Sensorless Drive for Wound Rotor Synchronous Generator with Brushless Excitation System in Maritime DC Microgrid
2023 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED)(2023)
摘要
The stator flux oriented control(SFOC) enables sensorless drive for a wound rotor synchronous generator (WRSG) in maritime dc microgrid. However, there have been few studies that considers the dynamics of the pilot exciter, which is used to indirectly control the field current of the main exciter. This paper proposes the SFOC considering the dynamics of the pilot exciter. The proposed SFOC finely tunes flux regulator based on the approximated model of the pilot exciter. Simulation and experimental tests were conducted with a 1.8 MW WRSG to verify the proposed SFOC.
