What is the design process of a wind turbine?

Design process The design process involves an initial site selection followed by an assessment of external conditions, selection of wind turbine size, subsurface investigation, assessment of geo-hazards, foundation and support structure selection, developing design load cases, and performing geotechnical and structural analyses.

What is the design process for an offshore wind turbine?

Design Process for a typical offshore wind turbine (Malhotra, 2007c) turbines are generally mass produced and available in four predefined classes based on wind speed. Consequently, the designer simply selects one of the predefined turbine classes that may apply to the wind farm site.

What is the capacity of a wind turbine?

Until around 1980, most wind turbines had a capacity of less than 100 kW. Small wind turbines generally require a higher capital cost per kW and have a lower eficiency (load factor) compared to big wind farms.

How to choose a wind turbine support structure?

Because the dynamic response of a typical wind turbine depends on the stiffness of the support structure, which in turn is inversely proportional to its free standing height (or water depth) to the third power, one can use the water depth as a main factor for selecting the support structure in initial design.

What factors affect the output power of a wind turbine?

The main factors of the output power are the wind speed and the length of the blades. The size of wind turbines has continued to increase, and the average capacity of new grid-connected onshore turbines rose from 0.05 megawatts (MW) in 1985 (EWEA, 2011) to 2.0 MW in 2014 (Broehl, Labastida and Hamilton, 2015).

How much deflection should a wind turbine tower have?

A wind turbine manufacturer requires that the tower does not exceed 30” of deflection during ultimate loads. The designer finds that by reducing the section size to a point where stresses fall just below the specified limits, deflection at the tower top is 34”.
