Wind turbine baldes equipped with air-jet vortex generators: full scale verificaiton of balde optimised for increased performance

摘要

In a pilot project,the blade set of a 150kW stall rgulated wind turbine was modified with air jet vortex generators and tested at full sscale.this was done primarily to incrasse the4 energy yield of the wind turbine by reducifng energy loss in the regin of the pwer curve 'knee',but also ot allow a degree of power regulation in high winds.The current project's aims are to modle the previous work numericlaly and os prouduce a low-cost tool fro opitmising a given blade.The numerical model will subserquently be verifie dby iwnd tuhnel tests and a full scale demonstration with a 600 kW machine.Both porjects are describe din this paper.
