Abstract:
In the current work, we have given a simple parameter-based analytical approach for calculation of continuously variable transmission (CVT) optimal regulation curves in a small wind energy conversion (WEC) system. A CVT is placed between turbineâ€™s rotor and an induction generator directly connected to the power system, enabling better utilization of available wind power. We have developed methods to calculate the optimal CVT regulation curve in details and has been applied to the small WEC with rated power of 55 kW. Effects of generatorâ€™s winding resistance variation, caused by temperature change, have been studied further. During the testing  we found that there is no impact of the calculated curves on the normally expected changes of the windingâ€™s resistances.
