Abstract
This work presents a Wound Field Synchronous Generators (WFSG) terminal voltage control system modeling and design. The approach proposes a simple and robust static excitation system using a Buck converter powered from an external source. The calculation of the RMS value of the terminal voltages for control system feedback is replaced by obtaining the vd component of the three-phase voltages. Experimental results prove the maintenance of terminal voltages within the established limits.
