DEVELOPMENT OF WIND TURBINE SYSTEMS WITH PAR.VLLEL CONNECTIONS OF DIFFERENT TYPES GENERATORS

摘要

The work paper explores the possibility of wind power conversion systems developing by parallel coupling of main different types power AC generators such as induction generator and permanent magnet synchronous one in isolated grid. Due to different electromagnetic processes underlying operation, the currents per phase developed present different differences phase, and therefore is usually obtain a low output power. It was found that optimizing the output current can be made by choosing appropriate an optimal combination of pole pairs for different generators.
