Wind turbine power performance testing

Power performance testing (PPT) is the independent measurement of wind speed at site along with the wind turbine generators (WTG) power output, to compare against the warranted power curve. Power curve measurements offer a

Key steps for wind turbine power performance testing

This is done by utilizing the blockage effect, which can sometimes be quantified by segregating data into two different categories: 1) when the wind comes from a direction that places the met tower upwind of the

Key steps for wind turbine power performance testing

Meteorological towers (met towers) configured with industry-standard anemometers to gather wind-speed measurements are the wind industry''s most widely accepted wind measurement methodology.

6 FAQs about [Wind power test tower]

Can a floating wind turbine be used for wind tunnel testing?

This work addresses this issue by designing a scale model of a floating wind turbine for wind tunnel testing, and proposes a dynamic aerodynamic thrust measurement method based on surface pressure measurements.

What is power performance testing?

Testing performance is essential to ensuring that turbine and plant performance meet expectations and contractual obligations. Put simply, power performance testing is measuring wind speed, measuring a turbine’s power output, then plotting the power versus wind speed and comparing that to the warranted power curve.

Should a met tower be closer to a turbine?

Placing a met tower closer to a wind turbine can exaggerate the 'blockage effect' on the power curve test. This method of scatter reduction is a trade-off, so the pros and cons must be weighed carefully.

How to verify the performance curves of a wind turbine?

To verify the performance curves of the turbine, a wide range of TSR needs to be adjusted. The rated wind speed of the prototype is 11.4 m/s with a rated speed of 12.1 rpm. The appropriate wind speed for the scaled ones is 6 m/s and 635 rpm. Therefore, a wide range of TSR is obtained by adjusting the speed and incoming flow around this point.

How to predict wind power generation?

In wind energy industry, due to the pronounced variability of wind, the prediction of wind power generation is normally carried out by means of statistical models, in conjunction with the properties of wind turbine (e.g. the power curve in Fig. 10 ).

What is a meteorological tower?

A meteorological tower (met tower) is a structure used in the wind industry to gather wind-speed measurements. It is configured with industry-standard anemometers. Meteorological towers have been used for decades for wind energy measurement applications to technically support project financings.
