Zusammenfassung:The invention discloses a power transmission line dynamic thermal capacity limit prediction method capable of tracking environmental factor time-varying characteristics, and belongs to the field of power transmission network line operation state evaluation in a power system. Firstly, main influence factors of the DTR are determined; and establishing a DTR prediction model considering the influence degree time-varying characteristics of the environmental factors. Secondly, obtaining DTR time sequence prediction model training data, and training a DTR time sequence prediction model; and finally, performing DTR prediction by using the DTR time sequence prediction model, and finally realizing rolling prediction. According to the method, the FoecastNet prediction model of the time-varying weight structure is adopted, so that the problem that the environment input feature weight of a traditional time sequence prediction model is not changed can be effectively solved, the change of the influence degree of environmen
