Abstract

Automatic transfer switches (ATS) have the potential to be important in ensuring uninterruptible power supply across a wide range of sectors, enabling smooth transitions between utility and emergency RES power sources, generators, and more. Utilizing DC electricity provides a cost advantage and is suitable for short-distance transmission. The author proposes a 12-volt DC backup system that corresponds to a minimum input voltage of more than 10 Vdc and can be applied in various DC load applications. The ATS design incorporates multiple inputs and uses algorithms to prevent simultaneous operation of all sources and reduce feedback. These developments in backup system technology, coupled with the shift to renewable energy, are contributing to the creation of a sustainable and resilient electricity grid. In experiments, the ATS system demonstrated its ability to provide 24 hours of backup power with a specified load (lighting bulbs, light-emitting diodes (LEDs), motors, and fans) discharging 0.27–2.25 Amperes. Using the millis programming language, it supports the performance of a constant switch transition speed of around 0.6453 seconds for a switch from buck to SCC. 0.658 seconds for solar charge controller (SCC) to power supply (PSU), 0.656 seconds for PSU to CC PSU, and 0.61 seconds for PSU to OFF.

Abstract

This article discusses the water level control of the tank using PID control which is implemented on PLC (Programmable Logic Control) with HMI interface. This plant system consists of a controlled tank, a sup-ply tank, a water level sensor, a water faucet in the form of a motorized valve, PLC and HMI. In previous studies, the plant system used usually only has a controlled tank without a supply tank so that the control of the system becomes simpler. However, in this study a supply tank was also used so that the flow of water flowing in controlling the water level would depend on the water level of the supply tank and the opening of the water faucet. This plant system with a tank that has an open outlet pipe is a classic system that is non-linear so linearization is needed in its control. In order for the system to be linearized, it is assumed that both the supply tank and the controlled tank only operate within a certain value range. The realiza-tion of a water level control system using a PID controller was made and tested for its effectiveness at the setpoint values of 10 cm and 20 cm. Based on the simulation and experimental results, it was found that the system worked well where the PID control was able to stabilize the system at both setpoint values where the obtained overshoot were below 10%.

Abstract

Abstract- Along with the development of technology, with the inverter you can get temporary electrical energy for several electronic devices using a DC source. In this paper, the designed inverter is a type of 1-phase inverter with an output voltage greater than the input voltage. The inverter uses the SPWM (sinusoidal pulse width modulation) technique, as a switching process. The purpose of this research is to design a single phase full-bridge inverter by adjusting the switching mosfet using DSPF28069M to produce a sinusoidal wave output. A single phase full-bridge inverter is designed by changing the voltage from the battery or power supply from 12-24 VDC to 12-24 VAC. Then the voltage 12-24 VAC is increased by using a step up transformer. The inverter test results of 17 VDC using a 15/220 VAC step up transformer with an efficiency of 81.4%. The results of the SPWM signal with the inverter input 17 VDC, the voltage issued by the inverter is 227 VAC without load, 194 VAC with a load power of 22 Watts, amounting to 178 VAC with a load power of 40 Watts, amounting to 162 VAC with a load power of 88 Watts, and amounting to 154 VAC with a load power of 128 Watts.

Abstract

Abstract— The process of processing household waste into biogas is carried out using fermentation technology. Fermentation technology is the process of decomposition of organic compounds to produce energy and changes in the substrate become new products by microbes. In addition, the fermentation technique that has been done by fermenting household waste produces methane gas content (CH?). To process household waste into biogas is to use biodigester. Biogester is a closed space that is used for the waste fermentation process which is assisted by microbes. Using a biodigester is expected to accelerate the fermentation process of household waste into alternative biogas materials because of the airtight biodigester state. A temperature and pressure data logger tool is designed on smart biogas household waste using the MPX5500DP sensor. The MPX5500DP sensor will detect the amount of gas pressure from the biogas results because the range of readings from this sensor is in accordance with what is needed, while the DHT22 sensor uses a large temperature reading because the temperature in the biodigester is not too large between 28?C - 40?C. From the results of reading the temperature and pressure values, the data will be processed by the Arduino Uno Microcontroller and stored data by the data logger. Based on the test results, the temperature measurement error readings of 0.81%, while for the pressure measurement of about 3.5%.

Abstract

The stability of the robot's performance is very important, especially for the wheeled mobile robots that use swerve drives, which need kinematic control to reach the destination point. The study of robot movement known as kinematics is based on an examination of the geometric structure of the robot, with no consideration given to the mass, force, or acceleration that the robot experiences during movement. This study aims to model and simulate the kinematic control design of a wheeled robot that uses a swerve drive. This robot uses BLDC motor actuator so that the robot can reach its destination very quickly and steadily. The test is carried out by simulating and comparing the performance response using BLDC motors and DC motors. According to the testing and trials, the robot can reach its destination by modeling its kinematic control, and BLDC motors are found to be more reliable and efficient for driving and steering than DC motors.

Abstract

Raya Ngijo Housing, one of the areas in Karangploso in Malang District has a temporary waste management team that organises the collection of waste from residents and sends it to the landfill. The process of collecting waste from residents is usually at the temporary disposal site (TPS) in the form of moving waste from residential cleaning vehicles and accommodated at the TPS until collection by the Malang District environmental service container for disposal to the transferred to landfills (TPA). Problems often occur when the container collection process is delayed for various reasons, so that the amount of rubbish in the TPS is excessive. One of the solutions made by the cleaning team is to burn excess waste and can be burned using a furnace. However, the combustion carried out cannot be ensured perfect combustion which is feared by the environmental service. Therefore, a remote communication-based furnace monitoring system and android application were made to ensure the perfection of the combustion process so that it could be monitored by the cleaning team. Parts per million (PPM) carbon dioxide (CO2) levels of combustion smoke and combustion temperature are also monitored and controlled in accordance with the safe standards set by the environmental agency.

Abstract

The effectiveness of wind and solar energy as electricity generators is significantly impacted by unpredictable and varied environmental circumstances, which affect the output power of the wind-solar hybrid power generation system. So, a control system is required for the optimal power production of hybrid renewable energy systems (HRES). This study delineates optimal power management in wind/solar hybrid energy systems by the application of multi-objective particle swarm optimization (MOPSO) algorithms, inverter controllers, and battery controllers. The MOPSO algorithm enhances power generation by modifying the duty cycle of the direct current (DC)/DC converter based on the output from the wind turbine and photovoltaic (PV) system. The proportional-integral (PI) controller functions as both an inverter and battery controller to ensure the constancy of the DC link voltage and output power. The efficacy of the developed control was evaluated using simulation. A comparison has been conducted between the efficacy of the MOPSO algorithm and the perturb and observe (PO) approach. The simulation findings indicate that the MOPSO algorithm surpasses the PO method for performance and output power. The output power produced by HRES with the MOPSO algorithm exceeds that of the PO approach. Optimal power control utilizing MOPSO can yield optimal power despite fluctuations in wind and solar intensity.

Abstract

Kestabilan daya dan tegangan pada sebuah perangkat elektronik sangatlah penting untuk diperhatikan. Karena jika hal tersebut tidak diperhatikan maka dapat mengakibatkan perangkat elektronik tersebut tidak dapat bekerja dengan maksimal atau bahkan dapat menyebabkan kerusakan pada perangkat tersebut. Seperti halnya drop tegangan power supply pada sebuah mobile robot. Drop tegangan ini dapat mengakibatkan kecepatan dan torsi motor dc pada mobile robot tersebut akan berkurang sehingga hal tersebut dapat menurunkan performa dari mobile robot. Dari permasalahan tersebut, dirancanglah sebuah alat yang ditujukan untuk mengatasi drop tegangan tersebut dengan metode synchronous buck converter yang terdapat controller PID didalamnya. Pada alat ini yang berperan sebagai control utama adalah mikrokontroller STM32 dangan input yaitu sensor tegangan yang digunakan sebagai feedback ketika ada drop tegangan pada output synchronous buck converter tersebut. Dari pembacaan tegangan tersebut mikrokontroller STM32 akan membangkitkan sinyal PWM (Pulse Width Modulation) yang digunkan untuk mengatur durasi on atau off mosfet High-side maupun mosfet Low-side sehingga tegangan output dari synchronous buck converter dapat diatur sesuai dengan set point.
