摘　　要：新疆750kV特高压输电线路是中国新疆地区实施优势资源转换战略的重要组成部分,在能源战略布局上可实现南北疆电力互供、水电与光伏互补,提高电网供电可靠性及互供能力、新能源接纳能力。新疆750kV输电网络覆盖区域广,途径地形复杂。大风是新疆地区典型的气象特征,也是线路故障的主要外力因素之一。新疆750kV线路运维过程中需要掌握大风发生的时空特征,以便进行有针对性维护。文中结合新疆地区的地形遥感数据以及2011年至2015年的新疆750kV主要线段沿线的风速、风向数据,分析了750kV线路沿线的海拔、坡度坡向、年平均风况,6级以上大风风况等特征,分析结果给出特征数据值,反映出新疆750kV线路地形和风况的全局时空特点,为针对性风害防治以及有效提高经济指标提供关键依据。Xinjiang 750kV UHV transmission lines is an important part of the advantageous resource transformation strategy in Xinjiang.In the energy strategic layout,it can help realize power mutual supply between North and South of Xinjiang,between hydropower and photovoltaic power.Meanwhile it can improve power supply reliability and the capacities of mutual supply and accepting the new energy capacity.Xinjiang 750kV UHV transmission lines covers large regions.The regions'terrain along the lines is complex.The strong wind is the meteorological characteristic and one of major external factors leading to lines'faults.The operation and maintenance of 750kV lines need mastering the spatial and temporal characteristics,so as to carry out the special treatment.Based on the terrain DEM data and the data of wind speed and direction from 2011to 2015,this paper analyzes data of the terrain and wind conditions along 750kV UHV Transmission Lines in Xinjiang,such as poles'altitude,slope,aspect,annual average wind strength,over 6level wind and so on.The conclusions give the concrete values,which reflect the global temporal and spatial characteristic of Xinjiang 750kV UHV transmission lines,and provides the key basis for the special prevention and treatment of wind damage and improving the commercial efficiency of design and build.
