Abstract

Abstract : In this study, a control scheme for the stand‐alone generation system based on brushless doubly‐fed machine (BDFM) is presented. The output voltage amplitude and frequency are kept constant under variable rotor speed and load by regulating the amplitude and frequency of the control winding (CW) current of BDFM appropriately. The control scheme utilises a CW current vector controller as the inner loop, and a power winding voltage amplitude controller and a frequency controller as the outer loop. The proposed control scheme has been implemented on a prototype BDFM designed for the variable‐speed stand‐alone ship shaft generation application. Moreover, the satisfactory dynamic performance and low total harmonic distortion of the output voltage in the proposed stand‐alone generation system is verified by experiments with two kinds of typical loads: three‐phase induction motor load and three‐phase RL inductive load.
