Zusammenfassung:The invention discloses a multi-stage power transmission and distribution line operation state early warning method based on multivariate data fusion analysis. The method comprises the following steps: acquiring multivariate data of a power transmission and distribution line; constructing a transmission line operation state detection model based on a BP neural network; constructing a distribution line operation state detection model based on a BP neural network; a power transmission and distribution line operation state early warning model based on a BP neural network is constructed, the power transmission and distribution line operation state early warning model based on the BP neural network is updated to a power transmission and distribution line operation early warning system, and high-voltage/medium-voltage power transmission line data and high-voltage/medium-voltage/low-voltage power distribution line data collected on line are detected. And corresponding early warning is carried out according to a dete
