750kV同塔双回交流输电线路电磁环境分析
|
摘要
为了有效研究750kV同塔双回交流输电线路电磁环境,采用模拟电荷法进行电场计算、毕奥—萨瓦定律进行磁场计算、激发函数法及GE公式进行无线电干扰和可听噪声计算,分析相序布置、导线类型、导线对地最低高度、天气情况对电磁环境的影响。依据相应的电磁环境控制指标,提出750kV同塔双回交流输电线路设计要求:相序布置应采用逆相序;输电线路通过邻近民房时下相导线最低点距地高度不应低于19m,线路通过公众活动地区或跨越公路处时下相导线最低点距地高度不应低于13m,线路跨越农田时下相导线弧垂最低点距地高度不应低于10m。
In order to effectively analyze electromagnetic environment of 750 kV double-circuit transmission line,the charge simulation method was used for electric field calculation,the Biot-Savart law was used for magnetic field calculation,and the excitation function method and GE formula were used for audible noise and radio interference calculation in this paper.The influence regularities of electromagnetic environment with different phase sequence arrangement,different types of wire,different wire lowest height and different weather conditions were deeply analyzed.According to the corresponding electromagnetic environment control indexes,some suggestions for the 750 kV doublecircuit transmission line design were proposed.Reverse phase sequence should be used for phase sequence arrangement.The lowest height of phase wire which is adjacent to houses should be more than 19 m.The lowest height of phase wire which is across the public area or across the road area should be more than 13 m.The lowest height of phase wire which is across the farmland should be than 10 m.
