摘要
在小电流接地系统中,现有单相接地故障选线装置适应性较差、正确率不高,为此,提出了基于模糊综合决策的多重复和判据方案。由MATLAB仿真实验证明,该方案能有效弥补单一判据的不足,不受小电流接地系统结构及运行方式变化的影响,完全实现单相接地故障的正确选线。
The existing fault line selection facilities for single phase grounding in low current grounding system is slow in adaptability and low in accuracy. Therefore the authors suggest solution with multi repetitive and compositive criterions based on fuzzy eompositive decision, which has been proved by MATLAB simulation test, a good remedy for the single criterion in old solution. Under this solution the line hitting exactly fight in single phase grounding fault can be realized, without influence from the configuration and operation variation of the low current grounding system.
