FIELD TEST AND DYNAMIC SIMULATION OF SMALL WIND TURBINE PERFORMANCE UNDER HIGHLY TURBULENT CONDITION

抄録

Small wind turbines often operate under highly turbulent conditions. A performance test and aero structural simulation was done on the power output of a 135W SWT in a turbulent environment. The results showed an increase in average power output with increasing turbulence intensity(TI), this was more pronounced at TI values above 25%. The increase in power was more pronounced at higher wind speeds (exceed 7m/s). A FAST model was used for simulation. There was good correlation between the FAST model and field test ,the error was never more than 20% for lower wind speeds and 8% for higher wind speeds.
