Abstract

Prinsip kerja kereta maglev adalah adanya interaksi antar kutub ? kutub magnet yang terdapat pada kereta dengan kutub ? kutub magnet yang berada di sepanjang jalur kereta. Kutub ? kutub magnet tersebut terbuat dari kumparan dengan kawat superkonduktor yang dialiri arus listrik. Secara teori besar medan magnet tergantung pada besar arus yang mengalir, inti kumparan dan jumlah belitan. Pada penelitian ini telah dibuat sebuah kumparan dengan inti besi berukuran panjang 5 cm dan diameter 8mm dengan jumlah belitan sebanyak 400 putaran. Pengujian karakteristik dilakukan dengan mengalirkan arus listrik searah pada kumparan dengan memvariasikan besaran arusnya. Pengukuran medan magnet dilakukan pada jarak tertentu antara 0 s.d 5 cm dengan rentang 0,5 cm dari ujung kumparan. Dihasilkan medan magnet paling besar berada pada jarak terdekat dengan kumparan dan paling kecil berada pada jarak terjauh dari kumparan yang tidak terkena pengaruh medan magnet. Jarak terjauh yang masih terpengaruh oleh medan magnet adalah antara 25 s.d 40 cm

Abstract

The working principle of the Maglev train is the interaction between the magnetic poles contained in the train with the magnetic poles that are along the train track. The magnetic poles are made of coils with superconducting wires that are electrified. In theory the magnitude of the magnetic field depends on the amount of current flowing, the core of the coil and the number of turns. In this research, a coil with an iron core of 5 cm in length and 8mm in diameter has 400 turns. Characteristic testing is done by directing the electric current in the coil by varying the amount of current. Measurement of the magnetic field is carried out at a certain distance between 0 to 5 cm with a range of 0.5 cm from the end of the coil. The largest magnetic field is produced at the closest distance to the coil and the smallest is at the farthest distance from the coil that is not affected by the magnetic field. The farthest distance that is still affected by the magnetic field is between 25 to 40 cm

Abstract

Induction motors are widely used in industrial processes, vehicles and automation. Three-phase induction motors can be used for traction systems on electric locomotives. In this case, the speed control system is an important thing that must be applied to the propulsion system. This study aimed to test the indirect torque control for a Three-phase induction motor. A proportional integral (PI) controller was applied for speed controller. The indirect torque control system was modeled and simulated using PSIM software. According to the result, the control method showed a good performance. The speed could be maintained even the speed reference was changing or a load was applied. The steady state error of the speed response was just 0.1% with rise time around 0.06 s. The stator current went up to 39.5 A in starting condition. The stator current reached 12 A rms when the load of 10 Nm was applied. Then, the current rose to 15.7 A rms when the load was increased to 40 Nm and the current came down to 12.8 A rms when the load was decreased to 20 Nm.

Abstract

In the topology of the DC traction substation there is a rectifier component which generally uses a 12 pulse rectifier type and the load is in the form of a trainset with a component in the form of a converter used for variable speed drives (VSD). The operation of the rectifier and the VSD converter load causes harmonics to appear on the AC input side, so anticipation needs to be done. Therefore, it is necessary to conduct an assessment related to DC traction substations to obtain good electrical power quality. The purpose of this study was to determine the electric power quality parameters of DC railway traction using a 12 pulse rectifier and a VSD converter load. This research was conducted by simulating a DC railway traction model with a 12 pulse rectifier and knowing the comparison of the system power quality between the VSD converter load and the resistive load as the basic reference for the traction substation work system of this model. System modeling is done using PSIM software. The results of the simulation are the parameters of the stability of the voltage, current, and system harmonics.
