| 摘 要： | 根据国内外已有的研究成果，并结合PSCAD程序仿真分析，对特高压系统操作过电压及其限制措施进行系统的研究与讨论。 研究表明，特高压操作过电压应主要考虑接地故障、合闸与分闸过电压，其中接地故障过电压相对较低，通常使用线路两端避雷器即可将其限制在允许范围内；合闸过电压可采用合闸电阻或配置多组避雷器两种措施来加以限制，但前者存在故障、损坏等问题，而后者已在超高压系统实际运行中得到了验证；分闸过电压可使用分闸电阻或配置多组避雷器来限制，但考虑到前者不足之处较为突出，我国特高压线路倾向于不使用分闸电阻。

| Abstract: | Based on both domestic and foreign existing study results,and combining PSCAD simulation analysis,this paper studies and discusses the switching over-voltage in UHVAC and its restrictions.Researches show that main attention should be paid on the ground fault,closing and opening over-voltage in UHVAC switching over-voltage.Ground fault over-voltage is relatively lower and can be restricted to allowance by installing arresters at the both ends of line.Closing over-voltage can be suppressed by adopting closing... |
