| 摘 要： | 特高压交流试验示范工程中开关偷跳或特高压解列装置动作引起特高压线路开关三相跳闸时,特高压线路将空载运行,线路两侧系统电压大幅上升,不利于设备安全及系统稳定运行。文章在分析了稳态过电压产生的原因后提出了稳态过电压的控制策略,即由单独装设的稳态过电压装置自动处理,运用在特高压交流试验示范工程中,实现了保护一次设备及保证系统安全稳定运行的目的。

| Abstract: | When trip-out of three-phase transmission line occurs in 1000 kV pilot demonstration project due to circuit breaker tripped without operation of protection or the action of UHVAC sectionalizing device,the 1000kV transmission line will be in the state of no-load operation.On this occasion,system voltage at both sides of the transmission line will be considerably arisen and it goes against equipment safety and stable operation of power system.After analyzing the cause of steady-state overvoltage,a control str... |
