Electromagnet Compatibility Study in a Renewable Energy Induction Generator

Resumen

This paper shows a study of the interferences introduced in the power network produced by the asynchronous generators. It is aimed at presenting a comparison of the behaviour of the generators used in renewable energy plants; namely asynchronous generators in their two modalities: squirrel cage and wound rotor. The advantage of the squirrel cage relies on its great simplicity, but the improvement in regulation and electrical power quality of wound rotor generators has also been improved. The latter provide stator and rotor regulation, that is to say, a doubly-fed generator. These results have been obtained from measurements taken in the ETAP (Station of Drinking Water Treatment) of Logrono for squirrel cage induction generators, and in the Wind Farm of Yerga (La Rioja) for wound rotor generators. © 2001 IEEE.
