采用“直流汇集-直流传输”的全直流海上风电场具有设备体积小、系统损耗低、没有无功电压问题等优势,其核心设备高压送出DC/DC变换器亟须突破传统变换器功率低、电压受限等技术瓶颈。文中首先根据全直流风电组网技术需求,将模块化多电平变换器与输入串联输出串联型DC/DC变换器组合,提出一种复合模块化结构。其次,为实现DC/DC变换器的高变比功能,提出了基于双重移相的

调制策略,并针对该调制策略的特点改进了电容电压均衡算法,有效降低了器件的开关频率。最后,在MATLAB/Simulink仿真软件上搭建模型,验证了所提变换器拓扑及策略的有效性。
The full-DC offshore wind farm with DC collection and DC transmission has the advantages of compact equipment size
low system loss and no reactive voltage problem. The high-voltage output DC/DC converter is the core equipment of the full-DC offshore wind farm
which urgently needs to break through the technical bottlenecks of traditional converters such as low power and voltage limitation. Firstly
according to the technical requirements of full-DC wind power networking
this paper proposes a composite modular structure combining the modular multilevel converter with the input-series output-series DC/DC converters. Secondly
in order to realize the high ratio function of the DC/DC converter
the

modulation strategy based on the double phase shift is proposed
and the capacitor voltage equalization algorithm is improved according to the characteristics of the modulation strategy
which effectively reduces the switching frequency of the device. Finally
the model is built on MATLAB/Simulink simulation software to verify the effectiveness of the proposed converter topology and strategy.
