Abstract

Solar Power Plants (PLTS) are an efficient renewable energy solution for providing electricity, especially in areas not covered by conventional power grids. This study aims to analyze the PLTS system as a power supply for submersible water pumps, focusing on energy efficiency, voltage stability, and system reliability under various operating conditions. The research methodology includes experimental analysis and simulation using a quantitative approach. Data were obtained through direct measurements on a PLTS system consisting of solar panels, a power controller, batteries, and an inverter as the power source for the submersible water pump. The analyzed variables include solar panel output power, battery charging efficiency, and pump performance under different weather conditions and workload scenarios. The results showed that the PLTS system could provide sufficient power to operate the submersible water pump with an average efficiency of XX%. The voltage stability generated by the inverter remained within the appropriate range for pump operation, with minimal fluctuations under maximum load conditions. However, reduced sunlight intensity during cloudy and rainy conditions led to decreased power output, affecting pump performance. To enhance system reliability, it is recommended to use batteries with larger capacity and a smart control system for optimized power distribution. In conclusion, the PLTS system can serve as an effective and environmentally friendly power source for submersible water pumps. However, further optimization is needed to ensure stable performance under various weather conditions.

Abstract

Brushless DC (BLDC) motors are widely used in various industrial applications due to their high efficiency and ability to produce large torque. However, controlling BLDC motors often requires rotor position sensors, which increases the cost, complexity, and risk of system failure. Sensorless control methods have become an alternative solution by utilizing electrical parameters such as back electromotive force (back-EMF) for rotor position estimation, eliminating the need for physical sensors. This study aims to study and simulate a sensorless control system for a BLDC motor using MATLAB Simulink software. This approach integrates a back-EMF detection algorithm with hysteresis control to ensure commutation stability at variable speeds. Simulation results show that this method is capable of producing accurate and responsive control to changes in load and speed, with higher energy efficiency compared to sensor-based methods. This study makes a significant contribution to the development of more economical, reliable, and effective BLDC control technology. This model-based simulation also offers important insights into the development of BLDC motor control systems for practical applications in various fields. Further research can be focused on the implementation of the system on hardware to validate the simulation results.

Abstract

Sistem transmisi daya listrik tegangan tinggi, seperti saluran 275 kV, memainkan peran krusial dalam menjamin penyaluran energi yang efisien dan andal dari pembangkit ke konsumen. Namun, kompleksitas operasional jaringan sering kali menyebabkan fenomena jatuh tegangan (voltage drop ) dan rugi-rugi daya (power losses ), yang berpotensi mengganggu stabilitas sistem, terutama pada konfigurasi multi-bus. Penelitian ini bertujuan menganalisis pola jatuh tegangan dan rugi-rugi daya pada saluran transmisi 275 kV dengan konfigurasi 5 bus menggunakan simulasi MATLAB. Analisis dilakukan melalui load flow analysis berbasis metode Newton-Raphson untuk mengevaluasi profil tegangan, rugi-rugi daya aktif/reaktif, serta dampak variasi beban pada stabilitas sistem. Simulasi mencakup tiga skenario: beban normal, peningkatan beban 25%, dan peningkatan beban 50%. Hasil menunjukkan bahwa jatuh tegangan (voltage drop) meningkat seiring peningkatan beban, dengan penurunan tegangan tertinggi terjadi pada Bus 5. Pada skenario peningkatan beban 50%, tegangan pada Bus 5 mencapai 0.950 pu (jatuh tegangan 5%) , yang merupakan batas bawah toleransi operasi standar (±5%). Rugi-rugi daya aktif juga meningkat signifikan dari 6.11 MW (beban normal) menjadi 13.28 MW (peningkatan beban 50%) , atau peningkatan sebesar 117% , sesuai dengan teori Ploss​=I2R. Rugi-rugi daya reaktif berubah dari negatif (-10.81 Mvar) menjadi positif (+11.32 Mvar), menunjukkan dominasi efek kapasitansi shunt pada beban tinggi.

Abstract

In the utilization of Radio Repeater communication, electrical energy is needed to supply the radio so that communication can always run well. The problem is that there are frequent power outages that disrupt information activities via radio communication. Frequent power outages from PLN cause the Radio Repeater to be inactive so that communication is cut off. Therefore, in this study, a Solar Power Plant (PLTS) is utilized as a power supply for the Radio Repeater at PT. Icon Plus Pekanbaru to be able to operate non-stop and be able to survive for at least 3 days without sunlight. The maximum power generated by the solar panel is 6 panels x 100 Watt = 600 Watt. The amount of energy generated = The amount of power generated (watts) x Peak Sun Hours (hours) or Wh = 600 x 4 = 2400. The radio repeater operating time is 10 hours per day. Two 40 watt lighting lamps operate with the assumption that the condition is on for 13 hours per day. The lights are on from 6 pm to 7 am. Radio Load = Current Consumption (A) x Usage Time (hour) x System Voltage (V), Active Radio = 6 x 10 x 12 = 1440, Radio on standby = 1.5 x 12 = 864, Lighting = 13 x 40 = 520. then the difference between production energy and used energy is 1920 Wh - 1672 Wh = 248 Wh. With a configuration of two 200 Ah batteries in parallel with a DoD assumption of 50%, the Days of Autonomy can be calculated by ((50% x 600 x 12) + 248 Wh) / 1672 Wh = 2.3 days

Abstract

The development of renewable energy technology increases the need for efficient and reliable inverters to convert direct current into alternating current. This study aims to analyze the performance of a pure sine wave inverter using the EGS002 module as a pulse width modulation controller to produce a pure sine wave. The main issues studied are power conversion efficiency, output voltage stability, and total harmonic distortion (THD) under various load conditions, including resistive and non-linear loads. The research method involves experimental simulations using MATLAB/Simulink and Proteus software, by designing an inverter system based on the EGS002 module, IRF3205 MOSFET transistor, and LC filter. Performance parameters measured include power conversion efficiency (η), total harmonic distortion, and RMS output voltage (V_RMS). The simulation results show that the inverter achieves an average power conversion efficiency of 91.4%, total harmonic distortion below 5% under all load conditions, and output voltage stability with a deviation of less than 1% from the nominal value of 220 volts. These findings indicate that the EGS002 module is effective for inverter applications in renewable energy systems, although optimization is required for non-linear loads and production cost reduction. This research provides important insights for the development of more efficient and reliable inverters.
