摘 要
当今智能电网建设面临项目建设周期加长和专业融合迫切两大亟待解决的问题,因此,立足于智能变电站的总体高度重新定位站内整体功能需求和设备配置, 实现技术模式与建设模式的转变是电网建设顺应时代发展的必由之路。
基于这样的视角,本课题打破了以设备供应商为主导的传统局限,针对智能变电站关键技术领域,依托国网试点工程建设,运用“设计引领设备制造”的全新的研究思路,重点完成了以下几方面的工作:
,创新智能一次设备设计和制造模式; 提出二次总集成的招标采购模式,实现了工程建设模式的创新。
,提出二次系统模块化配置原则及典型划分方案,并结合当前集成制造业的发展,将集成优化设计技术及模块化设计技术相结合应用于预制式二次组合设备舱,依托黄山浩村IlOkV变电站工程进行全站二次设各的最优化集成配置,提出llOkV户外AIS变电站的二次系统典型模块化配置方案。
,并针对典型问隔划分,作出全站预制光缆的统计;针对二次标准接口做出航空插头的数量及插芯数目统计,用以规范“即插即用”技术的标准化设计,对后续智能变电站的建设具有一定的参考价值。
、小型化环保设备及模块化建设策略在智能变
电站优化设计中的应用实践进行了成果提炼、总结与展望。
新一代智能变电站采用一体化设计、一体化供货、一体化调试模式,实现“占地少、造价省、可靠性高”的目标,打造了“系统高度集成、结构布局合理、装备先进适用、经济环保节能、支撑调控一体”的技术新高度。

Abstract
Nowadays,the construction of smart西d iS faced with two problems which are urgent to be solved,oile is the lengthened construction period,and the other is professional ,it is of great necessity to reposition the station overall
functional requirements and equipment configuration based on overall sight of the Smart
Substation to realize the transfo姐ation of P皿d technology mode and construction mode,
as the society is under great development.
Based on this perspective,the conventionN limits of the equipment-supplier-leading mode are broken in this paper,and the brand-new mode‘‘design-leading equipment manufacturing'’is proposed,which is designed for the key techniques in the field of
intelligent is relying on the pilot projects for
following several aspects of work are focused:
concept of an intelligent module’S integration with the primary equipment in place and a design and manufacturing mode of the intelligent primary equipment are
an integrated secondary equipment bidding and procurement mode is put forward,which realizes the innovation of the project construction mode.
