应用皮尔逊相关系数算法查找异常电能表用户

摘要

A user��s watt-hour meter may have some abnor-malities, one of them is the overproof of negative errors. This will lead to district line loss higer. In order to position the users with ab-normal watt-hour meters accurately, the article chooses to use pear-son correlation coefficient algorithm. This kind of algorithm is quick, accurate and efficient.The article starts with the relationship between line loss and electric energy, then expatiates the theory of the algorithm, and gives some examples of how Taizhou Power Sup-ply Company uses the algorithm to search for the users with abnor-mal watt-hour meters and some matters in using the algorithm.%用户电能表异常，尤其是负误差超差，会导致台区线损偏高。为了准确定位异常电能表用户，选择皮尔逊相关系数算法进行计算，该算法具有速度快、定位准、效率高的优点。从线损电量与用户电量关系出发，阐述了皮尔逊相关系数算法的原理，介绍了泰州供电公司运用皮尔逊相关系数算法查找异常电能表用户的实例，提出采用该算法在查找异常电能表中的注意事项。
