In the engineering design of substations

the calculation of wind-induced swing of flexible conductors is one of the core contents in the design of switchgear area.This calculation directly determines the phase-to-phase distance of conductors

the conductor-to-ground distance

and the design of gantry spans.It plays a crucial role in achieving an economical

reasonable

compact

and optimized layout of substations.At present

relevant design codes have not clearly specified the specific calculation formulas for wind-induced swing

and the algorithms listed in current design manuals are not entirely consistent.This paper systematically sorts out the calculation methods for wind-induced swing of flexible conductors from multiple references

including Handbook of Electrical Power Engineering Design(Substation Design)

Handbook of Electrical Power Engineering Design(Overhead Transmission Line Design)

and Design and Operation of Electrical Components in 500 kV Substations.Through analysis

comparison

and combined with case study analysis

it proposes an improved set of calculation methods

providing a reliable basis for enhancing the safety and economy of substation design.
