Wind turbine angular velocity
Description
The formula for the calculation of the angular velocity of a wind turbine rotor. The definition is according to the IEC 61400-2.
If a disc is rotating at 60 rpm is said to be rotating at either 2π rad/s or 1 Hz, where the former measures the angular velocity and latter reflects the number of revolutions per second.
Variables
| ωn | Angular velocity (dimensionless) |
| π | pi |
| n | rotor speed in rounds per minute (dimensionless) |
