Vector Control of Brushless Doubly-Fed Machine for High Power Stand-Alone Power Generation

Article Preview

Abstract:

In this paper, a novel variable speed constant frequency brushless doubly-fed induction generator system using back-to-back multilevel converters for high power stand-alone power generation is described. According to control target, the unified reference-frame model is used to develop an improved forced power stator flux oriented vector control strategy. The similarities and differences between the grid-connected and stand-alone topology and control strategy are also specialty analyzed and compared. Simulation results prove the feasibility and validity of the proposed model, theoretical analysis and excellent performance of the proposed control scheme.
