چکیده

در این مقاله یک مدل تحلیلی برای ژنراتور القایی اتصال سری ((SCIG پیشنهاد شده است. همچنین عملکرد SCIG و ژنراتور القایی معمولی (IG) به صورت آزمایشگاهی در حالت منفصل از شبکه مورد بررسی قرارگرفته و مقایسه شده‌اند. پس از معرفی ژنراتور القایی اتصال سری و حالات بهره‌برداری مختلف آن، یک مدل دینامیکی مناسب برای این ژنراتور ارائه شده است. نتایج آزمایشات انجام شده نشان می‌دهند ژنراتور القایی اتصال سری دارای برخی مشخصه‌های مشابه با ژنراتور القایی معمولی می‌باشد. اما SCIG دارای محدوده سرعت عملکرد وسیعتر و قابلیت بهره‌برداری در سطح ولتاژ بالاتر است. با توجه به این ویژگیها، می‌توان این ماشین را به عنوان یک کاندید برای نسل جدیدی از ژنراتورهای بادی معرفی کرد و از آن در نیروگاه‌های بادی با سرعت باد بالا بدون نیاز به جعبه دنده استفاده نمود.

چکیده [English]

This paper proposes an analytical dynamic model for series connected induction generator (SCIG) and investigates the experimental performance of SCIG and compares it with an ordinary induction generator (IG) at standalone operating mode. After introducing the structure of series connected induction generator and its different modes of performance, a suitable dynamic model is proposed for this machine. The results of experimental investigations indicate that series connected induction generator and ordinary induction generator have some similar behaviors. But, SCIG has higher speed range without any need to gearbox and capability of operating at higher voltage level. So it may be proposed as a new suitable candidate for wind power generation at regions with high-speed wind.
