These massive structures, also referred to as offshore wind turbine units, symbolize China's position as a global leader in the renewable energy sector. With a focus on developing five major offshore wind power bases, the offshore wind farm in east China's coastal province of Shandong is whe...
Figure 1 shows the variation of wind turbine power with rotational speed under several wind speeds, indicating that the wind turbine output power is affected by wind speed and its rotational speed22,57. Figure 1 The wind turbine power with rotational speed under various wind speeds. Full size ...
Although the calculation of wind power illustrates important features about wind turbines, the best measure of wind turbine performance is annual energy output. The difference between power and energy is that power (kilowatts [kW]) is the rate at which electricity is consumed, while energy (kilowa...
