Multimegawatt wind turbine systems, often organized in a wind farm, are the backbone of power generation based on renewable energy systems. This article reviews the most adopted wind turbine systems, adopted generators, converter topologies, generator control and grid connection problems, as well as their availability in wind farms. At the time of the energy crisis, the role of MULTI Mega Watt WIND TURBINES and wind farms play an important role in its resolution. The importance of renewable energy resources is growing day by day. Electricity can be produced from wind energy by Multi MW wind turbines. Wind turbines can be built offshore or onshore. High wind potential of offshore wind farms.
The different conventional generators
• Dual fed induction generators (DFIG)
• Squirrel Cage Induction Generators (SCIG)
• Synchronous generators (SG)

Double-fed induction generators are widely used for variable speed generation. Reduced power converters have 30% rated power. The stator is connected directly to the network. The speed range is limited and sliding rings are required to connect the drive. A combined gearbox mechanism is required. Failure handling capability is poor.
The squirrel cage induction generators are rugged and mechanically stable. Rotor consist of metal bars, resistant to dirt and vibration. Two full-scale power converters are required. The fault current is limited by the network side converter. Variable speed operation can not be achieved by using small power converters. Can not be used in direct directed WECS. Synchronous generators are more efficient The synchronous generator is the direct drive PMSG. They have less loss of power. Noise reduction is achieved as the gearboxes are eliminated. For offshore applications, oil spills from gearboxes are eliminated. They are more reliable. Cost, weight and size is more than DFIGs.
