摘　　要：研究了好天气下1000k V特高压交流单回输电线路运行时无线电干扰的统计特性。通过在我国晋东南–南阳–荆门1000k V特高压交流试验示范工程单回输电线路附近建立长期观测站,获得了该线无线电干扰的海量测量数据。采用基于非参数统计方法的单样本K-S检验,重点对2010年3~9月份中100个好天气下的无线电干扰测量数据进行了统计分析,利用β（g,h）分布的多态性和灵活性特征,提出了剔除无线电干扰测量异常值的方法。研究表明,好天气条件下1 000 k V特高压交流单回输电线路无线电干扰与湿度密切相关,且春季与夏秋季的相关性相反;与风速和温度存在弱相关性,且相关系数较小。This paper analyzed the statistical characteristics of radio interference（RI） of 1 000 k V UHV AC single-circuit transmission line under good weather condition. Massive RI measurement data has been acquired by establishing a long-term observation station close to Jindongnan-NanyangJingmen 1 000 k V UHV AC pilot project single-circuit transmission line. Based on a non-parametric statistical method, single-sample K-S test has been employed to statistically analyze the 100 days RI under good weather from March to September, 2010. By means of polymorphism and flexibility of β（g,h）distribution, one outlier rejection method has been raised. Statistical result shows that the correlation between RI and humidity is close, which is opposite in the spring and summer autumn, and the correlation between RI and wind speed is weak correlation, and the correlation coefficient is small.
