Cable parameter prediction method and system

The invention discloses a cable parameter prediction method and system. The method comprises the following steps: acquiring coordinates of a to-be-predicted cable; inputting into a pre-constructed multiple linear regression model to obtain electrical parameters of the to-be-predicted cable; the construction of the multiple linear regression network comprises the following steps: constructing an initial multiple linear regression model; extracting electrical parameters of different positions of the cable to be predicted and coordinates of corresponding positions; and constructing a sample set according to the extracted electrical parameters and the coordinates of the corresponding positions, performing coefficient calculation on the initial multiple linear regression model by using the sample set to determine multiple linear regression model coefficients, and obtaining a final multiple linear regression model according to the multiple linear regression model coefficients. The method has ...
