity power factor operation. The rotor connected power electronic converter is also used for constant speed operation of the induction machine at variable torque.
