Abstract

a DFIG high voltage ride-through method with the consideration for the safe operation voltage of the generator unit is proposed in the article. Based on the dynamic reactive support capability of DFIG, during grid voltage swell, the reactive powers outputted by the grid-side converter and the generator stator are concertedly controlled so as to keep the safe and stable operation of DC-side bus voltage. Then, the generator stator-side reactive output capability is preferentially considered to provide the reactive power that shall be outputted by the grid-side converter and the stator of DFIG while ensuring the safe port voltage. Finally, the formula for the operation range of the safety voltage is proposed according to the operation range of the grid-side converter and DFIG, thus to provide the basis for checking whether the internal components of DFIG can normally operate during the high voltage ride-through thereof.
