基于CET变换器的串联型风电全直流系统研究OA北大核心CSTPCD
A series connected wind power full DC system based on a CET converter
串联型汇集送出方案被认为是规模化远海风电全直流系统最可能实现的方案.为避免串联型直流风电机组因风电机组间耦合特性引起的过电压现象和风功率损失,使系统实现高压直流送出和具备直流故障自清除能力,提出了基于容性能量转移原理DC/DC变换器(capacitive energy transfer principle based DC/DC transformer,CET-DCT)的新型串联系统.该系统拓扑中海上升压站为 CET-DCT 结构,并采用基于混合…查看全部>>
The series-connected collection and transmission scheme is considered as the most feasible solution for large-scale offshore wind power full DC systems.To avoid overvoltage phenomena and wind power loss caused by the characteristics of series-connected DC wind turbines,to enable the system to achieve high-voltage DC transmission,and self-cleaning capability during DC faults,a novel series-connected system based on the capacitive energy transfer principle DC/…查看全部>>
