The IEC 61400-12-2 standard was used for the calculations. The SCADA system provided the data from the nacelle anemometer readings. The power curve and power coefficient curve were obtained from the data before and after the RBE installation. The graphics show the power and power coefficient curves for the two timeframes. The number of data points and the power and power coefficient values are listed for each timeframe.
