The invention discloses a dynamic setting method of a differential threshold for online monitoring of transformers. The method includes the following steps: classifying and identifying the historicaldata of a transformer monitored in different operating environments and seasons; preprocessing the classified and identified historical data, and removing abnormal data from the historical data; usinga method based on K-Means clustering to dynamically calculate the discrimination threshold of the transformer based on the historical data with abnormal data removed; and based on a Spark distributedparallel computing framework, constructing a transformer equipment comprehensive warning model of threshold alarm based on the discrimination threshold and trend analysis, so as to differentially monitor the discrimination threshold of the transformer. The calculation time of the dynamic threshold is greatly shortened while the accuracy of alarm is improved.
