Description: 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. Platform: |

Description: This report is the conclusion of the post-course work following the Nordic PhD-course on
Wind Power, which was held on Smø la 5th – 11th June 2005. The goal of the project was to
construct a Simulink model of a 2.5 MW wind turbine with direct-driven permanent magnet
generator connected to the grid via a back-to-back three-phase converter. The model was then
to be tested in simulation runs. Platform: |
