摘　　要：笔者针对广西沿海地区地域特点,从小孤立档和桉树基准高度两个方面对风电场35 kV集电线路的设计优化策略进行了研究。通过改进小孤立档的挂线工艺,无须考虑挂线过牵引效应,有效减少了小孤立档的终端塔用量;同时,提出一种基于桉树轮伐期确定基准树高的方法,使集电线路导线高度从常规设计的29 m降至25 m,全面降低集电线路跨越林区所需铁塔高度。研究成果可为其他具有类似地域特点的地区以及110 kV以上电压等级线路设计提供参考。According to the regional characteristics of Guangxi coastal areas the design optimization strategy of 35 kV collector line in a wind farm is studied from two aspects of small isolated span and eucalyptus benchmark height.By improving the hanging process of the small isolated span it is not necessary to consider the over-traction effect of the hanging line which effectively reduces the amount of terminal tower of the small isolated span.At the same time a method for determining the reference tree height based on the rotation period of eucalyptus is proposed which reduces the height of the collector line from 29 m to 25 m and comprehensively reduces the height of the tower required for the collector line to cross the forest area.The research results can provide reference for the design of other regions with similar regional characteristics and lines with voltage levels above110 kV.
