Measurement and Simulation of the Flow Field around a Triangular Lattice Meteorological Mast
Measurement and Simulation of the Flow Field around a Triangular Lattice Meteorological Mast
摘要
The international standard IEC 61400-12-1 Wind turbines--Part 12-1: Power performance measurements of electricity producing wind turbines" aims to provide a uniform methodology that will ensure consistency, accuracy and reproducibility in the measurement and analysis of power performance by wind turbines. Annex G of this standard provides a methodology for the appropriate arrangement of instruments on the meteorological mast to ensure accurate measurement. For cup anemometers it provides recommendations about their location relative to the mast so that the effect of mast and boom interference on their output may be minimised. These recommendations are given for both tubular masts and lattice masts. This paper compares the flow distortion predicted by the IEC standard and the results of a 3D CFD (computational fluid dynamics) simulation of a triangular lattice mast. Based on the results of wind tunnel and CFD simulation it was found that the flow distortion surrounding the lattice mast was overpredicted by the method suggested in appendix G oflEC61400-12-1. Using the CFD data it was possible to determine, for a range of flow directions and mast heights, the distance from the mast that anemometers would need to be in order to be outside the flow distortion field.
