Weng

What is Weng?

Weng is the industry standard PC software for calculating wind conditions, relevant to fatigue loads, extreme loads and location of wind turbines and wind farms.  Weng is used in locations located on all types of terrain around the world and includes models and tools for every step of the process, from analyzing wind data to calculating the wind conditions of a wind farm. Nearly 1000 WAsP engineering licenses have been sold in about 50 countries.

Typical WAsP engineering applications:

Calculation of wind conditions for IEC site assessment, e.g., shear, environmental turbulence, extreme wind, and wind flow slope for individual wind turbines in a wind farm.

Location of wind turbines in a wind farm

Weng contains physical models to describe wind flow in different terrains and near protective obstacles. For horizontal and vertical extrapolation, Weng uses the built-in LINCOM model, which will work properly on flat to moderately complex terrain. Weng  also contains three extreme wind models, as well as Mann's turbulence model.

The data used by Weng comes from different sources. Wind data can come from wind measurements on an on-site weather mast or from meso-scale modeling results. The topographic description is derived directly from space shuttle elevation data or other datasets, while the description of land cover and nearby shelter obstacles can be extracted from topographic maps, databases, or satellite imagery (Google Earth).

Weng comes complete with free utility tools for wind data analysis and digital map construction and editing, as well as IEC 61400-1 site assessment and IEC 61400-12-1 power performance measurements.
