摘要

最近，由于海上风力更强、更稳定，发电量更高，海上风力发电场备受关注。直流到直流电源变换器成为解决海上高压直流输电风电系统安装过程中所面临的挑战的较好的解决方案之一。本文介绍了一种基于电容箝位(CC)模块的多电平模块化直流变换器，适用于大型海上风电企业。为了实现最大的系统效率和最小的开关损耗，采用了软开关技术。对基于CC模块的电压三倍器和2n+1级联配置进行了理论分析。在MATLAB/SIMULINK中对15电平级联无开关变换器进行了仿真。实验结果产生的电压增益为15。实验结果验证了理论分析，证明了所提拓扑的可行性。

HVDC-Based Multilevel Modular Power Converter for Offshore Wind Farms

lately, the offshore wind energy farm has drawn a significant attention due to a stronger and steady wind at sea, which result a higher power generation. DC to DC power converters become one of the better solutions for challenges faced during the installation of the HVDC transmitted offshore wind energy system. This paper introduces a multilevel modular dc to dc power converter based on capacitor-clamped (CC) module, for the large power offshore wind firms. To achieve the maximum system efficiency and minimal switching losses, a soft-switching technique is embrace. Theoretical analysis is perform for voltage tripler and 2n+1-level cascaded configuration based on CC modules. The 15 level cascaded switchless based converters are simulated in MATLAB/SIMULINK. The experimental result produced voltage gain of 15. The experimental results validate the theoretical analysis and prove the possibility of the suggested topology.
