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.
