ملخص المقالة :
در شرایط عملکرد عادی یا خطای ژنراتورهای القایی با تغذیه دوگانه، مؤلفه‌های فرکانسی مختلفی در هر یک از سیم‌پیچ‌های استاتور و روتور یا در بخش مکانیکی می‌تواند ایجاد گردند که قابل انتقال به طرف‌های دیگر هستند و می‌توانند مؤلفه‌های فرکانسی دیگری ایجاد کنند. در این مقاله ابتدا روابط تحلیلی دقیقی برای این مؤلفه‌های فرکانسی و انتقال آنها به طرف‌های دیگر بر حسب دامنه و فاز مؤلفه‌های فرکانسی ارائه گردیده است که صورت کامل‌تری از روابط ارائه‌شده در آخرین مقالات در این زمینه است. سپس مدلی برای ژنراتور تغذیه دوگانه ارائه شده که با دقت خوبی می‌تواند مؤلفه‌های فرکانسی را در بخش‌های الکتریکی و مکانیکی ژنراتور محاسبه و مدل‌سازی نماید. در انتها صحت و دقت روابط و مدل ارائه‌شده با مطالعات موردی صحت‌سنجی شده است.
