摘要
随着我国电力系统的发展，传统上的常规截面输电线路已愈来愈难以满足要求。本文通过妈湾电厂接入系统的工程实例，分析了新形势下的负荷增长需求、技术经济指标及标准的变化，有限土地、环境资源对电网建设的制约，认为采用大截面输电线路应成为电网特别是城市电网建设发展的趋势。
With the development of national economy, the transmitting capability of the ordinary transmission lineswith a cross-sectiona less than 2×300mm2 can hardly meetthe need of continuing increase of load. Through the engineering practice of Mawan project,the author points outthat the power network construction is restricted by powerload,limited resources of land and environment, technicaleconomics indices and technical standards, therefore in highcapacity power systems, especially in urban systems, to usetransmission line with super-cross sectional area is a certaintrend.
