Wind-Turbine Asynchronous Generator in Isolated Network
The HPNSWD system presented in this example uses a 480 V, 300 kVA synchronous machine, a wind turbine driving a 480 V, 275 kVA induction generator, a 50 kW customer load and a variable secondary load (0 to 446.25 kW). At low wind speeds both the induction generator and the diesel-driven synchronous generator are required to feed the load.
Gas-powered motors on wind turbines?
For example, Colorado-based Hybrid Turbines Inc. is selling wind farms systems that marry a natural gas-based generator to a wind turbine. "Even if natural gas is used, the electricity produced…is twice as environmentally clean as burning coal," reports the company. Better yet, if a user can power them with plant-derived biofuels, they ...

Microgrid systems, such as solar photovoltaic (PV) and wind turbine (WT), integrated with diesel generator can provide adequate energy to supply increased demands and are economically feasible for current and future use considering depletion of conventional sources.
Frequency control of a wind-diesel system based on hybrid …
From Fig. 2, it can be seen that the diesel generator model consists of a governor and turbine.The adaptive SM LFC control output (u_{i} (t)) is designed for the governor of the diesel generator to regulate its output power. The controller can generate control signal 1 and control signal 2 by the ACE of different areas, which are then fed to …
Parallel Operation of Wind Turbine, Fuel Cell, and Diesel …
The fuel cell must operate at higher output power when the wind turbine generation is low. The fuel cell operated at about 60 kW in the lower wind speed region (t > 28 s). V. CONCLUSION This paper investigates the parallel operation of a wind turbine, a diesel generator, and a fuel cell array.

Design of generators for offshore wind turbines
In wind turbines, the generator is almost always placed in a nacelle on top of the wind turbine tower. Obtaining the required amount of power for driving the generator requires large wind turbine rotor blades. Due to this large blade requirement, wind turbine generators are usually located on towers that can be more than 100 m above sea level ...
