Abstract
Dual stator winding induction generator, being brush-less and magnet-less, has been found to be suitable for remotely located wind-electrical systems where maintenance becomes a key issue. Since this generator has a squirrel cage rotor and two distributed stator windings, manufacturing process is simple and system becomes rugged. Both the windings may contribute active and reactive power when operated with suitable controller and power-electronic interface. In this configuration, the main winding is connected to a diode-bridge rectifier. The other uses a controlled inverter. It is well known that reactive power consumption of induction generators rises with increase in load. A combination of series and shunt capacitors can be utilised to mitigate the above mentioned issues. Two possible configurations have been investigated through simulation studies on MATLAB/Simulink and a comparative assessment among the two has been carried out. Experimental investigation has been conducted on a dSPACE 1103 based prototype and a sample result has been presented.
