ارايه روشي نو براي عملكرد بي وقفه توربين بادي مجهز به ژنراتورالقايي از دو سو تغذيه در طي بروز اتصال كوتاه در شبكه با استفاده ازSTATCOM
مقاله رشته مهندسی برق که در کنفرانس بین المللی برق ایران به چاپ رسیده است.
چکیده:امروزه با افزايش نفوذ منابع انرژي تجديد پذير از جمله انرژي باد در سيستم هاي قدرت، ما را با مشكلات جديدي روبرو ساخته است. يكي از اين مشكلات، عملكرد توربين هاي بادي مجهز به ژنراتور القايي از دو سو تغذيه(DFIG) در طي بروز اتصال كوتاه در شبكه قدرت مي باشد. اتصال كوتاه روي سيستم قدرت حتي اگر از محل توربين دور باشد باعث ايجاد افت ولتاژ در نقطه اتصال توربين بادي به شبكه مي شود. اين امر باعث افزايش جريان در سيم پيچ هاي استاتور مي شود وبه خاطر كوپل مغناطيسي بين استاتور و روتور، اين جريان در مدار روتور و مبدل الكترونيك قدرت طرف روتور ديده مي شود كه منجر به آسيب ديدن مبدل الكترونيك قدرت مي شود. به همين علت در توربين هاي بادي مجهز به DFIG، هنگامي كه يك حالت غير عادي در ولتاژ شبكه شناسايي شود، از سيستم قدرت جدا مي شوند. در اين مقاله روشي نو براي عملكرد بي وقفه توربين بادي مجهز به DFIG در طي بروز اتصال كوتاه در شبكه با استفاده از جبران ساز راكتيو سنكرون(STATCOM) ارايه شده است. سپس درستي روش با شبيه سازي سيستم قدرت نمونه در محيط PSCAD/EMTDC تاييد مي شود.
