在变电站工程设计中，软导线的风偏摇摆计算是配电装置设计的核心内容之一。风偏摇摆计算直接决定了导线相间距离、相对地距离，以及构架跨度的设计，对实现变电站经济合理、紧凑优化布置具有重要作用。目前，国内相关设计规范尚未明确风偏摇摆的具体计算公式，且现行设计手册中所列算法亦不尽一致。本文系统梳理了《电力工程设计手册：变电站设计》《电力工程设计手册：架空输电线路设计》《500 kV变电所电气部分设计及运行》等多部资料中关于软导线风偏摇摆的计算方法，通过辨析比较并结合算例分析，提出一套改进后的计算方法，为提升变电站设计的安全性与经济性提供了可靠依据。

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.
