Application of Transformerless High Gain DC/DC Converter for Grid-connected Offshore Windfarms
並列摘要
In this paper, operation and control of an offshore wind farmusing typical configuration is considered. Commonly, the offshore wind farms are connected to the grid using HVDC transmission system in order to decrease power losses and voltage sag. In the proposed configuration a new cascaded structure of transformerless high gain DC/DC converter is appliedinstead of a power transformer. The proposed DC/DC converter can boost voltage level and regulate DC link voltage in output of permanent magnet synchronous generator (PMSG). By adjusting DC link voltage in a suitable value, the maximum active power can be received from PMSG. The main advantage of the proposed configuration is that there aren’t anypower transformer and back-to-back converter inoutput of PMSG. The simulation results confirm good operation of the proposedconfiguration in various wind speeds. Also experimental results of the introduced prototype of the DC/DC converter show the effectiveness of this converter in high gain mode.
