智能电能表故障风险预估算法的研究*

智能电能表随着国家电网的大力推广应用,它在使用中是否发生故障已成为令人关注的问题。为此,研究并编制了智能表故障风险预估算法。该算法针对智能电能表的首检数据,先按规程判定出性能良好的电能表,再将这些良好电能表分别进行横向筛查和纵向筛查,最后依筛查结果划分为四个风险等级,可作为检修维护的参考数据。用大量数据对算法进行了验证,结果符合本文预期值,表明算法正确合理。

Research on the algorithm of fault risk prediction for the smart meter

With the popularization and application of the national grid, malfunctions of the smart meter in use has become an attraction. Therefore, the algorithm of fault risk prediction was studied and compiled. The algorithm aims the first measurement data of smart meter. First, determined the meters with good performance according to the regulation. Then, these meters were screened by horizontal and longitudinal. Eventually, these meters were divided into four risk levels according the screening results, which can be regarded as the reference of maintenance. The algorithms were validated by millions of meters and the result satisfied the expected results in this paper, which means that the algorithms were reasonable.
