摘要
对输配电系统中所发生的电能质量(PQ)干扰事件的分析有利于对电力监控和调度,因此需要采用针对性的解决方案对这些数据集进行处理。为此,文中提出了一个简单而有效的元数据数据库模型来分析电力系统中大量的电能质量干扰事件。使用该模型构建的数据库可用于存储数据,从而对干扰事件进行描述和分析。文中提出的模型定义了五个类来存储与PQ干扰事件相关的数据:事件、时间序列、描述、软件分析和IEEE干扰分类。最后,通过对该模型的使用演示表明,该数据模型能够作为唯一标识准确记录PQ干扰事件的主要特征。
The analysis of power quality(PQ)interference events occurring in transmission and distribution systems facilitates power monitoring and scheduling,so these data sets need to be addressed with a targeted solution.For that reason,a simple and effective metadata database model is proposed to analyze a large number of power quality interference events in the power system.A database built by this model can be used to store data to describe and analyze interference events.The proposed model defines five classes to store data related to PQ interference events:events,time series,descriptions,software analysis,and IEEE interference classification.Finally,the demonstration of the use of the model shows that the data model can be used as the unique feature to accurately record PQ interference events.
