Abstract    In this paper, the effect of number and fault current limiter(FCL) location has been investigated in order to have maximum reduction of short circuit current level in all buses in a real network. To do so, the faulty buses were identified in terms of short circuit current level by computing short circuits on the desired network. Then, while the fault current limit was modeled, its optimal location and amount for the greatest reduction in the fault current level of the whole critical buses was determined. Optimization computations have been done using the genetic algorithm and method of reducing the search space and all implementation stages of the proposed algorithm and reduction of search space has been conducted in DIgSILENT software using programming language DPL. The obtained results indicate the high efficiency of the proposed method in reducing the short circuit current level of faulty buses and simultaneous improving the power quality.

چکیده    در این مقاله تأثیر تعداد و مکان محدود کننندههای جریان خطا در یک شبکه واقعی بررسی شده است. این امر به منظور کاهش حداکثری سطح جریان اتصال کوتاه در تمام باسها صورت گرفته است. برای این منظور ابتدا باسهایی که دارای مشکل افزایش سطح جریان اتصال کوتاه هستند بر حسب میزان افزایش سطح جریان اتصال کوتاه در شبکه مورد بررسی، شناسایی و اولویت دهی شدهاند. سپس ضمن مدلسازی محدود کنندههای جریان خطا، تعداد، مکان و میزان بهینه آنها برای کاهش حداکثری سطح جریان اتصال کوتاه در تمام باسهای دارای مشکل، تعیین شدهاند. محاسبات بهینه سازی با استفاده از الگوریتم ژنتیک صورت پذیرفته است. الگوریتم کاهش فضای جستجو و سایر محاسبات مربوطه با استفاده از فضای برنامه نویسی DPL در نرم افزار DIgSILENT، برنامه نویسی و اجرا شدهاند. نتایج، موفقیت زیاد الگوریتم پیشنهادی، در کاهش سطح جریان اتصال کوتاه باسهای دارای مشکل و به طور همزمان بهبود کیفیت توان را نشان میدهند.
