Abstract

The air distribution process is still using the manual method, namely by using human power to activate and deactivate the distribution pump and use the average demand graph as a reference. This results in irregular air distribution. Therefore we need a control system on the distribution of the pump that can work automatically to maintain air distribution according to the level of customer needs. One of the most important parts of a water pump is the drive in the form of an electric motor. One type of electric motor that can be used is a BLDC motor. The BLDC (Brushless Direct Current) motor is a development of the DC motor, where in the commutation process it uses electronic commutation so that there are no mechanical problems, and interactions. The use of a BLDC motor requires a control system to regulate its speed. One of the methods that can be used is using a PID controller. PID can improve motor response by producing a fast and smooth response and small overshoot, but the PID controller cannot be applied to non-linear loads, while BLDC motors have a multi-variable, non-linear system, and can easily be affected by parameter variations and disturbances. If this controller is still applied then the system response to stable conditions will be quite long and cause the motor to have poor performance. In this study, a controller was developed by combining PID controller with Fuzzy Logic Control. Fuzzy logic control produces additional parameters for each PID parameter controller. Variations of the FLC output make thecontroller implicitly adjustable. It is hoped that in this study, a response system will be obtained that has a high steady state level with a fast settling time.Keywords: BLDC Motor, PID Controller, Fuzzy Logic Control, Steady State

Abstract

Air pollution from motor vehicle fumes has become a big problem for the environment. The existence of electric vehicles is an effort to reduce the problem of air pollution. However, electric vehicles that use battery resources have a weakness in battery lifetime. To overcome this, we need a system where the battery life when used so as not to run out quickly, namely with a regenerative braking system. Simulation of the regenerative braking system for controlling a DC motor based on fuzzy-PID auto-tuning is a simulation of the regenerative braking system using a bidirectional DC-DC converter and controlling it using auto-tuning fuzzy-PID. This system simulation aims to obtain appropriate control with the system and determine changes in the SOC value of the battery from the resulting regenerative braking. From the system simulation results, it can be seen that the actual speed of the DC motor and changes in the SOC value of the battery can be seen by knowing the value of the performance parameters of the controls made. Index Terms— electric vehicle, regenerative braking, bidirectional dc-dc converter, DC motor, auto-tuning fuzzy-

Abstract

Solar energy is energy that comes from the sun and has great potential to be utilized, one of which is to make electricity. In line with the target of a 23% renewable energy mix in Indonesia through the National Energy General Plan (RUEN), solar energy is one of the main renewable energies to be developed through solar panels. This is intended as one of the efforts to reduce Green House Gas (GHG) emissions, achieve energy independence in the future, and form an energy source at an affordable cost. The Electrical Engineering Joint Building of Brawijaya University (GBTE UB) is one of the buildings in the UB campus which will be the object of research in this study. The purpose of this study is to determine the feasibility of installing an on-grid rooftop Solar Power Plant (PLTS). This study was conducted by reviewing the feasibility of installation from two aspects, namely technical and economic aspects. There is several software needed in this study which include: Helioscope, PVSyst 7.2, and ETAP. Helioscope and PVSyst 7.2 are useful in determining the correct type of components and simulating various types of plotting available. Based on the simulation, it was found that 46 Trina Solar TSM-PE14A 320 Wp modules and an inverter with a capacity of 12 kW would give a Performance Ratio (PR) value of 80.7% and a DC/AC ratio of 1.23. The total power produced by PV system is 14,72 kWp and energy produced is more than 18 MWh annually will be supplied to the load at GBTE UB. ETAP 16.0 is used to determine the power distribution in the system. It is noted that the load at GBTE UB uses 15,1 kVA and still needs 8,14 kVA power supply from PLN. Economically, the initial investment required to install a PLTS on-grid is IDR 208,619,628 with a net metering scheme of 1:1. Therefore by this scheme, all surplus energy produced by the PV system might be able to be exported to PLN grid 100%. The simulation shows that the NPV is 256.265.384 IDR, IRR is 19%, PP is 6,45 tahun, and PI is 31,04. Based on the feasibility study, the PLTS system was successfully assessed as feasible to implement as an effort to accelerate renewable energy in Indonesia.

Abstract

This study describes the effect of variations in the sleeve fins on polyethylene insulators on the level of leakage current and flashover voltage in dry and wet conditions. This research begins with data collection by testing the leakage current and breakdown voltage at the High Voltage Laboratory, Department of Electrical Engineering, Faculty of Engineering, Universitas Brawijaya. The various conditions used in testing the leakage current and flashover voltage include dry conditions and wet conditions with different wetting rates, namely 10 mL/s, 30 mL/s, and 60 mL/s. Tests were carried out using high AC voltage on three types of insulators, namely type A, type B, and type C. The arrangement of the electrodes used was rods. The results obtained in this study are the influence of the variation of the fin arm on the level of leakage current and flashover voltage. Where the insulator that has the lowest level of leakage current is the type B insulator with the size of the upper fin which is longer than the lower fin. This is influenced by the upper fin of the insulator which resembles a hood, which when wet conditions cause the water not to completely hit the lower fin. Where the greater the value of the wetting discharge, the greater the value of the leakage current and the greater the surface resistance and power losses. This type B isolator has the best resistance because it also experiences flashover at the highest test voltage level.

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.

Abstract

Geographically, Indonesia is located on the equator which is always exposed to sunlight throughout the year, so solar energy has great potential to be developed. In general, there are two technologies that utilize solar energy, which is photovoltaic (PV) technology and solar thermal technology. The main problem of photovoltaic systems is the low efficiency of the electricity produced. To maximize the work of photovoltaic (PV) can be obtained through the Maximum Power Point Tracking (MPPT). One of them is MPPT perturb & observe (P&O). The increase in radiation intensity is proportional to the output power. When the radiation intensity is high, the temperature also increases. When the temperature increases, the efficiency of photovoltaic will decrease. In this study, a cooling system was designed that uses water at MPPT perturb & observe (P&O) with a converter used is a boost converter. The results of this study prove that a decrease in the temperature of solar panels by 21.190C can increase the power generated by 8.748%. keywords─ Photovoltaic, MPPT, Perturb & Observe, Boost Converter, cooling system.

Abstract

Micro hydro power plants (PLTMH) have the potential as an alternative source of electrical energy, especially in rural areas or remote areas that have abundant air potential. However, the PLTMH also has a problem, namely the electric power which produces a small connection with the distance of the generator is far from the point of load so that problems such as power lossand voltage drop arise so that it is necessary to do a power loss analysis to find out the condition of the power loss and voltage drop to increase the reliability of the system by This research was conducted at the Andungbiru Village PLTMH, Tiris District, Probolinggo. With power loss analysis using the Newton Raphson method, using Matlab software to obtain a large channelpower loss value and efficiency using the Newton Raphson method with an R phase of 918.21 Watt with an efficiency of 61.54%. The S phase is 1098.40 Watt with an efficiency of 55.76%. Phase T is 1073.5 Watt, with an efficiency of 57.14%.
