Popis:	This paper analyses the influence of the operation of the automatic voltage regulator and the stator maximum current limiter in the excitation system on the operation of under-impedance generator protection, with the focus on zone 2 of the protection function. The paper analyses the response of the automatic voltage regulator to a given disturbance in the transmission network and observes its influence on the trajectory of the operating point measured by the under-impedance generator protection. Based on the simulation results, the adequacy of the selected under-impedance protection settings was evaluated. Network modelling and analysis were performed in the DlgSILENT PowerFactory software package.
