Performance Transparency Project (PTP)

Wind turbine performance evaluation in all terrains

The iSpin Performance Transparency Project (PTP) is one of the largest and most systematic demonstration projects for a wind measurement system so far. Around 90 iSpin systems will be installed during 2017 and 2018 on wind turbines in 9 different wind farms. 3 different turbine types – each of them installed at wind farms in 3 different terrain classes like flat, semi-complex, complex or offshore – will be evaluated by independent 3rd party consultants. At each of the wind farms one met mast or lidar system will be used for a time period of at least 12 months. This enables to evaluate the iSpin Spinner Transfer Function (STF) stability and the power performance measurement capabilities over time.
