| Abstract: |
| Power distribution systems are profoundly inclined to disturbances like untimely switching of breakers & relays,
sympathetic tripping, and uncertainties regarding fault location. Thus, system stability and reliability are greatly
affected. In this way, situational awareness and system integrity are the crucial factors in developing power system
security, as it empowers successful decision making & timely reaction by the operators to any disturbance and also
maintaining continuity of power supply. This paper focuses on the enhancement of situational awareness by fault
location through fault passage indicators (FPI) to improve nominal impedance-based methods in distribution
networks. Also, the proposed method is validated by comparing it with Intelligent Electronic Device (IED) based
fault location method. Further, simultaneous reconfiguration of the system is incorporated to maintain the
continuity of supply. The analysis has been tested on IEEE 33 bus distribution system. |
