Abstract

The invention provides a method for calculating the phase distance between incoming and outgoing line gears of a power transmission line. The method comprises the following steps of: representing coordinate positions of wires in a space by using a space catenary equation; and calculating the wire phase distance by using a successive approximation algorithm. The method has the beneficial effects that a spatial catenary equation is used for accurately representing a model of the spatial position of the wire, and meanwhile, the calculation speed is greatly increased by using a successive approximation algorithm.

Description

technical field [0001] The present disclosure relates to the field of calculation of the phase distance between the incoming and outgoing line stalls of a power transmission line, and in particular to a calculation method for the phase distance between the incoming and outgoing line stall conductors of a transmission line. Background technique [0002] At present, there is no unified calculation formula for the calculation of the phase spacing of the incoming and outgoing line stalls of the transmission line, and the calculation of the conductor spacing involved in the existing design manual is limited to the calculation of continuous stalls. The wires entering and exiting the line stalls are affected by factors such as the phase sequence arrangement of the wires, the relative position and height difference between the terminal tower and the substation hanging point, and the rotation angle of the terminal tower. There are many ways to arrange the wires, which cannot be easily...
