摘　　要：空冷岛轴流风机群的优化设计与运行,对直接空冷机组降低厂用电率具有重要意义。以华能上安电厂三期工程2×620MW超临界直接空冷机组为例,提出了风力机与电动机双动力驱动轴流风机群的方案,建立了风力机输出功率计算模型,进行了植入风力机的轴流风机群节电分析。计算表明,在机组负荷、气温和风速不变的条件下,接入风能的#5机组与#6号机组轴流风机群节电均为918kW·h,降低风机厂用电率分别为0.184个百分点和0.186个百分点。Optimized design and operation of the air-cooled island axial fan cluster have a great significance to reduce auxiliary power ratio of direct air cooling units. This paper proposed a program which drove the axial flow fan cluster by dual power of wind turbine and motor, taking the 2x620MW supercritical direct air cooling units of the third-phase project of Huaneng Shangan Power Plant as example, and established the computational model of the wind turbine output power to make an power saving analysis of axial flow fan cluster implanted wind turbines. The calculations show that #5 and #6 units axial flow fan cluster saved equal power by 918kW.h in constant unit load, temperature and wind speed. Accordingly, they reduce the auxiliary power ratio of wind turbine by 0.184 and 0.186 percentage points.
