The invention discloses a multi-metering abnormal event correlation analysis method, and relates to an abnormal event analysis method. At present, only a single metering abnormal event is analyzed, the workload is large, part of alarm information cannot be effectively analyzed and processed, and the improvement of the fault accuracy is limited. In order to improve the abnormal alarm data utilization rate and the abnormal diagnosis accuracy, the association degree of every two abnormal events is calculated through classification and screening of historical data, whether the occurrence of the two abnormal events has a causal relationship or not is visually seen, results are screened, and the accuracy is improved. Finally, a threshold value is set for the association degree to realize screening of concurrent abnormal event combinations. According to the technical scheme, the concurrent abnormal event combination is effectively discriminated, so that the accuracy and integrity of analysisand utilization of the metering abnormal event are improved.
