| 摘 要： | 传统的比较零序电流故障选线方法,不便在配电自动化现场终端单元(FTU)上实现。本文提出了几种基于FTU仅需就地采集电压电流量的接地保护方法,并对各种接地保护方法进行信息融合处理,提出了故障线路模糊识别技术。EMTP仿真和动模实验结果表明该接地保护具有很高的精度和鲁棒性,完全能够满足配电自动化要求。 |

| Abstract: | Traditional fault detection schemes based on zero sequence currents are difficult to satisfy the requirement of distribution automation (DA). In order to improve it, some novel techniques for ground-fault feeder detection are presented in this paper, and they are implemented with currents and voltages tested by feeder terminal unit (FTU). With information fusion techniques, faulty feeder is identifi ed by fuzzy analysis. The protection schemes have been tested by EMTP simulation. A prototype has been developed and tested in a dynamic power system. Results show that these proposed protection schemes have high sensitivity and robustness. |
