“…The control strategies adopted in the induction motor power generation system mainly include rotor flux linkage orientation [18], stator flux linkage orientation [19], direct torque control [20] and slip frequency control [21]. Among them, the slip frequency control has achieved very good dynamic and static performance in a dual stator-winding induction power generating system operating in a constant power area [22,23]. Without flux linkage observation, torque estimation and complex coordinate transformation, this method has a better real-time performance for saving the current loop affecting the system dynamic performance.…”

Abstract:In order to broaden the limited utilization range of wind power and improve the charging and discharging control performance of the storage battery in traditional small wind power generation systems, a wind power system based on a vertical-axis off-grid induction generator is proposed in this paper. The induction generator not only can run in a wide wind speed range but can also assist the vertical-axis wind turbine to realize self-starting at low wind speed. Combined with the maximum power point tracking method, the slip frequency control strategy is employed to regulate the pulse width modulation (PWM) converter to control the output power of the proposed system when the wind speed and load change. The charge and discharge of the storage battery is realized by the segmented current-limiting control strategy by means of an electric power unloader device connected to the DC bus. All these implement a balanced and stable operation of the proposed power generation system. The experimental research on the 5.5 kW prototype system is developed, and the corresponding results verify the correctness and feasibility of the system design and control strategy. Some comparison experiments with a magnetic suspension permanent magnet synchronous generator (PMSG) demonstrate the application prospect of the proposed vertical-axis off-grid induction generator wind power system.

Dual stator winding induction generators (DSWIG) can provide controlled excitation and hence offer a brushless alternative to traditional synchronous machines or doubly fed induction machines (where a 2 nd supply is injected to the rotor through a converter-inverter systems). These generators are a potential candidate for extraction of power from renewable energy resources such as wind, micro-hydro etc. as these are very robust and require the least maintenance. Such systems are also suitable for on-grid/off-grid operation in a micro-grid. This paper deals with a model reference adaptive system based reactive power controller. The excitation winding of the DSWIG is fed from an inverter and controlled in synchronism with the power winding to achieve rotor flux orientation and direct reactive power control. Extensive simulations on SIMULINK validate the proposed method.

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.
