摘　　要：首先对典型海上高压全直流风电场结构进行初步分析,将其中性能相对较高的串-并联和新型混联矩阵两种结构作为研究重点,以成本-效益为中心,考虑可靠性,尤其是结合个别机组停机带来的不同影响等动态因素,通过理论推导建立两种结构的动态成本-效益分析模型;然后利用该模型,以某实际风电场数据为例进行定量分析,详细比较两种结构的经济性优劣,得出了基于混联矩阵结构的全直流风电场经济性优于串-并联结构直流风电场的结论。Firstly,this paper makes a preliminary analysis of the structure of a typical offshore high-voltage full DC wind farm.Focusing on the comparative study of the series-parallel structure and the new hybrid matrix structure,the dynamic cost-benefit analysis model of the two structures is established by theoretical derivation,with the cost-benefit as the core and considering the reliability.The economic advantages and disadvantages of the two structures are quantitatively compared in detail,and it is concluded that the economy of the full DC wind farm based on the hybrid matrix structure is better than the series parallel structure.
