摘要
针对沙戈荒大基地风电项目的特殊气候与地质条件,系统进行了集电线路的选型与优化研究.首先,对集电线路的回路数量与路径进行了分析,根据负荷需求明确了回路划分原则;其次,依据载流量需求确定了导线截面,选定了适宜的杆塔型式与构造;再次,分析了地质条件,优化了基础型式以降低基础成本并提升稳定性;最后,研究了防风拉线金具的设计与固沙方案的实施.项目预测集电线路优化将实现成本节约并提高运行可靠性,为风电项目提供经济、有效的集电线路设计方案.
Abstract
This paper conducts a systematic study of the selection and optimization of current collection lines in view of the special climate and geological conditions of wind power projects in the general desert-gobi-huangriness base.First,it analyzes the number and path of circuits in the current collection line,and clarifies the division principle of circuits based on load demand.Then,it determines the cross-section of conductors based on the requirements of the current carrying capacity,and selects suitable the type and structure of poles and towers.Again,it analyzes geological conditions and optimizes foundation forms to reduce foundation costs and improve stability.Finally,it studies the design of windproof wire fittings and the implementation of sand fixation schemes.The project predicts that the optimization of current collection lines will save costs and improve operational reliability,which provides an economical and effective design solution of current collection lines for wind power projects.
