摘要

海上风电场中的直流集电电网在效率和投资成本方面具有优势。双有源电桥(DAB) dc-dc变换器系统可用于提高风力发电机组的直流输出电压。电压等级的提高减少了布线的工作量，提高了系统效率。本文介绍了用于海上中压直流(MVDC)电网的DAB变换器系统的优点。同时，研究了考虑尾流效应和电网损失的风电场集群优化设计，以实现发电效率最大化。

Optimum design of medium-voltage DC collector grids depending on the offshore-wind-park power

DC collector grids within offshore wind park offer advantages regarding efficiency and investment costs. Dual-active bridge (DAB) dc-dc converter systems can be applied for stepping-up the dc output-voltage of wind turbines (WT). The increase of the voltage level reduces the effort for cabling and increases the system efficiency. Within this paper, the advantage of DAB converter systems used in offshore medium-voltage dc (MVDC) grids is presented. Also, the optimum design of wind park clusters regarding the wake effect and grid losses is investigated to maximize the energy yield.
