temporary fault

A novel approach of distinguishing between temporary and permanent fault in single pole autoreclosing based on fault location is proposed.

该文提出一种基于故障测距的单相自动重合闸永久故障电压自适应补偿判据。

The similarities of the amplitudes and phases between the voltage of opened phase conductor and the sum voltage of two healthy phases are all included in the criterion so that the correlation coefficient of a temporary fault is larger than that of a permanent one.

该判据综合考虑了断开相计算电压与两健全相电压和的幅值与相位的相似性，使瞬时性故障时的相关系数大于永久性故障时的相关系数。

Selective unit commitment is an temporary solution for fault current reduction and is widely used in power systems under the circumstance as instruments examination or test run.

有选择的停机是短期内限制短路电流的临时解决方案，在电力系统设备临时检修或试运行等情况下得到了应用。

In this paper, firstly, based on the analysis of the models of the primary arc and the secondary arc under the temporary single-pole fault, the waveform of the voltage of faulty phase under the different type of fault is simulated by ATP-EMTP.

本文首先分析了单相瞬时性故障情况下的一次电弧和二次电弧模型，利用ATP-EMTP仿真软件仿真得到了不同故障性质情况下的故障相端电压波形；

The results show that recovery voltage of temporary fault contains the components of power frequency component and free component, while the recovery voltage of permanent fault only contains power frequency component.

研究表明单相瞬时性故障时的恢复电压由自由分量与工频分量叠加而成，而永久性故障时的恢复电压中只包含工频分量。

Additionally, routing reconfigurability can solve the problem of routing failure caused by the temporary or perpetual link fault.

另外，路由重构可解决链路短时或长时失效带来的选路失败问题。

This criterion uses the fault location result to get the fault point voltage and take the fault point voltage in theory as the setting value to distinguish the permanent fault from temporary fault.

该判据以故障点瞬时故障电压理论值为定值，由故障测距结果求出故障点实际电压，当故障点实际电压小于定值时为永久性故障，反之为瞬时性故障；
