| 摘 要： | 针对现有利用暂态量的选线方法在电压过零附近时故障灵敏度低的问题,通过把消弧线圈支路作为一条健全线路,利用其暂态能量与其他所有线路暂态能量之和为零的关系,提出了一种基于消弧线圈暂态能量的谐振接地电网故障选线新方法.此选线方法无需判断故障合闸角,也无需整定,不仅能克服在电压过零附近故障选线灵敏度低的缺点,还能适应消弧线圈接地系统各种变化,具有很强的抗干扰能力及自适应性.大量的数字仿真结果表明,该方法有效、可靠. |
| 关 键 词： | 消弧线圈接地系统 单相接地故障 消弧线圈 暂态能量 |

| Abstract: | In order to overcome low sensitivity of the protection based on transient components when the faulty voltage passes zero, regarding arc suppression coill branch as a healthy feeder line, using the relation of its transient energy and all feeders of transient energy amounting to zero, this paper presents an improved fault line selection method in arc suppression coils system using transient energy. This method has no requirements of detection fault close angle and pre setting, has a good anti interference ability and adaptability to various faults occurred in the systems with arc suppression coils. Large amount of digital simulation results show that the proposed method is effective and reliable. |
| Keywords: | resonance grounding system single phase-to-earth fault arc suppression coil transient energy |
