Abstract

This report describes a three-bladed, upwind, variable-speed, variable blade-pitch-to-feather-controlled multimegawatt wind turbine model developed by NREL to support concept studies aimed at assessing offshore wind technology.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • For modern multi-megawatt pitch-regulated wind turbines, the rotational speed is constant when the mean wind speed is between the rated wind speed and the cut-out wind speed due to the functioning of the pitch controller.

    “For modern multi-megawatt pitch-regulated wind turbines, the rotational speed is constant (slightly oscillating around this mean value due to turbulence) when the mean wind speed is between the rated wind speed and the cut-out wind speed due to the functioning of the pitch controller [57].”
  • P_acc,min was determined for wind turbines of three different sizes, Aventa AV-7, DTU 10MW, and NREL 5 MW, in the range between 5 Pa and 40 Pa with a P_dyn,avg above 1 kPa.

    “P acc,min was determined for wind turbines of three different sizes, Aventa AV-7 turbine [19], DTU 10MW wind turbine [20], NREL 5 MW [21], in the range between 5 P a and 40 P a with a P dyn,avg above 1 kPa.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
