摘要: Wind turbines have become the most cost-effective renewable energy systems available today and are now completely competitive with essentially all conventional generation systems. However, wind stochasticity results in fluctuations output power as well undesirable dynamic loading of drive train during high turbulence. A model-based predictive control strategy for field-oriented a doubly fed induction generator is presented. The region defined over two profiles: average speeds below above equipment rating, subject to assigned constraints maximum allowable system frequency limit generating system. To meet objectives maximising capture alleviation fatigue loads, each WGS component blocks modelled separately so explore associated trade-offs. Simulations, carried out under Matlab ® environment, serve verify that proposed paradigm performs better than classical linear proportional-integral controller achieving regulation torsional dynamics while maintaining optimal operation.
