摘　　要：按照传统标准设计的输电线路规划存在效率低和资本浪费等问题。经济研究表明,采用优化设计和科学成本管理方法的输电线路建设对于节省资本投资具有重要意义。因此,从输电线路扩建规划方面进行了探讨研究,以帮助在输电线路建设和运营方面做出更明智的决策。首先,通过综述国内外的研究论文,概述了输电线路规划的基础理论,系统梳理了输电线路规划的方法,包括确定性方法、启发式方法、元启发式方法等,分析了各种方法的优缺点;然后,在经济评估方面考虑线路建设、运行、维护等多个阶段的费用,提出了寿命周期成本分析,更全面地评估输电线路规划方案的经济性。In the past,transmission line planning based on standard designs suffered from inefficiency and capital wastage.Economic studies show that employing optimal design and scientific cost management for transmission line construction is crucial for saving capital investment.So the review of research efforts in transmission expansion planning is given to facilitate more informed decision-making regarding the construction and operation of transmission lines.By surveying domestic and international research articles,the fundamental theories of transmission line planning are outlined.The methods for transmission line planning,including deterministic,heuristic and metaheuristic approaches,are systematically delineated and their respective strengths and weaknesses are analyzed.Then,for economic evaluation,a life cycle cost analysis is proposed to account for expenses across multiple phases such as line construction,operation and maintenance,which can more comprehensively evaluate the cost-effectiveness of any given transmission planning scheme.
