摘要

Micrositing of wind turbines in complex terrain isrntricky game, and many of the current sitingrnmethods and tools, while useful and improving,rnremain inadequate to the task in extreme terrain.rnAs a consequence, there are numerous windrnturbine installations that are buffeted by damagingrnturbulence or are faced with suboptimal windrnenergy performance.rnFlow separation at mountain peaks and the leadingrnedge of cliffs and escarpments is a primary culpritrnthat can lead to poor performance or damagingrnturbulence. Many practitioners poorly understandrnthese phenomena, but the blame can also be laid atrnthe feet of assessment tools that are not suitablernfor complex, separating flow conditions.rnTerrain geometries can do strange things to flowrnpatterns. Geophysical phenomena such as thermalrnstratification and Earth’s rotation can add to therncomplexity. Thus, mountain peaks, terrain saddlernpoints, steep escarpments, and other intricaternterrain shapes can play havoc with flowrnconditions.rnA combined approach utilizing wind tunnelrntesting, a “refined” mesoscale numerical model,rnand “effective” field testing is shown to be arnviable tool for the accurate micrositing of windrnturbines in these complex terrain settings.
