摘　　要：为分析省地负荷特性的差异与关联,文章建立了省地负荷关联特征模型对省地负荷特性进行了相关性分析,采用Spearman相关系数获得省地负荷特性的关联性。相关系数越大的地市,其负荷曲线与全省负荷曲线一致性越好,对指导省地负荷分解策略有一定作用。In order to discover the differences and correlations of load characteristics between provincial and municipal areas,this paper establishes a provincial-municipal load correlation characteristic model to conduct a correlation analysis of load characteristics.The Spearman correlation coefficient is used to obtain the correlation of load characteristics.The larger the correlation coefficient of a city,the better the consistency between the load curve and the provincial load curve,which plays a certain role in guiding provincial-municipal load decomposition strategy.
