Inertial control method for double-fed wind turbine

The invention discloses an inertial control method for a double-fed wind turbine. The active power output reference value of the double-fed wind turbine is controlled by a maximum power tracking algorithm; if it is detected through system frequency that the system frequency is normal, the active pow...

Beschreibung
Zusammenfassung:	The invention discloses an inertial control method for a double-fed wind turbine. The active power output reference value of the double-fed wind turbine is controlled by a maximum power tracking algorithm; if it is detected through system frequency that the system frequency is normal, the active power output reference value of the double-fed wind turbine is controlled by the maximum power trackingalgorithm, otherwise the active power output reference value of the double-fed wind turbine is controlled by the linear active power output of the rotation speed of the rotor of the double-fed wind turbine; if it is detected through the rotation speed of the rotor of the double-fed wind turbine that rotation speed change rate is less than or equal to the rotation speed change rate threshold valueof the rotor of the double-fed wind turbine, the active power output reference value of the double-fed wind turbine is controlled by the active power output of the rotation speed of the rotor of thedouble-fed wind turbine, ot
