Research of AC Excited Generator Excitation Control System Based on Full Fuzzy Controller

AC excited generator (ACEG) has more excellent characteristics than conventional synchronous and asynchronous generators, and it is widely developed in variable speed constant frequency (VSCF) generation area such as wind power generation and pumped storage power generation. Based on intelligent fuzzy control technology with good adaptive and robust capability, a new excitation control strategy for ACEG without accurate generator mathematical model is proposed in this paper. Full fuzzy excitation control model is established and analyzed in detail. An ACEG experiment platform based on dual PWM converter is established and it's good system performance is validated through experimental research. The experiment results show that fuzzy excitation control strategy has good static and dynamic performance and has importantly practical value for improving adaptive parameter capability and robustness of ACEG system.
