摘要

This article describes the second part of a larger investigation of dynamic interaction between variable-speed wind turbines equipped with doubly-fed induction generators (DFIG) and the power grid. A simulation model is applied for dynamic stability investigations, with the entire power grid subjected to a short-circuit fault During the grid disturbances, the DFIG converter is found to be the most sensitive part of the wind turbine. Therefore the electrical currents are determined using the transient generator model. The converter action is crucial for wind turbine operation associated with such disturbances, especially regarding tripping or uninterrupted operation.
