Wind power collection and transmission with series connected current source converters

In this paper, series connected DC current source converter based Wind Turbine Generation System (WTGS) is proposed. Not only a multi-phase generator but also a group of wind turbine generator can be linked easily with multiple series connected current source converters. It is expected that the system can have higher availability and lower initial setup cost compared to conventional voltage source converter based WTGS. The modeling and the control strategy for the proposed system is investigated. A 3 MW system with three series connected current source converters has been simulated by the computer program. The effectiveness of the proposed control strategy is verified by the simulation.
