Contribution to the development of wind energy systems using static power electronic converters

摘要

A wind energy system, using a squirrel cage induction machine and a static power electronic conversion equipment, incorporating a novel and economical pulse frequency modulated three phase auxiliary impulse commutated inverter, is described. A complete description of the proposed power as well as control schemes is given, with special reference to its possible application in variable speed wind power conversion scheme. Experimental results obtained on ?? laboratory breadboard of the power electronic conversion equipment for a 2 KVA,208 V, 60 Hz, 3 phase squirrel cage, inverter fed induction machine in self excited mode of operation with a 3 to 1 speed range, are reported.
