Basic Principles  

Wind direction measurement accuracy is≈♥ε a critical factor affecting wind tu≥♣®rbine production efficienc​↓♥♠y. When installing wi •♠←nd speed/direction sensors on ‍‍turbines, the wind vane axis mus¶γ≠t coincide with or be paral™€≠lel to the turbine's ce‍>nterline according to th♠₽ e installation posit₽$ion. As shown in Figure 1, A1 •©∏and A2 represent wind vane axes para♥ llel to the nacelle centerline. Be¶☆£tter alignment between t♠©™he wind vane axis and the ∏♠∏nacelle centerline impr€↓®'oves the turbine’s accur ®acy in facing the primary wind d‌‍irection, thereby in&≈creasing production efπ✘‌ficiency.

When the alignment tool’s poinΩ§÷ter aligns with the sensor’σ䮀s "N" direction, the laφ$ser crosshair moves strictly along the ≤λ‍wind vane axis due to the hinge’s♣€ bending angle. Thus, aligning the l'§aser’s vertical line with×α¥ the centerline (or its par¥↑&♠allel) at the installation p≠≠∏÷oint ensures parallelism between λφ≤ the wind vane axis an↓♥±αd the centerline.  

Alignment Tool Usage Steps‌λ and Methods  

1. Determine Turbine Centerline &€β'amp; Parallel Line Through Sensor Posit×∑¥ion  

Identify the turbine’s centerliΩ ±ne or a parallel reference line on th±§‌e nacelle.  

Based on the sensor’s installatio¥↓©n point, mark a line passing thro§•♠₩ugh it that coincides with or runs par‍™®σallel to the centerline. Label∑× this position for subsequσ€↕™ent laser crosshair alignment. &nb₽®♣sp;

2. Finalize Sensor Orientation Usi€β‌ng Alignment Tool  

Install the sensor and pre-tighten the clamp  ×without securing it $ε≥☆fully. Orient the &qu×£←≤ot;N" direction towar∞<γd the rotor hub or tail (varies by ×∞™↑turbine model) per main controller ≤​‌requirements. Attach the tool above t→✘↔he sensor mast’s cable o↑✘ utlet (Figure 2). Align the tool’s po‍‍γinter with "N"σ λ÷: If "N" faces thδ★✘e tail: Align distal poin₹&↔terwith "N" (Figure 3). I ¶>✘f "N" faces the hu¥∏®Ωb: Align proximal pointer with "N" (Figure •≥4). Activate the laser an dsimultaneously rotate the sensor mast and alignment tool. Tighten the clamp** once the laser crλ☆★ osshair aligns with the mark from Ste©↕'p 1. The wind vane axi$∞'✘s now runs parallel to t≤ε he centerline.
