Investigation of oad Reduction for a Variable Speed, Variable Pitch, And Variable Coning Wind Turbine

摘要

A two balded, variable speed and variable pitch wind turbine was modeled using ADAMS~direct R to evalaute loads reduction abilities of a variable coning configuration as compared to a teetered rotor, and also to evaluate control methods. The basic dynamic behavior of the variable coning turbien was investigated and compared to the teetered rotor under constant wind conditions as well as turbulent wind conditions. Results indicate the variable coning rotor has larger flap oscillation amplitudes and much lower root flap bending moments than the teetered rotor.
