摘　　要：针对位于野外有风环境下的太阳能电池板表面易于积累灰尘,利用三相行波电帘技术进行除尘时,风力可能会对除尘效率以及灰尘的定向移动情况产生干扰的问题,分别在面板倾斜角度θ为0°、10°、20°和30°以及风力等级分别为0级、1级、2级和3级的情况下,利用析因分析法设计了分组实验,研究了三相行波电帘除尘技术的抗风干扰性能,测试了倾斜角度在0°~30°和风力等级在0级~3级范围内的除尘效率,并拍照记录了0级、1级、2级和3级风速下的灰尘定向移动情况。研究结果表明,三相行波电帘除尘技术具有较好的抗风干扰性能,风力不会降低除尘效率,各种风速和倾斜角度下的除尘效率均在96%以上,无风情况下的灰尘具有较好的定向移动特征,但有风情况下的定向移动会被破坏。Aiming atsolving the problems of dusts accumulation on solar power generation system（ SPGS）,traveling wave electric curtain method was investigated. As the SPGS was usually located in wild environment,dust removing efficiency and particle＇s directional movement may be interfered by the wind in the wild environment. Thus,the analysis of anti-interference of wind force was proposed. The ability of antiinterference of wind force was tested by comparing the performance in 0,1st,2nd,and 3rd level windand inclining angle of 0°,10°,20°and 30° by using Factor Analysis Approach（ FAA）. The results indicatethat dusts removal efficiency in all the cases are above 96%,but directional migration is disturbed in the wind speed 0. 5 m / s ~ 1. 7 m / s and nearly all the dusts leaped out from electric curtain are fly-off in wind speed larger than 3. 5 m / s. Therefore,the electric curtain method is able to anti-interference of wind force and suitable for wild environment.
