The invention discloses a multi-source heterogeneous data fusion method, device and system for power transmission line monitoring. The method comprises the following steps: acquiring initial monitoring data acquired by multiple types of sensors on a to-be-monitored power transmission line, and taking all initial monitoring data acquired by the same type of sensors as an initial monitoring data set to obtain multiple initial monitoring data sets; performing data preprocessing on all the initial monitoring data in each initial monitoring data set to obtain a plurality of pieces of first fusion data, and performing feature extraction on each piece of first fusion data to obtain a plurality of pieces of second fusion data; and selecting a plurality of second fusion data as target fusion data according to a predefined power transmission line anomaly judgment strategy, and performing data fusion on all the target fusion data to obtain third fusion data. According to the invention, the multi-source heterogeneous dat
