Adaptive Variable Speed Control Scheme for Wind Based on PFC of BLDC Drive Applications

The wind turbine acts as a prime-mover for doubly fed BLDC generator. To make the system stable, proper monitoring is required or sometimes an auxiliary system can also be a good option, which can support the primary system during undesirable conditions. The simulation results show a significant enhancement in shortening development time and improving dynamic performance of the BLDC motor compared to the conventional speed control of BLDC motor drive. The wind turbine acts as a prime-mover for doubly fed BLDC generator. The three phase BLDC motor has wide applications in industries due to its rugged construction, efficiency and low cost. Neutral point clamped is used for estimation of feedback controller parameters for three phase BLDC motor fed from wind turbine .Neutral point clamped offers certain advantages such as simple steps. The PFC BL-Luo converter has been designed to operate in DICM and to act as an inherent power factor pre-regulator. An electronic commutation of the BLDC motor has been used which utilizes a low-frequency operation of VSI for reduced switching losses. The simulation results show a significant enhancement in variable industrial applications and improving dynamic performance of the BLDC motor compared to the conventional speed control of BLDC motor drive. The proposed concept can be implemented to adaptive variable speed control scheme for wind energy based BLDC motor using Matlab/Simulink software
