您要查找的是不是:
- Their common shortcoming is that they act blindly entirely before reclosing and can not distinguish instantaneous fault from permanent fault. 它们共同的缺点就是在重合闸之前,完全是盲目的动作,无法区分线路发生的是瞬时性故障还是永久性故障。
- The switches are sequential tripped at optimal trip time and shut down reclose for permanent fault. 永久性故障时,在最佳跳闸时刻分相跳开非故障相,闭锁重合闸。
- Reclosing at optimal time can largely improve system stability even if reclosing on permanent fault. 即使是重合于永久性故障,只要在最佳时刻重合闸同样可以显著改善系统的稳定性。
- The reason that the system stability can be improved when reclosing at sometimes at the permanent fault is analyzed. 实际系统的仿真表明,本文计算出的最佳时刻重合,重合成功后系统的振荡明显小于其它时刻重合。
- A novel method of identifying permanent fault for single-phase adaptive reclosure in transmission lines with shunt reactors is proposed. 针对带并联电抗器的超高压输电线路,提出一种单相自适应重合闸永久性故障识别的新方法。
- Single-phase adaptive auto-reclose technology possesses many advantages compared with traditional reclosing technology,as the important measure of avoiding permanent fault. 自适应重合闸技术作为避免重合于永久性故障的重要措施,具有很多传统重合闸技术所不具有的优势。
- For phase-to-phase fault, it trips three phases and recloses three phases (checking synchronization and no-votage);when reclosing on permanent fault, it trips three phases. 使开关相间故障跳三相,重合三相(检定同期或无压),重合于永久性故障跳三相。
- When a permanent fault occurs on a distribution feeder, the circuit breaker will trip under the control of protection and subsequently the section switches will also trip for loosing voltage. 当馈线发生永久性故障时,出线保护跳闸,随后各分段开关失压分闸。
- The conditions that fast reclosing must satisfy is analyzed.When the kinds of fault can be identified correctly,the reclosing time can be set respectively for instantaneous and permanent fault. 分析了实际系统中采用快速重合闸时应满足的系统条件,指出在能够判别瞬时与永久故障时合闸时间的整定应按最大送电方式分别整定计算。
