论文摘要
本文提出了一种新颖的集成多部双向双向反向电源转换器，用于容纳电池和超级电容器的4型风力涡轮机，以存放能源。与传统配置相比，电路拓扑减少了4个开关。此外，由于嵌入了相位腿中的双buck结构，电路没有短路路径，因此它可以承受比正常相位腿的短路时间更长的时间，并防止反向电流在转弯恢复中。使用电池和超级电容器的混合能源存储系统的使用有助于使风阵下的功率输出平滑，并在网格故障条件下稳定DC-Link电压。案例研究是使用1.5 MW的风力涡轮机系统进行的。为理论验证提供了仿真结果。
This paper proposes a novel integrated multiport bidirectional back-to-back power converter for a type-4 wind turbine that accommodates a battery and supercapacitor for energy storage. The circuit topology reduces 4 switches compared to the traditional configuration. Moreover, owing to the dual-buck structure embedded in the phase leg, the circuitry has no short-circuit path, therefore it withstands short-circuited events for a much longer time than the normal phase-leg and prevents the reverse current in turn-off recovery. The use of a hybrid energy storage system with battery and supercapacitor helps smooth out the power output under wind gusts and stabilizes the DC-link voltage under grid fault conditions. The case studies are carried out with a 1.5 MW wind turbine system. Simulation results are provided for the theoretical validation.
