The Study of Individual Pitch Control on Reducing The Load Fluctuation of Tower Shadow

Abstract:

Article Preview

Load fluctuation of wind turbine under tower shadow was researched,introducing individual pitch control. First,establish the linear time-varying model of the rotor,make it into the linear time invariant model through Coleman transformation. Then,based on this model,achieving the design of individual pitch system with PID controller. Comparing the loads of wind turbine under tower shadow between individual pitch control and collective pitch control and analysing the fatigue damage of wind turbine through rainflow cycle counting.The result shows that load fluctuation of wind turbine using the individual pitch control under tower shadow has better effect and reduces the effect of tower shadow,extend the working life of wind turbine.
