The vector control research of brushless doubly-fed shaft generator for running independently

As the ship auxiliary power system in ship electrical power system, ship shaft power generation system plays a vital role for the whole ship power supply stability and reliability. The variable speed constant frequency and constant voltage problem is a key technology to ensure the ship shaft power generation system stable and reliable operation. Aiming at this problem, this paper combines vector control strategy based on the stator power winding flux oriented with fuzzy adaptive PID controllers to control the independent operation of brushless doubly-fed shaft generator (BDFG) system. Combined with the Matlab/Simulink software, the ship anti-interference performance of BDFG shaft generator system is studied. Simulation results show that the system has good dynamic and static stability under this control strategy.
