| Outline of Final Research Achievements |
The generator voltage of a cutting-edge wind turbine generation system (WTGS) is expected to increase from the conventional low-voltage level of 690 V to a medium-voltage level of 6.6 kV with a power level up to 10 MW without the
application of a parallel connection of multiple power units. This research project proposed a 10-MW WTGS consisting of a three-phase open-winding synchronous generator equipped with six lead terminals and three modular multilevel converters (MMCs) which are identical in terms of circuit configuration. The validity of the system has been confirmed by computer simulation using PSCAD software package along with experiment using a down-scaled system. Moreover, this research projects has proposed a new non-isolated dc-dc converter which can achieve reduction in size and weight of an inductor. The validity of the new dc-dc converter has been confirmed by a 150 V down-scaled system and computer simulation using PSCAD software package.
