【摘要】 针对国家电网典型设计方案220-B-1中进出线及母联间隔采用GIS的220kV HGIS变电站,通过选用紧凑型HGIS设备、采用HGIS设备双列布置、增减巡检通道设置、采用进出线构架与母线构架联合构架、压缩管母及出线间隔之间的距离等措施进行了尺寸优化。使用ATP-EMTP搭建电磁暂态模型,对优化设计后的220kV变电站雷电入侵下的设备过电压水平进行仿真分析。仿真结果表明,文中采用的优化设计方案,能够满足雷击变电站条件下站内各重要设备的绝缘要求,具有较好的技术性和经济性。更多还原

【Abstract】 In this paper,the dimension of 220 kV HGIS substation that was designed based on typical design scheme220-B-1of State Grid adopting the GIS for bus-link interval,incoming and outgoing lines was optimized by choosing compact HGIS equipment,being arranged in double columns for HGIS,increasing or decreasing the inspection channel settings,adopting combined frames of the frames of the line and the bus frames,compressing the distance between buses,outgoing line intervals.The electromagnetic transient model was built using EMTP-ATP to carry out the simulation analysis of equipment’s overvoltage level in the case that the substation was under lightening attack.Simulation results show that the optimization design scheme which had technical and economical advantages could meet the insulation requirements for the important equipment in the station under the condition of lightning attack.更多还原
