Wind turbine performance. An actual wind turbine is only operated in a range between a minimum velocity, called the cut-in velocity, and a maximum velocity, called the cut-out velocity. The power coefficient, cp, is defined as the fraction of the wind power that is actually captured.

A sample of the mast bending, the rotor speed, and the wind speed is shown in Figure 5. Figure 5. Mast bending, wind speeds, and rotor speed, record 20190319-1312. There is a dominant 1P component in the mast bending signals but the amplitude of this component varies due to fluctuating wind speed and rpm values.

Expected energy output per year can be reliably calculated when the wind turbine's capacity factor at a given average annual wind speed is known. The capacity factor is simply the wind turbine's actual energy output for the year divided by the energy output if the machine operated at its rated power output for the entire year.

Wind turbine type. Horizontal axis wind turbine (HAWT) with 3 blade upwind rotor – the “Danish concept”: Load cases. We will consider two load cases: 1) Normal operation – continuous loading. Aerodynamic, centrifugal and self-weight loading. Deflection - blades must not hit tower. Cyclic stresses – fatigue. 2) Extreme wind loading ...

After a lengthy calculation period, you should now have a wind resource grid. The next step is to create a new layer that will hold the locations of proposed wind turbines. Right-click in the table of context and click new layer in the dialog that appears. Then select Turbine Layout to create the layer.

An electrical utility must have backup generation equal to the wind turbine maximum output connected and idling at low load (and low efficiency) - ready to load at all times wind generators are on line, as they can (and experience shows do) vary from low load to full load, and back to low load over short time periods.
