ملخص المقالة :
در اين مقاله از يك سيستم (HVDC Light) VSC-HVDC براي انتقال توان ميان شبكه‌هاي توزيع آسنكرون استفاده شده است. روش كنترل مستقيم توان با استفاده از مدولاسيون SVM براي اين روش به كار رفته است. همچنين از يك تخمين‌زن شار به جاي سنسور ولتاژ خط استفاده شده است. استفاده از شار مجازي و مدولاسيون SVM باعث مي‌شود كه هارمونيك جريان كمتري توليد گردد و كيفيت توان به طور قابل توجهي افزايش يابد. شبيه‌سازي‌ها حاكي از آن هستند كه اين روش براي مستهلك‌كردن نوسانات و اصلاح پايداري در سيستم توزيع، هنگامي كه جهت توان معكوس مي‌شود مناسب است. همچنين پاسخ ديناميكي مطلوب و به دست آوردن ضريب قدرت واحد در سمت يكسوكننده از مزيت‌هاي ديگر اين روش كنترل است.
