Determining the true performance of each wind farm turbine is extremely difficult if not impossible. Nowadays performance measurements in wind farms are limited to single turbines with free wind sectors, defined flat areas and using dedicated met masts. Although lidars have the potential to replace met masts they are limited to the same constraints. Hence the only wind measurement source available on each turbine is the nacelle anemometry, which provides neither meaningful nor trustworthy input for a performance measurement. Here the spinner anemometer technology iSpin can change the game and provide more transparency and insights in turbine performance. Due to its unique position and measurement principle in front of the rotor it is possible to overcome the limitations of conventional nacelle anemometry in two ways:
First of all it is possible to measure the main aspects which define the wind input. Secondly the iSpin measurements show high robustness for local flow conditions, different from those of e.g. a reference measurement on a prototype site. Based on the iSpin technology an approach is presented using these capabilities for performance monitoring and performance comparisons of wind farm turbines. Contrary to conventional nacelle anemometry iSpin allows the usage of 360° inflow data even in wake of other turbines or behind obstacles. This enables a holistic overview of the performance of individual turbines and the wind farm itself.
