Wind speed (m/s)
Figure 13: A sample of track test, wind speed vs. power.
If the natural wind does not affect seriously, a series of steady performance
tests and structural tests including extreme conditions can be conducted. Highest
attentions shall be given for personal safety and structural safety.
Another valuable task is development of control strategy, which relates power
control, speed control, load regulation, break adjustment and yaw control.
Figure 13 is a sample of track test data of a Micro WT of 1.8 m rotor diameter.
Power output data are shown for two values of volt of battery load. By conducting
parametric tests, optimal control parameters can be found.
9.2.3 Field test
Final evaluation and validation of a SWT's power performance must be
determined by fi eld tests. It is because actual energy products from a WT are
obtained under free wind fl ow varying with time both in speed and in direction.
