Abstract

As a follow up of one of the recommendations of Enquiry Committee headed by Chairman, CEA on grid disturbances that took place in Indian grid on 30th and 31st July 2012, Ministry of Power constituted a ‘Task Force on Power System Analysis under Contingencies'in December 2012. The Terms of Reference of Task Force broadly cover analysis of the network behaviour under normal conditions and contingencies, review of the philosophy of operation of protection relays, review of islanding schemes and technological options to improve the performance of the grid.

Apart from the main Task Force two more sub-committees were constituted. One committee for system studies for July- September 2013 conditions and another committee for examining philosophy of relay and protection coordination.

One of the tasks assigned to the protection sub-committee was to prepare procedure for protection audit. The details given below are part of the work done by this Protection Sub- committee.
