Novel Wind Power Plant Topology for DC Power Transmission Systems

摘要

A promising topology to interconnect wind power plants is proposed. The advantages of this series-connected system over the conventional parallel system are first discussed, and a control strategy for the series-connected system is examined in order to realize optimum wind energy usage. The dynamic performance of the series-connected system is investigated through simulation and experiments while an effective method of realizing high-quality output power is also shown. Finally, a novel topology featuring wind turbine/generators connected in series that is suitable for DC power transmission is introduced, which can enlarge the scale of the wind power plant without increasing the system voltage level.
