چکیده مقاله :
در ژنراتور القایی تغذیه دوسویه، سیم‌پیچ‌های استاتور مستقیماً به شبکه متصل می‌شوند؛ در صورتی که سیم‌پیچ‌های روتور از طریق مبدل‌های الکترونیک قدرت به شبکه متصل می‌شوند. این مبدل‌ها شامل Back-to-Back و مبدل‌های ماتریسی مستقیم و غیرمستقیم هستند. مبدل‌های Back-to-Back دارای ساختار دومرحله‌ای می‌باشند که تلفات نسبتاً بالا و با وجود خازن لینک DC، حجم و وزن زیادی دارند. در این مقاله برای برطرف‌کردن مشکل مبدل Back-to-Back ، مبدل‌های ماتریسی جایگزین این مبدل پیشنهاد می‌گردد و از کنترل مستقیم توان در ژنراتورهای القایی تغذیه دوسویه با استفاده از مبدل ماتریسی استفاده شده است. این مبدل در طول تغییرات توان مرجع و توربین به‌خوبی مقادیر مرجع را دنبال می‌کند. چالش اصلی استفاده از مبدل‌ها این است که باعث ایجاد هارمونیک و نوسانات توان می‌شوند که برای برطرف‌کردن این مشکل از فیلتر پسیو هیبریدی در ورودی و خروجی مبدل ماتریسی استفاده شده که باعث کاهش نوسانات توان‌های اکتیو و راکتیو و بهبود THD جریان و کیفیت توان می‌شود. به‌علاوه پاسخ دینامیکی دقیق به هنگام تغییرات توان مرجع دارد و این عدم نیاز به حلقه‌های کنترل جریان، باعث ایجاد ساختار ساده با کمترین محاسبات شده است. نتیجه حاصل از روش پیشنهادی با استفاده از فیلتر و بدون فیلتر مقایسه می‌شود که نتایج نشان از عملکرد خوب و برتری استفاده از فیلتر دارد.
In two-way feeding induction generators, the stator coils connect directly to the grid, while the rotor coils connect through power electronic converters. Back-to-Back (BTB) converters are commonly used but suffer from high losses, size, and weight due to their two-stage structure and DC link capacitor. This paper proposes replacing BTB converters with matrix converters for improved efficiency and compactness. The proposed method utilizes direct power control in the matrix converter for superior tracking of reference values during changes in both reference and turbine power. However, power electronic converters can introduce harmonics and power fluctuations. To address this, a passive hybrid filter is employed at the converter's input and output. This filter reduces active and reactive power fluctuations, improves Total Harmonic Distortion (THD), and enhances overall power quality. Additionally, the matrix converter's fast dynamic response to reference power changes eliminates the need for complex current control loops, resulting in a simpler structure with minimal calculations. The paper compares the performance of the proposed method (matrix converter with filter) against scenarios with and without a filter. The results demonstrate the filter's effectiveness and superiority in achieving optimal performance.
