摘要
为了提升电力信息数据质量,解决当前数据质量优化方法存在的优化效果不佳的问题,提出基于数据中台的电力信息数据质量优化方法。利用数据中台采集全域电力信息数据,将采集数据还原为十进制电力数据,通过确定聚类中心和相似度计算两个步骤,实现初始电力数据融合。针对缺失、噪声以及重复数据制定清洗方案,最终通过输出控制,完成电力信息数据质量的优化操作。实例分析结果表明,通过优化方法的应用得到的电力信息数据的完整性、精准性和及时性均满足设计要求,即得到良好的数据质量优化效果。
In order to improve the data quality of power information and solve the problem of poor optimization effect of current data quality optimization methods,a power information data quality optimization method based on data center is proposed.The whole area power information data are collected by the data center,and the collected data are restored as decimal power data.The initial power data fusion is realized by determining the cluster center and similarity calculation.The cleaning scheme is formulated for missing,noise and duplicate data,and finally the optimization operation of power information data quality is completed through output control.The example analysis results show that the integrity,accuracy and timeliness of the power information data obtained by the application of the optimization method meet the design requirement,i.e.,a good data quality optimization effect is obtained.
