Abstract

Today the development of electric vehicles is starting to be widely used compared to fossil fuel vehicles, one example is the electric train. An electric train is a train whose propulsion system is an electric motor. An induction motor is an alternating current (AC) electric motor that operates on the basis of induction of the stator's magnetic field into the stator. Here the motor rotor current causes a magnetic field generated by the rotation of the rotor and the stator current. One of the important parameters contained in the vehicle is braking. The regenerative braking method was used in this study where the rotor of the induction motor rotates faster than the stator rotating field so that negative slip occurs and the machine supplies energy. Thus, we need a device that can increase and decrease the voltage of this energy so that it can be stored in the battery. Therefore, in this study the SEPIC topology converter will be used. SEPIC (Single Ended Primary Inductor Converter) is a type of converter that can work step up or step down by setting the duty cycle on the gate switch. By conducting research on the design of the SEPIC converter as a battery charger using PID control which has a function so that the system achieves the desired response, it is hoped that charging can be carried out whose output can match the battery specifications. In this study, software was used to test the system, namely MATLAB/Simulink with the grid frequency as the independent variable. The test results show that the input from the SEPIC converter has varying values such as the voltage above or below 14V. The output of the SEPIC converter voltage has an error and the battery SoC also varies at each grid frequency that supplies the induction motor with a range of 10 Hz – 100 Hz. Keywords: Regenerative Braking, Three-Phase Induction Motor, SEPIC Converter, PID Control, State of Charge (SoC), MATLAB/Simulink

Abstract

The existence of transportation in Indonesia plays a very important role in facilitating human mobility to move from one place to another. The use of electric vehicles is one of the developments that is currently experiencing a lot of progress, including electric trains (KRL). As the name implies, KRL is sourced from electricity which is supplied to the train system, which is mainly used as a motor drive. When using a motorbike, the important parameter to consider is braking. One type of electric braking that is widelydeveloped is regenerative braking. Self-excitation method regenerative braking using a capacitor is one of the branches of regenerative braking. This type of braking uses motor excitation which will be stored in a capacitor. The resulting regeneration energy will be stored in a battery so that it is not wasted as heat alone, therefore to transfer power a DC-DC converter is needed to adjust the battery voltage. The CUK converter is selected to buck/boost the voltage to match the battery specifications. This research was carried out by simulating using Simulink/MATLAB software which is useful for analyzing the input and output of theconverter and the state of charge (SoC) on the battery. Based on the simulation, it shows that the output of the converter produces a voltage of 13.40 V at a grid frequency of 50 Hz with a SoC increase of 0.006426%. The test was carried out over the grid frequency range of 10-100 Hz which resulted in varying voltage errors and SoC increases.Kata Kunci— Things Three Phase Induction Motor, Regenerative Braking, DC-DC Converter, Capacitor, Frequency, State of Charge (SoC)

Abstract

This study describes the effect of variations in ultraviolet light, the silicon rubber coating on the insulator on the level of leakage current and the contact angle, in this study the insulator is made of polyethylene with two variations of angles, namely angles of 120° and 150° where there are two insulators with different conditions, namely coating and no lining. The research method used is to take data on leakage current and contact angle directly at the High Voltage Engineering Laboratory, University of Brawijaya, the test is carried out using AC voltage with a variation of the test voltage of 2 kV, 4 kV, 5 kV, 6 kV, 8 kV, 10 kV , 12 kV, 14 kV, 15 kV, 20 kV and 25 kV. Tests were carried out using 2 conditions for each insulator, namely before and after ultraviolet light irradiation with variations of 12 and 14 hours which were then tested in dry conditions and wet conditions with variations in wetting discharge 10, 30, and 60 mL/s which refers to Rainfall trend in Indonesia. Testing the contact angle on the insulator using irradiation variations of 0, 2, 4, 6, 8, 10, 12, and 14 hours. The results obtained in this study include knowing the level of leakage current in each insulator, especially comparing dry conditions and the presence of wet conditions with an increase in wetting discharge so that the surface resistance is known and also the power loss caused by the insulator. The results obtained from this study include the addition of coating causing an increase in the contact angle and the size of the leak and the greater the addition of the fin angle will cause an increase in the leakage current level, besides that the wetting current discharge also affects the leakage current, where the increase in the insulator leakage current level is directly proportional with the addition of wetting discharge.

Abstract

The propulsion system for the fast train in this study uses a three-phase induction motor.The weakness of the induction motor lies in speed control.By using the direct torque control (DTC) method it can be overcome, but this method causes ripples in the output. Therefore, in the DTC method there is an on-of controller which will be set to suppress the ripple value. Setting is done on the value of the on-of switch contained in the flux and torque hysteresis controller to determine the ef ect of varying the hysteresis width on the on-of controller on decreasing ripple. In addition, the execution time is also added to the simulation series in order to determine the ef ect on the DTC method.The result of this study is that the ripple percentage value can be reduced by setting the flux hysteresis controller, which is from 18.238% to 6.330%. Then, with the settings on the torque hysteresis controller can also be reduced, which is from 6.330% to 6.231%. While the addition of execution time on the simulation, the ef ect is directly proportional to the ripple width of the output torque graph.

Abstract

In this study, an analysis was carried out on the design of the PI controller and feedforward control to reduce the influence of interference due to load torque. Feedforward control works by detecting disturbance or called interference then the magnitude of interference will be compensated by the feedforward controller so that interference is reduced and does not interfere with the output value set by the set point. The determination of Kp and Ki controller parameters is carried out using the optimum symmetrical method and the value of the controller parameters Kp = 11.752 and Ki = 0.42 is obtained.

Abstract

This research explains the rectifier system in a train propulsion system that uses a capacitor as a filter (referred to as a DC link capacitor), which generally has a large capacitance and requires the addition of a power decoupling circuit to assist the capacitor in energy storage. The power decoupling circuit is connected in parallel between the rectifier system and the load side, and the topology used is a buck-boost type. The circuit consists of several components such as capacitors, inductors, and switch components (MOSFETs). The objective of this research is to obtain a small capacitance value for the DC link capacitor by using a power decoupling circuit. Testing is carried out using Simulink software in MATLAB as a simulation tool to control the power decoupling circuit and enable energy storage. In this research, testing is also conducted on the rectifier system without using the power decoupling circuit to determine the comparison of capacitor capacitance values used between the two systems. The results obtained in this study are as follows: for the system without using a power decoupling circuit, it requires a DC link capacitor of 70 µF. On the other hand, the system that uses a power decoupling circuit requires a DC link capacitor of 2 µF, with the same resistive load of 100 Ω. This is achieved by adding a decoupling capacitor of 10 µF and a decoupling inductor of 1mH in the power decoupling circuit. Keywords: Performance, Buck-Boost Power Decoupling, Capacitor, Propulsion System.

Abstract

Yogurt is a food product that is widely consumed. The manufacturing process is by mixing the Lactobacillus bulgaricus and Streptococcus thermophilus bacteria into milk and proceed with the incubation stage. In the incubation process, the temperature of the milk must be carefully maintained with a normal time of around 16 hours in order to produce a good product. This makes yogurt producers quite difficult because they still use manual methods. Therefore, a water temperature control tool was made in this yogurt incubation process. This tool works by placing milk that has been treated with bacteria in a container surrounded by water. The water temperature will be maintained so that the temperature of the yogurt is maintained. Temperature control is carried out using the PI control method to make it easier for yogurt producers to carry out the production process. The ziegler-nichols method is used to obtain Kp and Ki parameters. Based on the test results, the PI control can control the water temperature well with the parameters Kp = 49.87 and Ki = 0.033. The response of the testing system for controlling water temperature in the yogurt incubation process with a yoghurt temperature setpoint of 45°C obtained that the water temperature reached steady state at 12771 seconds with an overshoot of 4.8% and a steady state error of 1.6%. For the yogurt temperature value to reach steady state occurs in the 6594th second with a steady state error of 4.1%. In the yogurt incubation process which lasted for ± 10 hours, it was found that the temperature difference between the water and yogurt was an average of 1.63°C.

Abstract

Microhydro Power Plant (MHPP) is a small-scale power plant that is environmentally friendly which utilizes the existing water discharge around us to be converted into electrical energy such as irrigation canals or rivers. Because the small-scale MHPP tends to use synchronous generators which are relatively affordable. When a synchronous generator is subjected to a load of varying magnitude, the magnitude of the voltage will also vary. This causes voltage and frequency instability in the MHPP. This study will use MHPP Andungbiru Unit A2, Tiris District, Probolinggo Regency as a test object with a descriptive research type through a quantitative approach which aims to provide an overview of the voltage and frequency instability that occurs. The results of this study indicate that the highest/lowest voltage and frequency instability values, namely 274.6 volts/53 Hz and 118.5 volts/27.67 Hz, are due to the influence of changes in load current. This can cause the generator rotational speed to fluctuate, causing the resulting voltage and frequency to become unstable. The solution is to add water power to rotate the turbine shaft and rotate the generator faster so that it can reduce the value of the voltage drop caused by losses on the turbine and generator parts. This is because large electric power can increase the voltage and frequency without having to adjust the load. Additional water power can be done by making improvements to civil parts so that they comply with standardization. In addition, improvements to the electrical part, namely improvements to the ELC system, can also be used to achieve stable and more efficient voltage and frequency values.
