Load measrueemnts on a pitch ocntrolled,free yaw hawt oeprating at omplex terrain

摘要

Fatigue load and performance mearurements carried out on a HMZ300 Windmaster,pitch controlled,free yaw wind turbine oeprating in windy complex terrain are analysed with a multivariate regression analyssi to clarify the mechanisms of fatigue loading in terms of the detemrinistic and stochastic wind characteirsitcs and the ncelle yaw error.The analyusis revealed tha tthe standard deviation of th longitudinal velocity component,and the distriugktion of turbulent kinetic energy in the lateral and verticla wind components re the main fatigue genrating wind parametes for the towere and blade laods; the contribution of yaw error has been found sigificant in the power regulation range.
