Abstract: The accurate estimation of rotor angle is an important prerequisite for realizing speed sensorless highperformance vector control of permanent magnet synchronous wind generator. In the speed sensorless control ofpermanent magnet synchronous wind generator based on disturbance observer，the traditional angle...

Abstract: Doubly-fed wind turbine is easy to produce sub-synchronous oscillation in series compensation grid.Using virtual synchronous control structure to improve inertia and damping for grid may also lead to subsynchronous oscillation risk. In view of the causes of sub-synchronous oscillation，firstly，the double-fe...

Abstract: With the continuous improvement of the penetration rate of wind turbines，in order to suppress thevoltage/frequency fluctuations of the doubly-fed induction generators（DFIGs）after grid-connected due to their own active power output fluctuations，aDFIGinertia support and primary frequencymodulation control ba...

Abstract: At present the mainstream of doubly-fed induction generators（DFIG）control mode is the currentsource type vector control mode，which is lack of independent of frequency and voltage support ability，but the voltage source type virtual synchronous machine control method can solve the shortcomings. In order to m...
