Abstract

Penelitian ini mengembangkan model simulasi dan optimasi berbasis MATLAB untuk pemilihan dan penempatan pompa pada jaringan distribusi fluida. Sistem ini dimodelkan sebagai jaringan pipa steady-state yang terdiri dari enam node dan sebelas pipa, menggabungkan konfigurasi loop terbuka dan tertutup. Persamaan pengaturan nonlinier berasal dari prinsip konservasi massa dan keseimbangan energi. Metode Newton-Raphson digunakan untuk memecahkan laju aliran secara berulang sambil memperhitungkan resistansi pipa dan kondisi batas tekanan. Head Loss dihitung menggunakan persamaan Darcy-Weisbach, dan Total Dynamic Head (TDH) dievaluasi di bawah skenario penempatan pompa yang berbeda. Skenario A dan B membandingkan skema pemompaan terpusat dan terdistribusi. Skenario A, yang melibatkan tiga pompa non-identik yang ditempatkan di lokasi permintaan tinggi, mencapai kinerja hidraulik yang lebih baik dan mengurangi total permintaan daya hingga 23% dibandingkan dengan konfigurasi terdistribusi (Skenario B), yang menggunakan empat pompa identik yang beroperasi secara paralel. Model ini berfungsi sebagai alat yang fleksibel untuk desain sistem pompa awal dan mendukung pengambilan keputusan dalam aplikasi teknik praktis.

This study developed a MATLAB-based simulation and optimization model for pump selection and placement in fluid distribution networks. The system was modeled as a steady-state pipe network consisting of six nodes and eleven pipes, combining both open- and closed-loop configurations. The nonlinear governing equations were derived from mass conservation and energy balance principles. The Newton-Raphson method was employed to iteratively solve for flow rates while accounting for pipe resistance and pressure boundary conditions. Head losses were calculated using the Darcy-Weisbach equation, and total dynamic head (TDH) was evaluated under different pump placement scenarios. Scenarios A and B compared centralized and distributed pumping schemes. Scenario A, involving three non-identical pumps placed at high-demand locations, achieved better hydraulic performance and reduced total power demand by up to 23% compared to the distributed configuration (Scenario B), which utilized four identical pumps operating in parallel. The model serves as a flexible tool for preliminary pump system design and supports decision-making in practical engineering applications.
