“…The rotational cycle is closed by going t o the upper anemometer (t = 4At) and the process repeats again. The time lag between the t w o samplings at hub height crudely accounts for the wind's horizontal shear (Connell et al 1988). 161).…”

This paper presents a technique of estimating blade fatigue damage at potential wind turbine sites. The cornerstone of this technique is a simple model for the blade’s root flap bending moment. The model requires as input a simple set of wind measurements that may be obtained as part of a routine site characterization study. By using the model to simulate a time series of the root flap bending moment, fatigue damage rates may be estimated at the potential wind energy sites. The model is evaluated by comparing these estimates with damage estimates derived from actual bending moment data; the agreement between the two is good. Data from two different turbine types were used for the evaluation. For each type the model was tested at only one site because data from other sites were not available. To more firmly establish the universality of the model, further evaluation is necessary using the model applied to the same turbine located at different sites.

“…Several other studies (Connell and George 1983b;Connell et al 1988;Connell, Morris and Hinchee 1987) have resulted from the development and testing of a model for simulating the rotationally measured wind velocity using conventional turbulence measurements at a few heights on a single tower. The model, STRS-2, was used to make the first estimates of the turbulent wind characteristics, using wind measurements that would be experienced by largeto-very-large turbines.…”

“…The error in the STRS-2 method may be estimated by looking at the correction factors (the inverse of the error) shown in Figure 4.5. A more complete discussion of error is given in the PNL report by Connell et al (1988).…”

The PNL single-tower measurement model of rotationally sampled turbulent wind, with user's guide for STRS2PC

Abstract: This program models the turbulent wind encountered by a point on a rotating wind turbine blade by transforming a time series of the wind speed measured by anemometers on either a single tower or a multi-tower array from eulerian to rotational coordinates.
