| 摘 要： | 采用PSCAD/EMTDC软件计算分析了江苏抽水蓄能电站500 kV GIS变电站在主变、出线操作时的特快速暂态过电压(VFTO),并以1台典型的500 kV主变为例,分析多种操作情况下特快速暂态过电压对主变的影响.结果表明,由于连接各台主变与GIS之间的电缆比较长(至少200 m),传递到各台主变上的VFTO幅值和陡度并不高,对其主绝缘影响不大,也不会直接造成变压器匝间绝缘的击穿. |
| 关 键 词： | 抽水蓄能电站 GIS变电站 特快速暂态过电压 匝间绝缘 |

| Abstract: | With the help of PSCAD/EMTDC software,the very fast transient overvoltage(VFTO) which occurs during operation on main transformers and outgoing lines in the 500 kV GIS substation for Jiangsu Pumped-Storage Power Station is calculated and analyzed,and a typical 500 kV main transformer is taken as an example to describe the effects of VFTO on main transformers during various operation.The results show that since the cables connecting the main transformer and the GIS are long(at least 200 m),the amplitude and gradient of the VFTO which transmits to every main transformer is not high,and effects of the VFTO on transformers are negligible. |
| Keywords: | pumped-storage power station GIS substation very fast transient overvoltage(VFTO) interturn insulation |
