Electronic control by the load for asynchronous turbogenerators,driven by multiple sources of energy

摘要

This paper shows a technique of electronic control by the load formicropower plants which adapts itself to several alternative sources ofenergy. As a part of this study, it is shown how each of these primarysources (water, wind, diesel and solar) may be run at their ownfrequencies to feed a common DC busbar. The electrical variablesobserved and of more interest are the DC busbar voltage, current andpower. Also, the generator's power and rotation presented some practicalinterest as the power plant efficiency and capabilities are closelyrelated to them. Some difficulties were detected for further improvingvoltage regulation as it does not change much from the inductiongenerator's own characteristics
