Abstract

Studi kontingensi system tenaga adalah hal yang sangat penting, karena sistem harus dirancang dan dioperasikan sehingga apabila terjadi kontingensi (N-1) atau lepasnya suatu elemen sistem baik generator maupun saluran transmisi tidak akan mengalami kehilangan beban. Penelitian tentang analisis kontingensi N-1 pada sistem tenaga listrik perlu dilakukan, karena memiliki karakteristik yang berbeda dengan kondisi saat sistem beroperasi secara normal. Ketidakstabilan sistem Sulselrabar dalam kondisi normal akan menjadi acuan bagi peneliti untuk membahas kondisi sistem saat sistem tidak beroperasi secara normal seperti kontingensi N-1. Analisis kontingensi N-1 di sini berada di tengah-tengah garis Sidrap-Maros. Garis tengah Sidrap-Maros adalah garis yang menghubungkan daerah-daerah pusat beban. Salah satu metode yang diusulkan disini adalah penambahan Dual Input Power System Stabilizer (DIPPS). Dari hasil simulasi didapatkan kinerja sistem Sulselrabar saat kontingensi N-1 lebih optimal dengan menggunakan DIPSS, hal tersebut ditinjau dari karakteristik osilasi kecepatan generator yang minimum, deviasi respon sudut rotor yang baik, serta nilai eigenvalue yang semakin negatif. Untuk membandingkan kinerja sistem yang diusulkan, digunakan PSS konvensional dengan satu input.

Abstract

Farmers in the hamlet of Borong Rappo, Sokkolia Village, Bontomarannu District, Gowa Regency with an area of 10 ha of rice fields. In the dry season, water for irrigation is obtained from wells or reservoirs. For water to be channeled to the fields, the water in the well or reservoir is pumped using a pump machine. There are two types of pump machines used by farmers, namely machines with petalite fuel and those using gas, thereby increasing production costs. This activity aims to help farmers reduce operational costs in the form of fuel costs by implementing a Solar photovoltaic water pumping system (SPVWPS). SPVWPS has almost 0 (zero) operational costs. The procedure for implementing this PKM activity begins with a site survey and discussions with partners to determine solutions to problems. The types of SPVWPS implemented are direct driven type and deep well (submersible) pump type. The implemented SPVWPS capacity is 900 Wp for solar panels and 700 W for DC pumps. The results of observations of pump performance in sunny conditions the pump can produce a discharge of 84.1 l/minute so it takes about 2.77 hours to meet the water needs of each paddy field. While in cloudy conditions this SPTAS can pump 53.3 l/minute of water, in this condition it takes 4.38 hours to meet water needs. The SPTAS system can eliminate pump operating costs and the average time needed to meet water needs each day is 3.75 hours.

Abstract

Batteries are components that supply, provide and distribute electrical energy in various electronic devices. Still, there are times when the battery must be recharged because the battery has a high energy storage ratio but has limited power. Another component that functions like a battery is a supercapacitor which can store a large charge of energy that can be used to help battery performance. This study aimed to analyze the impact of installing supercapacitors on batteries operating in solar power plants by varying the number of supercapacitors connected to batteries. The methods used in this research are literature study, design method, manufacturing method, testing method, and data analysis method. Based on the test results, it was found that the installation of 4 capacitors has optimal performance, with an average current consumption of 0.18877551 Ampere. For three capacitors, the average current is 0.203552632 Ampere. For two capacitors, the average current is 0.205517241 Ampere. As for the power characteristics, for four capacitors, the average power is 31.81632653 watts. With three capacitors, the average power is 34.36447368 Watt, and with two capacitors, 34.71724138 Watt.

Abstract

Solar Home System is one of the technologies for utilizing solar power at home. To optimize the performance of PLTS, it is necessary to regulate the use of electrical energy. In this research, an effort is made to control the load using fuzzy logic to regulate the power consumption used by the load so that energy can be utilized effectively. The fuzzy logic method works based on the input given so that the desired results can be as expected. To test the effectiveness of the fuzzy logic method, this study was tested with two types of loads: lighting and fan loads. For lighting loads, it uses two light sensor inputs, and for air conditioning, it uses two temperature sensor inputs and a PIR sensor. The test results show that in the experiment of setting the light load using fuzzy logic, the average power usage at the load is 11.31 watts. In contrast, without fuzzy logic, the average power usage value for the load is 14.29 watts. In the fan load control experiment using fuzzy logic, the energy consumption setting was obtained according to the room temperature input and the number of people in the room. The test results received power usage without using fuzzy logic, where the average fan power usage value is 4.32 Watts, while without fuzzy logic, the average power usage value is 2.97 Watts. For one sensor input, the average power usage value of the average fan is 3.02 Watts; without fuzzy logic, the average power usage value is 2.93 Watts for two sensor inputs.

Abstract

The potential wind speed in Indonesia is generally low at 3 m/s to 7 m/s so that this type of vertical axis turbine is considered very suitable for use in wind conditions in Indonesia. There are several types of vertical axis wind turbines. One type of vertical axis wind turbine is the Savonius wind turbine. Many advantages that this type of wind turbine has, such as being able to receive wind from all directions, easy and cheap to manufacture, and can rotate at a fairly low angular speed. This test was carried out to determine the performance of conventional and modified savonius turbines with 2 and 3 blades variables in each turbine blade shape. The form of modification made is by changing the shape of the blade twisting by 45o. The turbine is carried out on a laboratory scale with a wind source using a fan that is directly opposite the turbine. The results showed that the highest turbine power occurred in a modified 2-blade turbine, namely 1.88 Watt with a torque value of 0.04 Nm and a shaft rotation of 450 rpm. The highest rotation value is also obtained by 2 modified blades at a wind speed of 6 m/s producing 896 rpm. However, the highest torque value is obtained by a conventional 2-blade turbine with a value of 0.136 Nm. The highest turbine efficiency in each turbine is obtained by a modified 2 blade turbine with an efficiency value of 36.92% while the highest turbine efficiency for a modified 3 blade turbine reaches 11.69% which is considered less efficient than other turbines.

Abstract

Wind Power Generation (WPG) requires specific wind conditions to generate electrical energy. Indonesia's wind potential enables the development of small-scale power plants. Innovations in windmill technology need to be developed to ensure maximum results in low wind speed conditions. This research proposes the design and implementation of WPG using a vertical axis to provide lighting for pond houses. The goal is to benefit pond workers in coastal areas that lack electricity from the National Electric Company. The manufacturing stages include design and testing. Based on the design results, the dimensions of the propeller area are 0.393m, the frame height is 1.5m, and the wind turbine height is 0.75m. The performance test of the WPG yielded the highest turbine power value at 15.30 WITA, with a turbine power output of 25.38 Watts.

Abstract

Generator instability, which manifests as oscillations in frequency and rotor angle, is brought on by sudden disruptions in the power supply. Power System Stabilizer (PSS) and Energy Storage are additional controllers that enhance generator stability. Energy storage types include superconducting magnetic (SMES) and capacitive (CES) storage. If the correct settings are employed, PSS, SMES, and CES coordination can boost system performance. It is necessary to use accurate and effective PSS, SMES, and CES tuning techniques. Artificial intelligence techniques can replace traditional trial-and-error tuning techniques and assist in adjusting controller parameters. According to this study, the PSS, SMES, and CES parameters can be optimized using a method based on particle swarm optimization (PSO). Based on the investigation's findings, PSO executes quick and accurate calculations in the fifth iteration with a fitness function value of 0.007813. The PSO aims to reduce the integral time absolute error (ITAE). With the addition of a load-shedding instance, the case study utilized the Single Machine Infinite Bus (SMIB) technology. The frequency response and rotor angle of the SMIB system are shown via time domain simulation. The analysis's findings demonstrate that the controller combination can offer stability, reducing overshoot oscillations and enabling quick settling times.

Abstract

To maintain the reliability of the plant so that it continues to operate optimally, therefore the company management has arranged several scheduled maintenance activities. The result of the delay in maintenance had an impact on some equipment so that it suffered fatal damage. One of the mechanical problems that occur in PLTA BAKARU is water leakage that occurs in the guide vane. At the PLTA Bakaru unit, the impact of this guide vane leak can cause the generator to trip with an indication of 133 QBL and require the unit to leave the concession for some time. Thus the result of the disturbance becomes a loss for the company because it cannot produce electricity. From the results of the analysis, it was found that the amount of water needed to generate 1 kwh in unit 1 of PLTA Bakaru was 0.000295 m3 / s, the amount of energy loss caused by leaks in the guide vane was 121,975,031 kWh in 2015; 41,933.26 kWh in 2016; 135,591.42 kWh in 2017; and 518,637.17 kWh in 2018, power losses also occurred in the use of pumps for handling leakages of 75 kW. the amount of water consumption continued to increase from 2015 to 2018 before the overhaull and after overhaul maintenance the SWC value decreased to 0.29365 at 63 MW unit load operations.

Abstract

This research proposes an additional controller for load frequency control at a micro hydro power plant using PID-SMES. The PID-SMES parameters are optimized using smart methods called Ant Colony Optimization (ACO), which could find the optimal value of PID-SMES. In this paper four control approaches are compared which are P, PI, PID, SMES, and PID-SMES. From the simulation results, it can be obtained that overshoot of P controller is -0.0002193, with PI Controller is -0.0002183, with PD Controller is -0.0002139, with PID controller is -0.0002129, with SMES controller is -0.0001958, and with PID-SMES is -4.187e-05. ACO optimization results obtained fitness function value of 7.15e-09, with 50 iterations. The minimum value of the system performance function at each iteration is plotted on the convergence graph. In the simulation result, it can be concluded that the ACO algorithm could be quickly convergence on the 14th iteration or find the most optimal value at the 9th iteration. The PID-SMES controller proposed in this study has a significant influence in the damping of the oscillation of frequency deviation. Therefore, PID-SMES is appropriate to be applied to micro-hydro power plant.
