单相自适应重合闸研究综述

A Review of Single-phase Adaptive Autorecloser

为了实现瞬时性故障时可靠重合,永久性故障时可靠不重合的目标,对单相自适应重合闸的研究情况进行了分析和总结。首先根据瞬时性故障过程三个阶段不同特征以及线路是否带并联电抗器进行分类,对每一类原理进行了梳理。然后对各类判据的特点及存在的问题进行了分析。研究后认为,基于恢复电压阶段的判据虽无法判断熄弧时刻,但原理简单,易于实用化,是现阶段实用化研究的重点,而基于二次电弧阶段的判据虽然能够判断出熄弧时刻,但是原理复杂,对硬件要求高,是未来研究的重点。

This paper discusses and summarizes the study status of the single-phase adaptive autorecloser,in order to reach the goal that the device should reliably reelose in transient faults and not reclose in permanent faults. These methods are classified according to the three stages in transient faults and the equipment situation of shunt reactors. Each kind of theory is presented and analyzed according to its features and problems. The research indicates ： though disable to determine the quenching of are, criterions based on the recovery voltage stage are simple and have higher practicability, and they should be the research priority at present ; criterions based on the secondary arc stage arc able to determine the quenching of arc but have complex theory and high requirement of hardware equipment, and they will be the focus of future study.
