title = "Overview of and trends in wind turbine generator systems",
abstract = "This paper gives an overview of wind turbine generator systems and describes some trends. Around 1998, many wind turbine manufacturers changed from constant speed systems to variable speed with doubly-fed induction generators. Since around 2005, they have come with a number of alternative generators systems, mainly to comply with grid requirements as grid-fault ride-through. Most alternatives have brushless generators and full converters. One of them is the direct-drive system. If the availability of permanent magnet materials can be guaranteed, permanent-magnet generators are considered as the most suitable direct-drive generators. The increasing importance of offshore wind energy results in an increasing attention for reliability and availability.",
