Criteria Setting of Earthfault Relay Coordination for Bhutan Substation
Earthfault relays (51N) operate based on zero sequence fault current. Since most of the faults that occur on the power system are the earthfault, therefore, coo
This thesis proposes a review of coordination of distance relays for transmission lines of a real network in Bhutan for study. I would like to extend my profound gratitude to my supervisor Dr. Le, for...

The document outlines the criteria for Overcurrent Relay Coordination in Bhutan''s substations interconnected to the Indian Grid, addressing issues of reliability and security.
Overcurrent and ground fault relay coordination have been studied for a pilot 132/33/11 kV Substation in Bhutan. The calculated settings as well as the existing settings have been simulated and the critical
Non directional Overcurrent relays (51) are widely used for overcurrent protections in substations. The criteria settings for the relay coordination play a vital role in reliable fault discrimination.
In this project, case studies shall be carried out on how the Bhutan power system could effectively island from Indian grid connection when there are disturbances
All the numerical protection relays installed for transmission lines, transformers, bus bars and outgoing feeders with disturbance recorder function shall be set as below:
