چکیده مقاله :
در اين مقاله ساختار جدیدي براي محدودكنندههاي جریان اتصال کوتاه پيشنهاد شده است. در محدودكننده پیشنهادی بهجاي استفاده از ابررسانا در ساخت سيمپيچ، از مس استفاده شده و تلفات سيمپيچي و همچنين تلفات ناشي از ادوات الكترونيك قدرت با استفاده از يك مدار كمكي جبران شده است. همانگونه كه نشان داده خواهد شد محدودكننده مذکور با كاركردي مناسبتر در زمان اتصال كوتاه، تأثیر بسيار کمتری بر مشخصههای سیستم در كاركرد عادي در مقايسه با آنچه كه تاكنون با استفاده از ابررسانا پيشنهاد شده بود از خود نشان ميدهد. امکان ساخت بدون نياز به تکنولوژی ابررسانا و عدم وجود مدار کنترل اصليترين مزاياي مدار پيشنهادي ميباشد. آناليز دقيق و مشخصههاي طراحي براي راكتور DC ارائهشده و شبیهسازیهای لازم با استفاده از نرمافزار PSCAD/EMTDC و براي نشاندادن عملكرد مناسب محدودكننده در جريانهاي اتصال كوتاه و عملكرد مناسبتر آن نسبت به نوع ابررسانا در كار عادي سيستم قدرت انجام شده است. نتایج آزمایشگاهی نيز بهدست آمده و تشابه آنها با نتایج شبیهسازی نشاندهنده کارآیی مناسب مدار جدید پیشنهادی برای محدودکردن جریان اتصال کوتاه میباشد.
In this paper a new structure for fault current limiter is proposed. In proposed structure the superconductor coil is replaced by a copper coil and the losses of copper coil and power electronic devices are compensated by an auxiliary circuit. The results show that the proposed structure has less undesired effect on normal operation of system compared with ordinary superconductor type. The main advantageous of proposed structure are no need to superconductor technology and its control-less operation. The analytical analysis and designing characteristics for DC reactor are presented. Also, the simulation and experimental results are presented to show the effectiveness of proposed structure in fault current limitation.
