The type of excitation systems mainly used for synchronous generators are the static excitation system and the blushless excitation system. The increase of single-unit capacity is remarkable nowadays. As single-unit capacity increases, its influence on the grid system makes a larger contribution in the case of a network fault. Therefore, it is desired to improve the accuracy of the equivalent circuit model for simulating the transient phenomena, including the excitation system. There have been many general characteristic explanations with two excitation systems. However there is no report has been published using actual model systems. The authors reported response and stability characteristics in 4-pole synchronous generator excitation system with actual generator model.
