چکیده
چکیده: امروزه پیشرفت روز افزون در فناوری، گسترش و توسعه نیازهای بشر به تکنولوژی‌های پایدار سبب شده تا توجه به انرژی الکتریکی بیش از گذشته در مرکز توجه قرار گیرد. از این‌رو افزایش قابلیت اطمینان در سیستم های ­الکتریکی در صنعت برق بسیار حائز اهمیت می‌باشد. هدف از این پژوهش ارائه مدل ریاضی جهت محاسبه و افزایش قابلیت اطمینان در شبکه توزیع برق قدرت می­باشد. این پژوهش از نظر هدف و نتایج، کاربردی و از منظر روش و ماهیت اجرا مبتنی بر پژوهش عملیاتی است که با بهره­گیری از مدل‌سازی ریاضی و با استفاده از نرم‌افزار پایتون بر اساس داده‌هایی در بازه زمانی 1398 تا 1402 انجام شده است. یافته‌ها نشان می‌دهد پارامترهایی نظیر دژنکتور‌ها، باسبارهای فشار قوی و فشار ضعیف، ترانس‌های قدرت 20 کیلو ولت به 400 ولت، کابل‌های ارتباطی، خازن‌، ژنراتور و یو پی اس‌ در محاسبه قابلیت اطمینان این شبکه از اهمیت بالاتری برخوردار هستند. از این رو با عنایت به هدف و محدودیت­های متناظر با هر پارامتر مدل ریاضی مناسب ارائه شده است. نتایج نشان می­دهد پس از 50 تکرار و شبیه‌سازی، خط فوق اضطراری از بین چهار فیدرخروجی دارای اهمیت و رتبه بالاتری در قابلیت اطمینان می‌باشد. ضمنا بر اساس مدل ارائه شده مشاهده شده است کل خط بیست کیلوولت تحت بررسی دارای 0.67 درجه از قابلیت اطمینان می‌باشد. نتایج این تحقیق می­تواند مبنای مناسبی جهت اجرای پروژه­های پژوهشی و عملیاتی در شبکه‌های گسترده شعاعی در صنعت برق به شمار آید.

چکیده English

Today, the increasing progress in technology, the expansion and development of human needs for sustainable technologies have caused attention to electric energy to be in the center of attention more than in the past. Therefore, increasing the reliability of electrical systems in the power industry is very important. The purpose of this research is to provide a mathematical model to calculate and increase reliability in the power distribution network. This research is practical in terms of its purpose and results, and in terms of the method and nature of implementation, it is based on operational research that was conducted using mathematical modeling and using Python software based on data from 1398 to 1402. The findings show that parameters such as generators, high pressure and low pressure busbars, 20 kV to 400 V power transformers, communication cables, capacitors, generators and UPS are more important in calculating the reliability of this network. Therefore, according to the purpose and the corresponding limitations, a suitable mathematical model has been presented for each parameter. The results show that after 50 repetitions and simulations, the ultra-emergency line has a higher importance and rank in reliability among the four output feeders. Also, based on the presented model, it has been observed that the entire 20 kV line under investigation has 0.67 degrees of reliability. The results of this research can be considered as a suitable basis for the implementation of research and operational projects in wide radial networks in the electricity industry.
