Tujuan penelitian ini adalah menghasilkan program simulasi motor listrik yang mampu menampilkan karakteristik dinamik arus stator motor induksi tiga fasa. Metodologi penyelesaian penelitian ini dimulai dari ide dasar, studi literature, perancangan, pembuatan dan pengujian software. Penerapan metode Gear dibuat dengan bahasa Python. Hasil simulasi arus stator yang diamati pada kondisi transien dan tunak, yaitu nilai maksimum, nilai minimum, waktu transisi dan nilai peak-to-peak. Hasil simulasi tersebut dibandingkan dengan hasil simulasi menggunakan modul solver ODE15 yang tersedia pada Matlab. Simulator yang dibuat dapat mensimulasikan perilaku dinamik motor induksi tiga fasa dengan perbedaan 1,5 %, 0,93 % dan 1,5 % secara berturut-turut untuk arus stator fasa-a, arus stator fasa-b dan arus stator fasa-c.

ABSTRACT

This study discusses the process and results of implementing the stator current modeling of the three-phase induction motor using the Gear method. This study aims to produce an electric motor simulation program that can display the dynamic characteristics of the stator current of a three-phase induction motor. The methodology of completing this research is the basic idea, literature study, design, creation, and software testing. The application of the Gear method is made with the Python programming language. Stator current simulation results are observed in transient and steady conditions, namely the maximum value, minimum value, transition time, and peak-to-peak value. The simulation results are compared with the simulation results using the ODE15 solver module available in Matlab. The simulator created can simulate the dynamic behavior of the stator current of a three-phase induction motor with a difference of 1.5%, 0.93%, and 1.5% respectively for phase-a, phase-b, and phase-c.
