Optimization Of Technologies And Equipment From Process Industries

Abstract:

Because a good match can be obtained to the short-term distribution of rain flow ranges given the first three moments and a fixed data truncation, it is sufficient to know the moments over all the operating conditions in order to fully define the turbine fatigue loading. Regression of the moments over ten-minute average wind speed and turbulence intensity can achieve the desired result and assist in understanding the loading dependence on and sensitivity to both turbulence and wind speed. Results from a regression analysis can also provide information on the uncertainty of the loads.
