Abstract

The unbalanced load in electric power distribution system always happen and it is caused by single phase loads on low voltage system. The effect of the unbalanced load is appear as a neutral current. These neutral current cause losses, those are losses caused by neutral current in neutral conductor on distribution transformers and losses caused by neutral current flows to ground. In conclusion, when high unbalanced load happened, then the neutral current that appear is also high.

Abstract

A modern control of electric motor’s speed in an industry  needs a variable direct voltage. The variable direct voltage can be supplied by semiconductor devices such as SCR. The output voltage of a SCR rectifier depends on the delay angle of the SCR. The aim of this research is to make a SCR rectifier circuit and applying it for observing the characteristics of a shunt direct current motor. The result shows the circuit can work to demonstrate the shunt motor characteristics.   Keywords : Rectifier ciscuit, Three phases, Shunt motor, Characteristics.

Abstract

Renewable energy is an energy source that can be utilized continuously and is available by nature. One example of using renewable energy is photovoltaic. Photovoltaic is a tool used to absorb solar energy and convert it into electrical energy using the photovoltaic effect method. This research aims to monitor the salinity (salt content) of sea water by utilizing solar energy using the Buck Converter type DC to DC Converter method to regulate and reduce the higher voltage to a lower voltage to be loaded on the microcontroller as the reading output. This research was designed using a 20 WP photovoltaic with a maximum voltage of 20 volts which functions as a power supplier or energy source whose voltage is then reduced by a buck converter circuit to a smaller voltage of 5 volts to be charged to the Arduino Uno in processing salinity measurement data using a TDS sensor. as a measuring tool. The test results of the equipment show that the DC to DC Converter circuit is successful in reducing the photovoltaic voltage so that it can operate the microcontroller.

Abstract

Hydropower plants (PLTA), micro-hydro plants (PLTMH), and pico-hydro plants (PLTPH) in Indonesia use generators with excitation systems to generate fields or magnetic field amplifiers. The use of excitation systems in generators has several drawbacks. In the era of technological development, various types of generators have been developed, one of which is the permanent magnet generator. The Permanent Magnet Synchronous Generator (PMSG) has separate excitation from the synchronous generator and is carried out by permanent magnets to generate the magnetic field instead of coils. This research aims to explore the potential of irrigation channels being utilized as PLTPH using permanent magnet generators. The research method used is the experimental method. The experimental research method is a true experimental method where the equipment is tested and examined. Experimentation involves observation under artificial conditions, where these conditions are created and controlled by the researcher. This study shows that the irrigation channel in Porame Village has the potential to be used as a Pico-Hydro Power Plant (PLTPH) to provide electrical energy as an alternative lighting source, especially at night and during power outages from the national electricity grid (PLN). From the measurement and calculation results, the water flow rate at night is 0.3835 m³/s, with the water power being Pair = 1,901 watts. The type of turbine used is a crossflow turbine, utilizing a permanent magnet synchronous generator.

Abstract

The predictive torque control (PTC) technique of electric motor drive is based on the principle that the determined optimum voltage vector will be applied to the motor in the next cycle. If a three-phase inverter is used, this inverter can only realize eight different switching states. One of the eight switching states is used as the optimum inverter switching state for the next cycle. PTC with one-step prediction cannot obtain an experimental motor speed control, because in the real-time implementation, there is a single sampling delay between input and optimal actuation due to a large number of real time calculations. The delay time problem could be solved by modifying the optimization steps by using the two-step prediction of PTC model. The experimental results show that the motor can follow the reference speed and command torque in the step response and variable speed experiments. In variable speed experiment, good speed and torque dynamics can be achieved by selecting the proportional gain value that corresponds to the motor speed

Abstract

A solar tracker is a photovoltaic (PV) system support tool aimed at optimizing solar energy absorption by directing solar cells to follow the movement of the sun.In this research, a solar tracker for PV with battery load model was created using MATLAB-Simulink with each controller, namely Proportional Integral (PI), Proportional Derivative (PD) and Proportional Integral Derivative (PID) and the simulation results were compared. The simulation results show that the PID controller is the controller with the most optimal results because all set point values ​​entered in the output remain the same and the overshoot value is also low, the PD controller is the controller that produces high errors and also overshot reaching 120 V, and the PI controller is the controller that the results are closest to a PID controller where the resulting overshoot value is only around 20%.
