| چکیده | ||
| مطالعۀ حاضر به تحلیل خطوط اصلی انتقال آب شهر کرمانشاه در غرب ایران به منظور پتانسیلسنجی قابلیت استحصال انرژی برای تولید برق میپردازد. همواره برای کاهش فشار آب در خطوط انتقال آب، از شیرها یا تانکهای فشارشکن استفاده میشود، در حالی که میتوان با استفاده از توربینهای کوچک‌مقیاس از این انرژی بهره برد و بدون آثار جانبی به تولید برق تجدیدپذیر پرداخت. به این منظور، پنج خط آب‌رسانی اصلی شهر کرمانشاه بررسی شده است. با داشتن خصوصیات هیدرولیکی خطوط و مشخصات توپوگرافی آنها و بهرهگیری از معادلات بقا و پس از تعیین افتهای اصطکاکی طی مسیر، مقدار افت فشار محاسبه شده است. در ادامه، به محاسبۀ پتانسیل انرژی جریان آب در خطوط بررسی‌شده پرداخته شده است. نتایج نشان میدهد از میان پنج خط آب‌رسانی مطالعه‌شده، خط انتقال آب گاوشان به تصفیهخانۀ شهید نظری، به عنوان منبع اصلی تأمین آب شهر کرمانشاه، پتانسیل بسیار مناسبی برای تولید برق دارد. بررسی نتایج نشان میدهد این خط مناسب نصب و احداث میکروتوربینهای آبی است و میتوان حدود 4/2 مگاوات برق از آن تولید کرد. | ||

| چکیده [English] | ||
| The present study analyzes the main water pipelines of Kermanshah city in the western of Iran for the sake of power and electricity generation. Generally, pressure relief valves or break pressure tanks are used in water pipelines to regulate the water pressure. However, micro scales of hydro turbines could instead be used to generate green electricity without any side and harmful effects. For that purpose, the five main water pipelines in Kermanshah city were investigated numerically. With the help of hydraulic properties of the pipelines and also their topographic characteristics, the conservation laws were employed to find the pressure drop together with the energy potential along the pipelines. Of the transmission lines investigated in this study, the results revealed that the Gavoshan water transmission line is the best one based on the power generation potential. Moreover, the analyses show that 2.4 MW of electricity could be harnessed from that line. | ||
