Trouble shooting of generator differential relay operation using digital simulators Conference Paper uri icon

abstract

  • This paper gives an example of the protective relay operation evaluation using digital simulators. A generator differential relay protecting a 1500 MVA generator was found to be tripping under in-rush current conditions caused by energizing an adjacent power transformer. A digital simulator was used to recreate the conditions using Electromagnetic Transient Program (EMTP) simulation. The waveforms generated by the simulator were applied to trouble shoot the relay operation. It was also used to test two more relays to finally select the one that will not be sensitive to the inrush conditions.
