چکیده مقاله :
اخیراً برای حذف هارمونیک‌ها و ارتقاء ضریب توان در شبکه‌های قدرت، فیلترهای اکتیو مورد توجه فراوان قرار گرفته‌اند. از مزایای این گونه فیلترها، حجم کمتر و مشخصات جبران کنندگی بهتر آن‌ها نسبت به فیلترهای پسیو است. در این مقاله استراتژی کنترلی نوین برای دو نوع فیلتر اکتیو VSI و CSI پیشنهاد شده است و سپس این دو نوع فیلتر از نظر میزان کاهش THD جریان بارغیرخطی مورد مقایسه گرفته‌اند. استراتژی کنترلی پیشنهادی برای فیلتر اکتیو VSI مبتنی بر علامت‌های لغزش و منبع جریان و استراتژی کنترلی پیشنهادی فیلتر اکتیو CSI فقط مبتنی بر علامت لغزش است. کلیه‌ی شبیه‌سازی‌ها در محیط MATLAB/Simulink انجام گرفته است. نتایج شبیه‌سازی نشان می‌دهد که روش‌های کنترلی پیشنهادی برای هر دو نوع فیلتر بهتر از روش‌های کنترلی قبلی می‌باشد و فیلتر اکتیو CSI عملکرد بهتری نسبت به فیلتر اکتیو VSI با در نظر گرفتن ناحیه‌ی مرده (برای جلوگیری از اتصال کوتاه شدن منبع) دارد
Recently to eliminate the harmonics and improve the power factor of the power networks, much attention has been attracted to active filters. The advantages of these filters are lower volume and their better compensating characteristics than the passive filters. In conventional sliding mode controllers, the source current waveform is fluctuated in near to zero values. In this paper, using a new sliding technique, lower Total Harmonic Distortion (THD) in source current is obtained and the current waveform is improved. As well as, two novel control strategies for two types of active filters, VSI and CSI is proposed and then these two types of filters are compared to reduce THD value of source current.The proposed controlled strategies are simulated by MATLAB/Simulink. The Simulation results confirm that the proposed strategies reduce the THD of source current more than other strategies, and active filter based on CSI has a better performance than active filter based on VSI with a dead time area (for avoiding short circuit of the source) in high powers.
