摘　　要：针对宁夏输电线路经常因大风引起故障的问题,结合地形及大气环流等因素,研究了宁夏风区的分布特征,并根据风区分布特征提出了宁夏输电线路防风策略。应用结果表明:防风策略实施后,输电线路因大风引起的故障明显减少,避免了输电线路风偏、舞动故障的发生,大大减少了宁夏电网因非计划停运造成的经济损失,保证了输电线路的安全稳定运行。Aiming at the problem of the gale causing transmission line faults in Ningxia, combining with the terrain and atmospheric circulation factors, researches wind zone distribution characteristics, and puts forward wind-proof strategy of Ningxia transmission line. The application resuh shows that： after the wind-proof strategy implemented, reduces the transmission hne fauh due to the gale, avoids windage yaw and galloping faults happening, reduces greatly economic loss causing by non-scheduled shutdown of Ningxia power grid, and ensures the safe and steady operation of transmission line.
