چکیده مقاله :
در این مقاله یک روش کنترلی جدید جهت جذب حداکثر توان از توربین بادی مغناطیس دائم مجهز به مبدل ماتریسی ارائه می‌شود. در این روش با محاسبه سرعت بهینه دوران توربین و پیاده‌سازی روش جستجوی صعود، میزان جذب توان از باد در گستره تغییرات سرعت باد کنترل می‌شود. این فرایند بدون نیاز به کنترل دامنه و فرکانس ولتاژ ترمینال‌های ورودی مبدل، تخمین موقعیت روتور و استفاده از روش‌های کنترل برداری پیاده‌سازی می‌شود. در این روش با کنترل دامنه و فاز ولتاژ خروجی مبدل و از طريق راكتانس نشتي ترانسفوماتور، میزان تزریق توان به شبکه، گشتاور مغناطیسی و متناسب با آن سرعت توربین به طور غیر مستقیم کنترل می‌شود، به نحوی که همواره در سرعت‌های مختلف باد، بیشترین توان ممکن از باد، جذب و تحت ضریب قدرت واحد به شبکه تزریق گردد. در این راستا با طراحی مبدل ماتریسی مستقیم، الگوریتم کنترلی پیشنهادشده در محیط برنامه‌ریزی Matlab پیاده‌سازی شده و سپس نتایج حاصل مورد بررسی و تحلیل قرار می‌گیرند.
In this paper, a new control method is proposed for extracting the maximum power of wind turbines equipped with Permanent Magnet Synchronous Generator (PMSG), which is connected to the grid via a matrix converter. The method calculates the optimal rotation speed of wind turbine and finds the optimal operation point by hill climbing method. The proposed method is simple and it does not need to use some complex methods such as field oriented and rotor position estimation. Wind turbine speed, electrical torque and consequently maximum output power of wind turbine are obtained by the perfect control of output phases and amplitudes of matrix converter. Moreover, the maximum power is injected to the grid under unity power factor. The proposed method is simulated in MATLAB programming software and the obtained results approve the validity of the method.
