Operation time of primary relays in IEEE 30 bus network

This is an excel file to compute Operation Time (OT) of primary relays in IEEE 30 bus network with 2 DGs. This file is provided to make a fair comparison between methods.
It is supposed that the relays have standard inverse characteristic curve. Link to the reference where the fault currents were taken is provided. To compute the OTs, it is required to insert PMS and TMS of relays in corresponding columns. OT of relays are computed in the column named OT (s). OTs of 3 published papers were computed. The links to the references were provided as well. At the bottom of columns, sum of relays OT was computed.
