Optimal pipelines sizing for distribution systems with draw-off stations

الملخص EN

The present study focuses on developing a cost function for pump-pipelines system with emitters randomly distributed along the pipelines.

The objective function is based on the capital cost of the piping system, pumps and the cost of energy required to operate the system.

Employing the least annual cost principle to obtain the optimal diameter of each pipe leads to a nonlinear system of equations.

A solution procedure based on an iterative scheme is proposed and examined for three case studies.

The first case is a three-parallel pipeline system with 12 emitters.

The second case is a two-pipeline system of the actual irrigation network at King Abdulaziz University Campus, with 26 emitters.

A single pipeline 5.8-km long with three draw-off points is the third case study.
