With the development of modern wind energy generation, higher requirements to the grid in case of a failure were raised. In order to faciliate the recovery of power, while voltage dips in a certain range, protecting the rotor side converter and providing reactive power to the grid are both needed according to the requirements. This paper takes DFIG for example, in order to protect the rotor side converter,...
Regulatory standards for grid interconnection require wind generators to ride through disturbances such as faults and support the grid during such events. Conventional accommodations for providing voltage sag ride-through for doubly fed induction generator (DFIG) wind turbines result in compromised control of the turbine shaft and grid current during unbalanced faults. This paper presents the analysis...
Traditionally voltage source inverter (VSI) and current source inverter (CSI) fed induction motor drives have a limited output voltage range. Conventional VSI and CSI support only current buck DC-AC power conversion and need a relatively complex modulator. The limitations of VSI and CSI are overcome by Z-source inverter. The Z-source inverter system employs a unique LC network in the DC link and a...
