Abstract
The paper presents a microprocessor closed-loop-like control scheme for an automatic voltage regulation ( AVR ) and reactive power compensation at the terminals of a dc-motor driven synchronous generator. The experimental set-up consists of the electrical-power generating unit, a single-phase thyristor-type excitation system, the microprocessor application trainer MAT-385 of Feedback and necessary prephirals. Supervisory programmed algorithms have been developed and the whole control system is put in working order for test. Laboratory experimental investigations showed satisfactory performance. The terminal voltage has been maintained within the standard limits for both and sudden load fluctuations. Additional control objectives, such as frequency control or generator protection can be integrated in the supervisory programs of the dedicated microprocessor.
