| 摘 要： | 针对小电流接地系统中,现有单相接地故障选线判据适应性较差、正确率不高的现状,提出基于模糊综合决策的多重复合判据方案,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 Study on Fault Line Selection in Distribution Networks based on Fuzzy Principle |
| |
| Abstract: | A new scheme of multi-criterion about earth fault diagnosis in the networks with floating neutral based on fuzzy principle is proposed. It has been validated by MATLAB, the simulation results indicate that this scheme can overc ome the disadvantages of each individual criterion efficiently, which can select the fault line accurately independent of the configuration and operating mode o f the power distribution. |
