摘要
基于模块化的智能变电站设计可有效避免现场安装的多种问题,提高变电站的建设效率。本文针对基于模块化的智能变电站设计发展趋势和面临问题开展研究,首先对智能变电站通用设计的应用需求进行调研分析,并结合新技术和新设备,给出了基于模块化建设的智能变电站一次和二次功能模块组成方案。其次从新型线路和开关技术、电能质量和定制电力技术,以及系统保护与故障监测技术等三个方面,对相关技术和典型设备进行讨论,分析了其对变电站设计和施工的影响。最后结合已有的模块化变电站建设情况,分析了模块化智能变电站设计和建设可能存在的问题,并给出了相应建议。
The design of a modular intelligent substation can effectively avoid some problems in field installation and im prove the construction efficiency of the substation.In this paper,the development trend and problems in modular intelli gent substation design are studied.Firstly,the application requirements for the common design of intelligent substation are investigated and analyzed,and the composition scheme of the primary and secondary function modules of modular intelligent substation are given by combining the new technology and new equipment.Secondly,the related technology and typical equipment are discussed from three aspects,i.e.,new line and switching technology,power quality and cus tomized power technology,as well as system protection and fault monitoring technology,and the influences on the de sign and construction of substation are analyzed.Finally,combined with the condition of the existing modular substa tion construction,some possible problems in the design and construction of modular intelligent substation are put for ward,and the corresponding suggestions are also given.
