Variable speed wind turbine – Wikipedia
Original models of wind turbines were fixed speed turbines; that is, the rotor speed was a constant for all wind speeds. The tip-speed ratio for a wind For this, power converters are employed, which results in the de-coupling of the wind turbine from the transmission system.
What is a Wind Turbine and How Do Wind Turbines Produce Electricity?
Wind turbines are a great way to provide a source of clean energy for your home or business. Wind turbines are the evolution of the classic windmills that it and the gearbox or transmission increases that rotational speed for the generator
Direct drive turbine needs no gearbox
Most utility-sized wind turbines use a costly speed increaser to drive a generator. Netherlands-based Emergya Wind Technologies (EWT) however, builds wind turbines based on a direct-drive (gearbox free) design. The company says its turbine

Wind turbine: Apparatus used to convert the kinetic energy of wind into electricity. Wind turbines come in several sizes, with small-scale models used of distance of transmission, as well as availability (that is, how reliably the turbine will produce power when the wind is blowing)
efficiency in wind power transfer when interface a single-turbine
This suggests that the variable speed gearbox can be eliminated from the wind powertrains if multiple turbines are connected to the central generation unit. Conventional variable speed hydraulic drives exhibit the ruggedness, weight and controllability required for large wind turbines;
