Study of Induction Generator and Inverter for Wind Energy Applications
نویسنده
چکیده
For low power wind energy or micro-hydel applications of the order of 1-10KW, the lowest cost can be achieved if the generator is a simple squirrel cage induction motor used as a self excited induction generator (SEIG). The induction generator output can be rectified to produce a DC Bus from which a single phase inverter can feed the power supply grid. A SEIG requires capacitors to be connected to the three terminals to provide reactive power as it is not directly connected to the power supply grid. The aim of the paper is to check the feasibility of wind power generation with a 2 KW squirrel cage induction motor used as a generator. A single phase current hysteresis controlled IGBT inverter is proposed to supply the mains utility power supply with the generated power. The complete system has been simulated.
