Study and design of a DC/DC converter for series connected wind farms

Abstract

In this Master Thesis, the design of a DC/DC converter for a series connected DC wind park was investigated. The features of this kind of wind park were presented, and possible topologies of the converter were studied. Finally its advantages and drawbacks for the specific application were discussed. It was found that the most appropriate model was the full bridge converter, which there was theoretically analyzed. One investigated aspect was how the converter performance was affected by the transformer parameters. Then, an economical criteria was defined to choose the most suitable one: the energy cost. At last the selected design was simulated in Pspice® in order to check that it satisfies the application requirements, and the simulated waveforms were compared with those found from the theoretical study.
