| dc.description.abstract | in order to eliminate the bulky and costly offshore substation, a new offshore wind farm
configuration has recently been proposed: series-connected configuration. among the seriesconnected configurations, the pulse width modulation current source converter (csc)-based one is
considered a good candidate. in this thesis, a new pwm csc-based wind energy conversion system
is proposed for the series-connected wind farms. compared with the previous work, the proposed
topology reduces the cost and the manufacturing pressure of the system. a new control scheme is
proposed to solve the voltage and current imbalance problem of the proposed configuration. in
addition, the optimal modulation scheme is investigated for the series-connected cscs. simulation
results are provided to assist in the investigation and verify the performance of the proposed
configuration and control schemes. | en_us |
