Unlocking complex wind sites  

Deutsche WindGuard's new ZX Complex Flow Solver (ZX CFS) is the result of a joint development with ZephyScience, supported by lidar OEM ZX Lidars. Fully based on computational fluid dynamics (CFD), ZX CFS identifies, quantifies, and resolves the relative differences between lidar and cup anemometer measurements witnessed in complex terrain. The Complex Flow Solver algorithm developed by Deutsche WindGuard is optimized for ZX Lidars' wind field reconstruction. Incorporating results from a high-resolution CFD model, it derives a set of conversion factors. Applied to the volume-based wind data from Continuous Wave Lidar ZX 300, which samples 50 measurements points per second, these conversion factors produce single point measurements equivalent to those of a cup anemometer installed at the same location. ZX CFS even provides guidance on where to install the lidar initially to achieve the lowest possible uncertainties. Cloud computing delivers fast, transparent, and accurate results.
