摘要：Among several types, variable speed-based wind turbine generator (WTG) is the most popular
type installed worldwide. This type of WTG is able to extract 5% more energy from wind speed compared
to the fixed speed WTG. There are two kinds of variable speed based WTG; Doubly Fed Induction
Generator (DFIG) and Full Converter Wind Energy Conversion System (FCWECS). DFIG and FCWECS
are placed at the first and second topWTG installation worldwide since 2004. However, both of them are
very sensitive to the grid dip fault and may violate the allowable margins identified by various international
Fault Ride Through (FRT) codes. This paper aims to investigate the responses of DFIG and FCWECS
during certain level of grid dips and compare their performanceunder such event. Results show some
differences of the performance of DFIG and FCWECS during voltage sag event, however the voltage
profile at the point of common coupling is much better in case of DFIG. Results also recommend that DFIG
can be effective when connected to weak grids whilst FCWECS is preferably to be connected to
strong grids.
