| Abstract: |
| A locating algorithm based on faulty section identification is presented. According to the current information transmitted from FTUs(Feeder Terminal Units),the unitary area load vectors of distribution network is deduced,and the faulty section is detected effectively by searching for the over-heated areas. The principle of the algorithm is explained and a deduction example is offered,which shows it effective. It also works for branch-end faults and parallel multi-faults. |
