Sažetak
Loss-of-excitation protection of a large synchronous generator was tested at the site by injecting simulated generator current and voltage signals obtained from the EMTP simulation for various fault scenarios. The protection operates on directional current principle with overcurrent / undervoltage control. In order to achieve proper coordination of the protection with the unit's underexcitation limiter a new setting of the protection was proposed. By recording the protection response during tests its correct operation has been proved. Finally, the validity of the new setting has been assessed by checking the protection operating characteristic during primary field tests.
