摘要
随着电力需求量持续增长,220 kV变电站采用双母双分段主接线来提高供电可靠性。在一些停电影响小或负荷不重要的场合,为了节约投资成本,一般都会采用隔离开关进行分段。以某型252 kV GIS为例,提出了一种GIS双母线隔离分段间隔布置结构优化设计型式,从设备尺寸参数、占地面积、元件数量、气体消耗量方面与原布置结构进行经济对比,结果表明优化后布置结构紧凑、占地面积小、元件数量少、气体消耗量少、制造成本和施工成本显著降低,可为其他电压等级的GIS双母线隔离分段间隔布置设计优化提供参考。
With the continuous growth of power demand,220 kV substation adopts double bus and double section main connection to improve power supply reliability.In some occasions where the impact of power outage is small or the load is not important,in order to save investment costs,isolation switches are generally used for segmentation.Taking a certain type of 252 kV GIS as an example,an optimized design type of GIS double-bus-bar isolation segmental spacing arrangement structure is proposed.From the aspects of equipment size parameters,floor space,number of components,and gas consumption,an economic comparison is made with the original layout structure.The results show that the optimized layout has advantages of compact structure,small floor area,less components,less gas consumption,lower manufacturing cost and construction cost,which can provide reference for the design optimization of GIS double bus isolation section spacing layout of other voltage levels.
