| 摘 要： | 小电流接地系统单相接地故障选线方法目前已有很多,但每种方法都有针对性和局限性,故采用单一选线方法精度较低.为解决这一问题,根据不同小电流接地系统的电气特征,选择出具有优势互补的三种选线方案作为多重判据智能融合的依据.考虑到故障选线中存在各种不确定信息,构造了基于各选线方案的故障测度和对于正确选线的可信度.在此基础上,采... |

| Abstract: | Selecting line methods of single-phase-to-earth fault in the non-utility grounded system are already many,but each existing methods has relevance and limitations,so a single line selection method less accurate.In order to solve this problem,a complementary three selecting method that serve as the criterions for the intelligent integration of multiple criteria was proposed in the paper,which is based on different electrical characteristics of different non-utility grounded system.Considering uncertain inform... |
