Experimental Evaluation of the Laboratory Setup with Synchronous Generator with Rotating Diode Rectifier

Synchronous generators are an essential part of power systems, and the number of generators is increasing due to the growing electricity demand. Synchronous generators can operate synchronously with the grid or independently in island mode. In both cases, the generator rotation (speed or torque) and the generator excitation current must be controlled. This paper provides an overview of the laboratory setup, which consists of a brushless synchronous generator and an induction motor driven by a frequency converter. A rotating diode rectifier excites the synchronous generator, and a chopper controls the excitation current. The laboratory setup offers many possible applications in research and teaching. The laboratory setup is therefore evaluated, and the experimental results are presented in this paper.
