Faulted Line selection Method for electric power system

Research Methodology

1. An Automated Faulted Line Selection Method for Electric Power Distribution Systems Based on Multisource Information Authors: Kongming Sun, Qing Chen and Zhanjun Gao IEEE Transaction on Power Delivery August, 2016 Presented By: Muhammad Azeem Reg No: SP18-REE-011

2. Problem Statement These days it is an important issue to keep the reliability of power supply in transmission and distribution. Power distribution network is much larger then power transmission network Almost 80% faults occur on distribution system It is important to have a system that is accurate and fast in detection of fault in the system Conventionally fault was identified and localized by visual inspection.

3. Previously Proposed Methods Travelling wave based methods Impedance based fault location method Voltage sag based method Knowledge based method

4. Proposed Solution for MV Distribution System

5. Case of Fault at O ne Point

6. Case of Multiple Fault Points

7. Case of Fault at DGs

8. Case of Information Lost at a Point

9. Case of Multiple Information Lost Point

10. Fault Detection at LV Side

11. FLOW CHART

12. Conclusion Algorithm for automated fault line selection method for MV distribution was proposed using adjacency list and status of FID In case of lost of information a method for reverse iterative method lost information was recovered Successfully implemented for single and multiple fault points Algorithm for automated fault in LV distribution system using feedback from power meters
