Doubly fedi induction generator Model

With increasing wind penetration in power systems, many national grid codes will demand complete models and simulation studies under different system conditions in order to ensure that the connection of a wind farm will not have a detrimental impact on the network to which it will be connected. Hence a dynamic model with reduced-order double cage representation for the DFIG and its associated control and protection circuits has been developed. It was then used to simulate the response of wind turbine to network faults on a simple two busbar system.
