【摘要】：作为坚强智能电网的重要支撑和基础,智能变电站是整个电网建设的重要组成部分。新一代智能变电站以“系统高度集中、结构布局合理、装备先进适用、经济节能环保、支撑调控一体”为目标,可以解决智能变电站安装复杂、建设周期长、运营维护困难、成本高等问题,是未来智能变电站及智能电网发展的方向。因此,新一代智能变电站的建设具有非常重要的理论和现实意义。本文对唐山步步川110k V新一代变电站的设计和应用进行了研究。首先完成了需求分析和总体规划,给出整体设计方案及系统方案,在满足通用设计规范、符合新一代智能站要求的基础上,结合本地区运行条件,通过选择新型智能设备使变电站整体智能化水平提高。然后设计了唐山步步川110k V变电站一次系统并进行了设备选型。结合设备发展的现状,本工程GIS内进出线间隔采用电子式电流电压组合式互感器;110kV电压等级及35kV和10kV主变进线间隔采用电子式互感器+智能组件的方式实现一次设备的智能化。最后设计了唐山步步川110k V变电站二次系统并进行了智能化二次设备选型,将站内公用、110k V及主变间隔的间隔层设备布置于II型预制舱内,舱内设备采用前接线前显示装置,实现了预制舱式布置的设计思路。采用预制光缆技术,实现了一次设备与二次设备间光缆、电缆的标准化连接,提高了二次线缆施工的整洁和美观度,并大大缩短了施工周期。目前该变电站已经进入调试阶段,由于依据国网公司最新智能变电站设计规范要求进行设计,并充分考虑当地自然环境对设备布置的影响,在满足智能站设计要求的基础上合理布局,节省了占地,减少了建设投资。本工程所在地区为高污秽等级地区,对污染严重地区有一定的借鉴意义,为新一代智能站的设计提供了参考,能够为以后智能变电站的建设起到示范作用。
[Abstract]:As an important support and foundation of a strong smart grid, smart substation is an important part of the whole power grid construction. The aim of the new generation intelligent substation is "highly centralized system, reasonable structural layout, advanced and applicable equipment, economic, energy saving and environmental protection, support and control", which can solve the complex installation of intelligent substation, long construction period, difficult operation and maintenance, The problem of high cost is the development direction of smart substation and smart grid in the future. Therefore, the construction of new generation intelligent substation has very important theoretical and practical significance. In this paper, the design and application of the new generation substation of 110 kV in Tangshan are studied. First of all, the requirements analysis and overall planning are completed, and the overall design scheme and system scheme are given. On the basis of meeting the general design specifications and the requirements of the new generation intelligent station, combined with the operation conditions of the local area, By selecting new intelligent equipment, the overall intelligence level of substation is improved. Then the system of 110 kV substation in Tangshan step by step was designed and the equipment selection was carried out. Combined with the present situation of equipment development, electronic current voltage combined transformer 110kV voltage grade and 35kV and 10kV main transformer intelligent module are used to realize the intelligence of primary equipment in GIS. Finally, the secondary system of 110kV substation in Tangshan step by step is designed and the intelligent secondary equipment is selected. The interlayer equipment of common 110kV and main transformer interval in the station is arranged in the type II prefabricated cabin. The equipment in the cabin adopts the display device before the front wiring. The design idea of prefabricated cabin layout is realized. By using the technology of prefabricated optical cable, the standard connection of optical cable and cable between primary equipment and secondary equipment is realized, which improves the neatness and beauty of the construction of secondary cable, and greatly shortens the construction period. At present, the substation has entered the commissioning stage. Due to the design requirements of the latest intelligent substation design code of China National Network Company, and fully considering the impact of local natural environment on the equipment layout, On the basis of satisfying the design requirements of intelligent station, the reasonable layout can save the land and reduce the construction investment. The area where the project is located is a high pollution grade area, which has certain reference significance for the seriously polluted area, provides a reference for the design of the new generation intelligent station, and can play an exemplary role in the construction of the intelligent substation in the future.
