Computer model analysis of dynamic performances of the excitation control system when the load angle limiter is active

A load angle limiter was implemented as an additional function in the existing excitation system to enable operation of synchronous generator entire P-Q diagram according recommendation manufacturer unit B2 "Nikola Tesla B" TPP. The analysis dynamic performance presented this paper consists determining time responses and frequency characteristics control when is active, based on which values indexes were obtained. In addition, also provides a brief description implementation limiter, well computer models used analysis.
