Abstract

This research explores the use of a Governor as a frequency control mechanism in a power generation system by implementing two control methods: Proportional-Integral (PI) Controller and Fuzzy Logic Controller (FLC). The objective of the study is to evaluate the dynamic frequency response of the system and compare the performance of both control methods against the permissible standard, which is within the range of 50±2% (49 Hz to 51 Hz). Through simulations of a power generation system, parameters were adjusted to achieve the target frequency, and both control methods were evaluated. The results indicate that both methods can maintain the frequency within the desired range. However, Fuzzy Logic Controller on the Governor produces a superior dynamic frequency response with a lower steady-state error percentage. The implementation of Fuzzy Logic Controller also demonstrates a faster time to reach steady state compared to the PI Controller method. This superiority suggests that FLC provides more adaptive and responsive control to load fluctuations, enhancing the efficiency and stability of the power generation system.This research provides deeper insights into optimizing frequency control on Governors, particularly through the use of Fuzzy Logic Controller. Consequently, the development of this technology has the potential to improve the performance and reliability of power generation systems, supporting the transition towards a more efficient and sustainable electric grid.

Utilizing the ETAP simulation software, we evaluated the distribution of power, currents, and power factor across the entire system. The results of the analysis provide deep insights into the system's response to loads, power flow, and the efficiency of electrical power utilization. At the 345 KV voltage level, the simulation demonstrates the system's capability to maintain stability and power balance effectively. Power distribution and currents among generators provide a clear overview of the performance of the electrical network. Power factor analysis offers additional information regarding the efficiency of electrical power usage within the system. These findings serve as a crucial foundation for making informed decisions in managing and developing renewable energy infrastructure. In the era of transitioning towards more sustainable energy sources, a comprehensive understanding of power flow and system responsiveness to loads is essential to ensure the reliability and efficiency of the electrical power system

Abstract

A real-time monitoring and control system for Neutral Grounding Resistor (NGR) has been developed utilizing Internet of Things (IoT) technology. The system employs the PZEM-004T sensor for measuring current and voltage, and the NodeMCU ESP8266 for data processing and communication. Measurement data is displayed in real-time on an LCD screen and a website, with early warning alerts provided through a buzzer/alarm if abnormal conditions are detected. This system addresses the limitations of traditional monitoring methods, which are typically visual and periodic, by enabling continuous monitoring. Integration with a circuit breaker adds an additional layer of protection by disconnecting the power supply when necessary. Testing results demonstrate the effectiveness of the device in measuring voltages ranging from 5V to 220V and current, with a reliance on internet connectivity to ensure measurement accuracy. This system offers an efficient and proactive solution for maintaining the safety and reliability of electrical equipment at substations

Abstract

This study aims to develop an Internet of Things (IoT)-based electrical load control system that can improve energy consumption efficiency in households. The system utilizes the Blynk application connected to relays and current sensors to monitor and control electricity usage in real-time. The research compares the system with and without the use of a repeater to assess its impact on response time. The results show that the use of a repeater reduced the communication response time between the devices and the application from 4.2 seconds to 2.8 seconds. This reduction in response time allows the system to optimize load management more quickly and efficiently. Additionally, the system has the potential to reduce energy waste, lower electricity costs, and support efforts to reduce carbon emissions through better energy management. However, challenges include the initial investment costs, device compatibility, and data security issues, which need to be addressed for wider implementation in Indonesia. With further development, this system holds great potential in supporting energy sustainability and household efficiency.

Abstract

The Internet of Things (IoT)-based current monitoring and protection system is an innovative solution for real-time measurement and control of electrical parameters. This study aims to analyze the accuracy of voltage, current, and power readings using the INA19 sensor connected to the Telegram application and compare the measurement results with conventional calculation methods. Testing was conducted by varying the voltage from 150V to 225V using a variac, and the data were compared between smartphone readings, multimeter measurements, and manual calculations. The results indicate that the smartphone-based monitoring system has a high level of accuracy, with a maximum voltage error of 0.93% and a current error of 0.63%. However, at certain test points, the power error percentage fluctuated significantly, reaching 99.22% at 195V. Additionally, the relay-based protection feature effectively detected overcurrent conditions, ensuring device safety by cutting off the electrical current in critical situations. With IoT integration via Telegram, this system enables efficient and real-time remote monitoring without the need for direct conventional measuring instruments. The implementation of this system is expected to improve efficiency and safety in electrical power management in both industrial and residential sectors.
