Big Data Analytical Method for Operating State Assessment of Distribution Transformer
摘要
Abstract
In order to raise fault prediction level and working life of distribution transformers,a big data analysis method for distribution transformer operating state assessment is presented,a business process architecture which combined regular assessment method and big data method is constructed.Combined with multi-source data of distribution network,analyze the data type,source and pretreatment methods for distribution transformers operating state,then quantify the properties correlation between each factor through data stream processing method.The assessment model of distribution transformer operating state based on information entropy theory is developed,it combines the big data online assessment and regular comprehensive assessment methods,achieves the unity of probability predict and specific indicator assessment.The instance shows that the result can effectively reflect the overall operating state of distribution transformers.关键词
