Abstract | The invention discloses a safety early warning method and system after icing of a power transmission conductor, and the method comprises the steps: S1, carrying out the calculation of an actual safety coefficient of a high suspension point through combining an icing state monitoring coefficient of the power transmission conductor; s2, when the actual safety coefficient of the high suspension point is smaller than a threshold value, early warning is carried out; and S3, when the actual safety coefficient of the high suspension point is greater than or equal to a threshold value, calculating to obtain the conductor sag at the moment, calculating to obtain the insulation distance of the transmission conductor at the moment according to the conductor sag at the moment, and if the insulation distance of the transmission conductor at the moment exceeds a safety value, performing early warning. According to the invention, the operation state of the transmission conductor in the icing state is scientifically and visu |
