A novel open-winding brushless doubly-fed reluctance machine and its power decoupling control system are proposed for wind power generator application. The control winding of brushless doubly-fed reluctance generator (BDFRG) is designed as openwinding structure, and the double-end power supply cascade two-level inverter is adopted to excite the open-winding BDFRG. This topology structure has be...
The paper considers aspects of scalar V/f control, vector control and direct torque (and flux) control (DTC) of an emerging cost-effective technology for limited speed range applications the brushless doubly fed reluctance machine (BDFRM). Apart from giving a comprehensive review of the various control methods, its major contribution is the presentation and experimental verification of a sensor...
The Brushless Doubly-Fed Reluctance Machine (BDFRM) is being considered as a viable generator alternative to be used in wind turbines. However, a literature review shows that there is still a lack of researches to define a design procedure to make this machine commercial. This paper aims to address this issue by considering a new BDFRM design method using a reluctance network approach with focu...
Parameter and Performance Comparison of Doubly Fed Brushless Machine With Cage and Reluctance Rotors
The cage and reluctance rotors are two major types of rotor structures used in the doubly fed brushless machine (DFBM). In order to study comparatively the effects of different rotor structure on the DFBM, a prototype machine has been specially designed and built. The experimental parameter and performance comparisons between the axially laminated anisotropic (ALA) and cage-rotor machines are p...
Introduction. Nowadays, global investment in renewable energy sources has been growing intensely. In particular, we mention here that wind source of grown recently. Purpose. Comparative study between sliding mode control and vector a brushless doubly fed reluctance generator based on conversion systems. Methods. This paper deals with conceptual analysis comparative two techniques promising low-...
A novel model reference adaptive system for the rotor position/speed estimation and sensorless operation of a brushless doubly fed reluctance generator with maximum power point tracking is presented. Its main advantage over existing designs are inherent robustness stability afforded by complete parameter independence using only measured currents converter-fed (secondary) winding. In addition, r...
Variable speed operation of a wind turbine generator improves its energy capturing capability. Up to the present, the machines employed have been induction machines, conventional synchronous machines or DC machines. The major drawback of these machines is that a complicated arrangement of slip rings or commutators with brushes, and a full-rating power converter are required. Reliability and cos...
The Brushless Doubly Fed Reluctance Machine (BDFRM) is an emerging alternative for variable speed drive systems, providing a significant downsizing of the power electronics converter. This paper proposes new view on machine equations, allowing reuse standard control system design conventional synchronous and asynchronous machines: cascade with inner current control- outer loop. assumptions simp...
This paper presents dynamic modeling and simulation of Brushless Doubly Fed Induction Generator (BDFIG) as an alternative for variable speed wind power applications. The mathematic models of active and reactive power for BDFIG have been developed. The power control systems of a 75 kVA generator and wind turbine were simulated in Matlab/Simulink/SymPower Systems. The generator’s control system i...
