AbstractThe number of installed wind turbines is growing every year as the need for energy increases in an exponential manner. As the wind turbines are trying to fulfil these requirements, the demand for output power from each individual turbine is increasing as well. Although this is great, implementation of new technologies such as direct drive superconducting generators are required as they have a great potential for becoming a great contender for satisfying the increasing demand of individual turbine power output. The efficiency and the mass reduce by using this technology but other issues have to be checked regarding its transient performance. Due to the low sub-transient, transient and synchronous reactance, compared to a conventional machine, the transient properties such as short-circuit current, field current and electromagnetic torque is much higher. This may cause problems as high values may damage the windings and turbine properties and even cause the superconducting field windings to lose its superconducting property. The thesis report will try to model a superconducting generator for a 10MW wind turbine and analyse its transient properties. Also several important parameter calculations will be made taking into account the saturation due to iron in the generator. This simulation will be made for three different topologies of generator while taking into account their own individual generator geometry.
