This paper presents a method for selecting parameters and analyzing the dynamic characteristics of a under-excitation excitation limiter using a computer model. The parameters are determined using the pole cancellation method for the worst-case operating regime from the perspective of the under-excitation limiter to ensure stability in all operating regimes. The analysis of the dynamic characteristics presented in the paper first obtained the time responses and frequency characteristics of the excitation control system when the limiter is active. Based on these, the values of dynamic performance indicies that indicate the quality of regulation are determined. The paper also provides a brief description of the implementation of the limiter and the computer models used in the analysis.
