基于大数据分析的暂态电能质量综合评估方法
Comprehensive Evaluation Method of Transient Power Quality Based on Big Data Analysis
摘要
Abstract
A transient power quality assessment method is proposed based on Naive Bayes classification in the architecture of big data processing. The data sources are extended to power grid monitoring data, power customer data and public data, and the assessment se-verities are classified into normal state, abnormal state, critical state, and failed state according to the results of Naive Bayes classifi-cation. A Naive Bayes classification method based on MapReduce to realize power quality assessment is designsed. In the classifier training phase, massive historical data are used as the distributed learning object, and assessment rules are generated periodically. In the state assessment phase, each assessment node updates the assessment rules generated by the training phase, generates real-time e-valuation of the samples from the stream processing framework, and evaluates the power quality state according to the current rule. Ex-periment results show that the transient power quality evaluation method based on big data analysis presented in this paper is feasible, and achieve good results both in classification accuracy and processing speed.关键词
