| Résumé: | This research work presents an enhancement in the positive offset mho element that may be used in the loss of excitation (LOE) protection scheme of synchronous generator associated with a static synchronous compensator (STATCOM) in transmission line. This enhanced element of the protection scheme is based on recalculating the impedance at the relay location by eliminating the injected STATCOM current measured by phasor measurement unit (PMU). Under total or partial loss of excitation condition, the simulation results show that the new developed method improves the operation of the positive offset LOE protection by reducing the delay time that may be due to the presence of STATCOM. |
