چکیده

در این مقاله روشی برمبنای درخت تصمیم برای حفاظت ازدست‌رفتن تحریک (LOE) ژنراتور سنکرون در حضور کنترل‌کننده یک‌پارچه پخش توان (UPFC) ارائه شده است. حضور UPFC سبب می‌شود که رله بردی دچار تأخیر در شناسایی LOE شود. در روش پیشنهادی متغیرهای مختلف درنظر گرفته شده‌اند. در الگوهای مختلف تست و آموزش و با استفاده از الگوریتم‌های هوشمند، مناسب‌ترین متغیرها انتخاب شده‌اند تا دقت در زمان آشکارسازی خطای LOE را افزایش دهند. نتایج شبیه‌سازی در نرم‌افزار متلب/سیمولینک، درستی روش پیشنهادی را در بارگذاری‌های مختلف، درصدهای مختلف ازدست‌رفتن تحریک، حالت‌های مختلف خطا و شرایط نویزی تأیید می‌کند. نتایج نشان می‌دهد که روش پیشنهادی نسبت به روش‌های سنتی، در تفکیک خطاهای LOE و خطاهای خارجی تحت شرایط عملکرد ناشناخته، دقت دسته‌بندی بهتر و سرعت تشخیص بالاتری دارد.

چکیده [English]

In this paper, a Decision Tree-based method of Loss of Excitation (LOE) Protection of Synchronous Generators in Presence of Unified Power Flow Controller (UPFC) is presented. The presence of UPFC causes the Berdy relay to be delayed in detecting LOE. In the proposed method, different variables are considered and in the various test and training patterns and using intelligent algorithms, the most suitable variables selected to increases the accuracy in detecting the time of LOE. The simulation results in Matlab/Simulink software validate the accuracy of the proposed method in various loadings, different percentages of loss of excitation, various scenarios of fault and noisy conditions. The results reveal that the proposed method has a better classification accuracy and a higher identification speed under new and unseen operating conditions of LOE and external faults compared to traditional methods.
