The invention relates to a reactive voltage cloud edge cooperative control method based on a Km-FZM model, and the method comprises the steps: sensing end layer information through an edge server, and carrying out the judgment of a bus and a branch; constructing a cooperative control model, namely a Km-FZM model, in which a K-means model and an improved fifteen-zone graph control strategy are fused; and the edge server regulates and controls the data in the defined range at the edge layer according to a fifteen-zone graph control strategy, and if the reactive power is not balanced, the feature data outside the defined range is uploaded to the cloud for overall clustering optimization, and then optimization is performed at the edge layer. According to the method, the Km-FZM control model is combined with cloud edge cooperation, the defect that the control sequence is disordered and complicated is effectively overcome, voltage reactive power control and reactive power optimization are completed ...

The invention relates to the technical field of computer vision, in particular to a power line reconstruction method based on BEV view assistance. Comprising the steps of ground point removal, noise point screening, calculation of the number of power lines in the vertical direction, coarse reconstruction of the power lines and fine reconstruction of the power lines. According to the method, a BEV view is introduced as an assistance, ground points and noise points are removed from power line 3D point cloud data, the accurate number of a plurality of power lines which coincide into one line in the vertical direction is accurately calculated, then rough reconstruction and fine reconstruction are carried out in sequence, and finally clear and complete power line point clouds are obtained. The condition of the power line can be better judged, more efficient and more accurate power transmission line inspection operation is realized, the labor cost is reduced, and more reliable distribution line ...

The invention relates to the technical field of power distribution network fault location, in particular to a traveling wave fault location improvement method for power distribution network fault location analysis. Comprising the following steps: measuring three-phase voltage at two ends, decomposing a fault signal by using a feedback-based VMD blind source separation algorithm to obtain a plurality of IMF signals which contain rich fault information, demodulating the decomposed signals by using a TEO energy operator method to form time and energy spectrums, and determining whether the time and energy spectrums are abnormal or not. And observing the time of a point with abrupt energy change after demodulation, and substituting the time into a double-end distance measurement formula which does not need to measure the wave velocity to carry out fault location. In the design of the invention, the combination of the feedback-based VMD blind source separation algorithm and the TEO energy algorithm ...
