摘　　要：酒泉至湖南±800 kV特高压直流实现风电与火电打捆外送电力8 000 MW。为得到直流风火打捆的比例,通过分析直流送端风火打捆的必要性,结合甘肃实际风电出力特性对直流配套的风电一火电一直流理论输送容量进行计算,比较不同配套火电规模下火电及直流利用小时数、弃风电量以及直流送电曲线,最后给出合理的酒泉直流风火打捆比例及合适的配套火电规模范围。The ±800 kV UHVDC project from Jiuquan to Hunan is designed to send out power of 800MW, which transmits electricity through wind and thermal power bundling. In order to get the ratio between wind and thermal power, the necessity of wind and thermal power bundling is analyzed. Combined with the Gansu wind power output characteristics, HVDC sending capacity of wind power-thermal power-transmission capacity in theory is studied. Considering the thermal power and HVDC using hours, abandoned electric quantity of the wind, HVDC transmission curve ere,the reasonable ratio of wind and thermal power bundling of HVDC sending is put forward.
