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.
