Abstract

Disturbances in the electrical installation system will be detrimental to electricity users because it can cause power outages. Therefore we need a protection system that can overcome disturbances such as the use of Over Current Relay (OCR). With OCR can overcome interference quickly and can prevent equipment damage. OCR interference occurs if the current read on sensor 1 is more than 10.5 A, then relay 1 will work after a disturbance of 5 seconds. The indicator light on the PLN side will be red. Meanwhile, if the current at sensor 2 is more than 10 A, then relay 2 will work after a disturbance for 5 seconds. The indicator light on the customer side will be red. Short circuit disturbance occurs if the current read on sensor 1 is more than 20.5 A, then relay 1 will work after an interruption of 2 seconds. The indicator light on the PLN side will be red. Meanwhile, if the current on sensor 2 is more than 20 A, then relay 2 will work after a disturbance for 2 seconds. The indicator light on the customer side will be red.

Abstract

Inverter adalah salah satu alat elektronika yang digunakan untuk mengubah tegangan DC (Dirrect Current) menjadi tegangan AC (Alternating Current). Inverter ini diaplikasikan pada pembangkit listrik tenaga floating hydro portable. Gelombang output dari suatu inverter dapat berupa gelombang sinus (sine wave), gelombang kotak (square wave), dan gelombang sinus modifikasi (modified sine wave). Inverter 1 fasa full bridge ini dirancang menggunakan teknik PWM berbasis mikrokontroler Arduino uno, optocoupler sebagai driver 4 MOSFET, transistor 9014 sebagai penguat tegangan inverter, serta rangkaian double boost converter sebagai penaik tegangan pengganti transformator. Inverter ini menggunakan metode mengubah tegangan dari double boost converter 311 Volt DC menjadi 220 Volt AC dengan sumber utama accumulator 12 VDC-35Ah. Tegangan output yang dihasilkan oleh double boost converter sebesar 316 Volt DC. Inverter ini mampu mengubah tegangan 316 Volt DC ke 288,1 Volt AC frekuensi 49,50 Hz dengan gelombang output berbentuk gelombang kotak

Abstract

Technological developments have brought a revolution in the smart home concept, with smart rooms becoming the main focus to increase comfort, efficiency and security. This article explores the concept of a Programmable Logic Controller (PLC) based smart room with Function Block Diagram (FBD) programming. PLCs, which were originally used in industry, were introduced into the smart home environment as a central brain capable of managing and controlling electronic devices. FBD programming, with its visual approach, provides an intuitive programming solution by using function blocks to represent control logic. Through the use of FBD-based PLCs, smart rooms can be effectively automated, including lighting, temperature and security aspects. The advantages of this method include an easy-to-understand programming interface and the ability to design control logic without requiring a deep understanding of programming languages. The research results show that FBD-based PLCs provide an efficient and effective solution to improve the function of smart rooms. This implementation can provide significant benefits in terms of energy management, occupant comfort and home security. Thus, the PLC-based smart room concept with FBD programming marks a step forward in realizing a smart home that is responsive, connected, and can be adapted to the needs of residents.

Abstract

 The uncontrolled and excessive consumption of electrical energy, especially in households, often leads to significant energy waste. This issue adversely affects both consumers and electricity providers such as PLN. To address this problem, a system titled "Centralized Monitoring and Control Based on Load Characteristics Using the Internet of Things (IoT)" was developed. This system is designed to monitor and control household electrical loads in real time. The system consists of a PZEM-004T sensor for measuring voltage, current, power, energy usage, frequency, and power factor. An Arduino microcontroller processes the sensor data, while an ESP32 module transmits the data to an online database. A relay module is used to control electrical devices remotely. The data is stored in a database and visualized through a web-based interface, which also enables users to download monitoring reports in PDF or Excel formats. Testing results showed that the system operates with high accuracy. When compared to a standard power analyzer, the measurement error for parameters such as voltage, current, frequency, and power factor remained low, with a maximum error of only 1.9%. It demonstrates the system’s potential for efficient energy monitoring and management in residential settings.

Abstract

Electrical hazards can occur due to inadequate protection systems, often leading to fires in homes or buildings. One major cause of this issue is users' lack of knowledge regarding standard electrical installations. To overcome this, the Internet of Things (IoT) offers a promising solution by enabling remote and real-time control and monitoring of electrical devices. By integrating IoT technology with home electrical systems, users can enhance safety and manage energy consumption more effectively. A practical implementation involves using a digital kWh meter, which allows accurate measurement of electrical quantities such as current, voltage, power, and power factor (cos Φ) without requiring additional sensors. The system was tested using three household loads: a 5W smartphone charger, a 40W lamp, and a 100W single-phase motor. Monitoring is done through an Android application and a web browser interface, making it accessible and user-friendly. These platforms display real-time electrical parameters and provide estimates of energy costs. Additionally, the system includes a current limitation feature, which is configured by Arduino and can be adjusted through the Android or web interface. This adds an extra layer of protection against overloads, enhancing the safety and efficiency of household electrical usage. The integration of IoT and digital metering contributes significantly to smarter and safer energy management.

Abstract

Small-scale wind turbines often face challenges related to low energy conversion efficiency and the lack of adequate monitoring and automatic protection systems against fluctuating weather and load conditions. This study presents the design and implementation of an Internet of Things (IoT)-based monitoring and protection system for a Small Vertical Axis Wind Turbine (VAWT). The system utilizes Arduino Uno and NodeMCU ESP8266 microcontrollers integrated with INA219, LM35, anemometer, infrared, and DC voltage sensors. Data acquisition and transmission are managed through Wi-Fi communication and displayed on the ThingSpeak web platform for real-time visualization. Experimental testing demonstrated that the system successfully measured and transmitted voltage, current, power, wind speed, temperature, and rotational speed parameters with an average data transmission latency of less than 3 seconds. The protection mechanism activated effectively under simulated abnormal conditions such as over-speed and over-temperature, automatically disconnecting the load to prevent turbine damage. The measurement accuracy for INA219 voltage and current sensors reached ±0.2 V and ±0.05 A, while temperature detection with LM35 had an average deviation of ±0.8 °C. The results indicate that the proposed IoT-based VAWT monitoring system is capable of providing reliable, low-cost, and real-time supervision suitable for small-scale renewable energy applications. Furthermore, it can be used as a learning prototype in vocational education to understand the integration of renewable energy and IoT technologies.
