The interest in the utilization of offshore wind power is increasing
significantly. Due to the shortage of in-land locations for wind farm and the
wind speed offshore is potentially higher than that of onshore, which leads to
a much higher power production. In this thesis a large offshore wind farm is
modeled using Matlab simulation package. In the simulations active stall
regulated wind turbines driving fixed speed asynchronous generators are
used. Two different types of interconnections are modeled and compared,
one is the Voltage Source Converter (VSC) based HVDC link and the other
one uses high voltage AC (HVAC) cable interconnection. Transmission
faults are simulated in each system and the transient response are examined.
Three phase fault and single line to ground fault are used to compare the
performance of the VSC based HVDC interconnection system and HVAC
interconnection. It is found that compared to the traditional HVAC
transmission, the VSC based HVDC transmission would have better
performance under various system disturbances.
