摘要
针对500 kV HGIS新型设备不断涌现,以往建立的变电站雷电侵入波计算模型需要改进的问题,采用HGIS新型设备的某500kV变电站,分析设备生产厂家提供的HGIS结构参数和试验参数,建立其雷电过电压计算模型,并结合以往采用常规设备变电站的设计经验,优化变电站雷电过电压计算方法,采用国际通用的EMTP电磁暂态仿真计算程序,对500kV HGIS变电站的雷电侵入波作了较为深入的计算分析和研究,提出了该工程针对雷电过电压500kV母线侧可不加装避雷器,出线侧需加装避雷器的配置方案,该研究可供变电站雷电过电压建模仿真计算参考。
With the development of 500kV transmission and distribution engineering project, project demonstration, experiment and research of 500kV substation are done in-depth. The simulation of protection of lightning intruding surge is the important content in 500kV substation, which is researched in-depth by many electric power experiment research institutes and power design institutes. But aimed the new equipment that is Hybrid Gas Insulated Switchgear（HGIS） in some 500kV substations, the simulation of protection of lightning intruding surge is researched by few electric power experiment research institutes and power design institutes. The model needs to be improved. In the text structure and test parameters of HGIS which are afforded by HGIS manufacturer are analyzed in-depth. Aimed thunder over-voltage in the 500kV HGIS substation, models of HGIS are combined , calculating method of thunder over-voltage is optimized, and the selection of the main initial condition of lightning intruding surge is researched in-depth. Aimed several operations of an outgoing loop and a transformer in the 500kV HGIS substation, protection of lightning intruding surge is simulated by Electromagnetic Transient Program （EMTP）. Finally the scheme of arrester in the 500kV HGIS substation is brought forward. The 500kV bus bar doesn＇t need to install arrestor and the outlet line needs to install arrestor. The research results have some guidance significance to simulate thunder over-voltage in 500kV substation in future.
