Jan 26, 2010· How to calculate power output of wind. By Editor | January 26, 2010. ... The following formula illustrates factors that are important to the performance of a wind turbine. Notice that the wind speed, V, has an exponent of 3 applied to it. This means that even a small increase in wind speed results in a large increase in power.
Planned Production Time. As described in the OEE Factors page, the OEE calculation begins with Planned Production Time.So first, exclude any Shift Time where there is no intention of running production (typically Breaks).. Formula: Shift Length − Breaks Example: 480 minutes − 60 minutes = 420 minutes Run Time. The next step is to calculate the amount of time that production was actually ...
