9.0 Wind Turbine Operation | 79 |
4.Reset the turbine test switch to OFF.
5.Observe the wind turbine; the parking brake should engage and the rotor should stop.
WARNING
THIS TEST SHOULD ONLY BE CARRIED OUT IN LOW WIND
CONDITIONS.
9.3.3Rotor Jog Test
1.Set the turbine test switch to TEST.
2.Turn the rotor jog switch to ON, connecting the wind turbine to the grid.
3.The rotor should turn counterclockwise when viewed looking upwind.
4.If the sense of the rotation is not correct shut down the system and swap any two of the 480 V leads to the generator to reverse the phase rotation.
5.Reset the rotor jog switch to OFF.
6.Reset the turbine test switch to OFF.
9.3.4Dynamic Brake Test
1.Set the turbine test switch to TEST.
2.Set the dynamic brake switch to ON, disabling the parking brake and tip brakes.
3.Set the rotor jog switch to ON, connecting the wind turbine to the grid.
4.Allow several seconds for the wind turbine to come up to speed (64 rpm).
5.Turn the rotor jog switch to OFF.
6.Observe the wind turbine for any noticeable speed loss.
7.After 10 seconds maximum, switch the dynamic brake switch to OFF to apply the tip brakes and the parking brake.
9.3.5Anemometer Signal Test
1.With some measurable amount of wind (> 4.5 m/s (10 mph)), determine the voltage (DC) across the terminals 5
2.The voltage should read between 0 and 5 VDC corresponding to a wind speed of 0 - 44.7 m/s (0 - 100 mph). Both anemometers should read approximately the same values. See Appendix H for voltage to wind speed conversion.
