Variable-speed wind turbines are equipped with a pitch-change mechanism to adjust the blade pitch angle and obtain a better power coefficient profile. The basic principle behind their operation is electromagnetic induction. Beyond rated wind speed, the desired power is flat at rated power. Since the model is intended to study the dynamic response of wind turbines to grid events, the assumption is usually made that the wind speed stays constant during the grid event. The rectifier, buck/boost converter and inverter are modeled explicitly using diode and IGBT models supplied with PSCAD/EMTDC. powered by wind-turbine.com. It should be noted that the pitch angle values are inverted (negative rather than positive) due to the CP lookup table characteristics; -8 degrees here thus corresponds to 8 degrees in the real world. The real power error drives the Iq signal, while reactive power error drives the Id signal. Reactive power rises initially but recovers to the original value.
