| چکیده | ||
| شبکه توزیع آب شهر کلیبر به دلیل ویژگی خاص توپوگرافی شهر، دارای 7 شیر فشارشکن است که به صورت تجربی در موقعیتهای مختلف شبکه نصب شده است تا مازاد فشار موجود در شبکه مدیریت شود. در این تحقیق، تاثیر جانمایی هوشمند شیرهای فشارشکن با به کارگیری شاخص مکانیابی شیر، به منظور کاهش میزان نشت و افزایش قابلیت اطمینان شبکه بررسی میشود. هدف کمینهسازی نشت ساعتی با تعیین موقعیت جدید شیرها و بهینهسازی برنامه ساعتی عملکرد آنها میباشد که در کنار کمینهسازی نشت به عنوان تابع هدف، قید حداقل فشار در سه حالت عدم اعمال قید فشار (قید حداقل فشار برابر صفر متر)، تامین آب در ورودی ساختمان (حداقل قید فشار برابر 10 متر) و تامین آب برای یک ساختمان چهار طبقه (حداقل قید فشار برابر 26 متر) به عنوان تابع پنالتی در کنار تابع هدف در نظر گرفته شده است. برای این منظور از ترکیب الگوریتم جامعه مورچگان با شبیهساز ایپانت در محیط متلب استفاده شده است. بررسی نتایج نشان میدهد که با جانمایی هوشمند شیرهای فشارشکن موجود در شبکه کلیبر و بهینهسازی برنامه ساعتی عملکرد آنها، میزان نشت شبکه در حدود 15/9درصد نسبت به حالت تنظیم تجربی شیرهای فشارشکن کاهش و قابلیت اطمینان شبکه در حدود 15/5 درصد افزایش مییابد که نشان دهنده تاثیر برنامهریزی هوشمند شبکههای توزیع آب در بهبود کارائی هیدرولیکی آنها میباشد. | ||

| Due to the special topography of Kaleybar city, the water distribution network of this city has 7 pressure-reducing valves that have been experimentally installed in different locations to manage the extra pressure in the network. In this research, the effect of the intelligent emplacement of pressure-reducing valves is investigated by using the valve selection index to reduce leakage and increase network reliability. The aim is to minimize hourly leakage by determining the optimal location and setting of valves, In addition to the minimization of leakage as the objective function, the minimum pressure restriction in three cases of no pressure restriction (0 meters), water supply at the entrance of the building (10 meters) and water supply for a four-story building (26 m) is considered as a penalty function. For this purpose, a combination of the Ant Colony Optimization Algorithm with the EPANET simulator in MATLAB has been used. The results show that with the intelligent emplacement of pressure-reducing valves in Kaleybar City, the leakage of the network has been decreased by 15.9 percent and the reliability of the network has been increased by 15. 5 percent, which shows the effect of the proposed method in improving the hydraulic performance of water distribution network. | ||
