چکیده

پراکنش منابع آب و بارندگی‌ها در سطح کشور متناسب نیستند، از این رو انتقال بین‌حوضه‌ای آب در قالب طرح‌های آبی برای جمع‌آوری، انتقال و ایجاد کیفیت مناسب برای توسعۀ موزون فعالیت‌های انسانی لازم است. این نوع طرح‌ها با توجه به مخزن بالادست و تونل انتقال آب به پایین‌دست شرایطی ترکیبی از مسائل هیدرولوژیکی (تراز آب مخزن) و هیدرولیکی (هیدرولیک لوله یا تونل انتقال) را در خود جای داده است. به همین دلیل، تحلیل و بررسی این مسایل برای به‌دست آوردن شرایط مورد نظر باید همزمان صورت گیرد. در این تحقیق، چهار سد (یلان، پشندگان، گوکان و زاینده‌رود) و سه تونل برای انتقال آب از سد یلان به سد زاینده رود در نظر گرفته شده است. برای مدل‌سازی و بهینه‌سازی این مطالعه، همزمان دو الگوریتم با یکدیگر و با نرم‌افزار EPANET به-صورت دینامیکی ارتباط دارند و مدل منابع آب، هیدرولیک و الگوریتم تکامل تفاضلی را حل می‌کند. از آنجا که انتقال آب در تونل‌ها به‌صورت تحت فشار است و کل مطالعه برای راندمان انتقال آب 95 درصد تعریف شده است، با افزایش ارتفاع هریک از سدها لازم است قطر تونل انتقال کاهش یابد تا بتواند راندمان مذکور را داشته باشد. نتایج تحقیق نشان می‌دهد که الگوریتم تکامل تفاضلی در حالتی که ضریب مقیاس و ضریب احتمال ترکیب (F و Cr) برابر 5/0 و 5/0 و جمعیت اولیه 1000 عضوی و نسل 1500تایی است بهترین جواب را از نظر هزینه ارائه می‌دهد. هزینۀ بهینۀ ارائه شده با الگوریتم تکامل تفاضلی برای راندمان انتقال 95 درصد برابر 5/14014 میلیارد ریال است.

چکیده [English]

Since the distribution of water resources and rainfall in the country is not proportionate. Inter-basin water transfer in the form of water projects for the collection, transmission and creation of appropriate quality for development of human activity is necessary. On the other hand, this type of plan according to the upstream reservoir and downstream water transfer tunnel has combination of problems hydrology (water level of the reservoir) and hydraulic (hydraulic pipe or tunnel). The hydrology and hydraulic analysis to obtain the desired conditions should be simultaneous. In this studied four dams (Yalan, Pashanedegan, Gokan and Zayanehroud) and three tunnels to transfer water from the Yalan dam to Pashandegan dam have been used. In order to simulate and optimize this project, two algorithms associated with each other and connected to EPANET dynamically for solving water resources and hydraulic model and differential evolution algorithm. Since the water in the tunnels is under pressure for the entire study for water transfer efficiency of 95 percent is defined, by increasing the height of each of the dams should reduce the tunnel diameter. The results showed that weighting factor of 0.5 and crossover constant of 0.5 and population and generation of 1000 and 1500 respectively has provided an optimal solution in DE algorithm. Optimal cost by 95% transfer efficiency is equal to 14014.5 Billion riyals.
