Abstract

Electrical protection is essential to keep electrical systems safe. A suitable protection system can create a safe situation in the event of an overcurrent or voltage drop in the power grid. This can be caused by various factors such as usage, short circuits, or other disturbances. An electrical load control system regulates and monitors power consumption to prevent overcurrents and short circuits. The current reading process uses the current sensor and voltage sensor PZEM-004T, and when the set consumption exceeds the consumption, the relay holds the electric load. Also, the LCD is used to display the power consumption, and the keypad is used to enter the power limit. On the other hand, remote monitoring uses NodeMCU ESP826. Arduino Uno R3 is also a microcontroller that controls the central system. This study aims to create a prototype to monitor, limit, adjust, and control energy consumption to minimize energy consumption. This tool can monitor current and voltage and limit electrical energy consumption if necessary. This research is expected to alleviate the problem of house fires caused by overcurrents.

Abstract

This study aims to design and analyze a Load Frequency Control (LFC) system for a power plant with a reheat turbine, using PID-based controllers with various filter configurations to optimize frequency stability under load fluctuations. A series of PID, PD, and PDF controllers is implemented and tested through MATLAB simulations, focusing on key dynamic performance indicators such as rise time, peak time, settling time, and maximum overshoot. The findings reveal that PD and PDF controllers—particularly those that omit droop characteristics and incorporate filters—consistently outperform conventional PID controllers regarding faster response and improved transient stability. The integration of filters plays a crucial role in dampening oscillations and reducing overshoot, which is essential in maintaining system robustness during load disturbances. However, the study also identifies that the absence of droop control introduces limitations in achieving steady-state accuracy. Despite improvements in dynamic performance, the system continues to exhibit steady-state deviations, highlighting a trade-off between transient responsiveness and long-term stability. This underscores the need for hybrid or adaptive control strategies that combine fast response benefits with droop-based steady-state correction. The study contributes valuable insights toward developing more resilient and efficient frequency control mechanisms in modern power generation systems.

Abstract

This study presents a comprehensive methodology for measuring Sound Pressure Level (SPL) utilising MATLAB software. Through analysing four distinct categories of audio signals—Pink Noise, White Noise, Sinusoidal, and Real Audio—this research aims to investigate the fundamental acoustic properties associated with each signal type. The SPL measurement process employs specialised MATLAB functions tailored to each specific signal. The results are meticulously analysed to better understand the acoustic responses regarding energy and frequency spectrum. Furthermore, visual representations of the audio signals are provided to facilitate a clearer understanding of the structure and patterns inherent in each signal type. The outcomes of this study contribute valuable insights into SPL measurement within diverse audio contexts while also advancing the understanding of MATLAB’s role in exploring acoustic characteristics. The analysis is expected to offer a refined perspective on the application of MATLAB in acoustic research, thereby showcasing its broader potential within the field of audio engineering. Consequently, this research makes a significant scientific contribution and paves the way for future advancements in the domain.

Abstract

Semi-active dampers reduce the effects of shock vibrations because they can operate at specific vibration frequencies at a lower cost than more complex active dampers.  PSMEID is one of the alternative methods developed in the semi-active damping system. PSMEID has been developed by adapting it by adding a PSMEID active time prediction system when an impact occurs. This research attempts to compare two types of PSMEID with active time prediction, where the position of each model offered has a different PSMEID mass position when applied to the landing gear damper of an Unmanned Aerial Vehicle (UAV). This comparison aims to give the user a choice among these optimal models suitable for use in multiple conditions. When simulated using the same parameter values, the PSMEID placed on the unsprung mass can reduce acceleration amplitude by up to 6.6 percent when the landing gear is dropped at 0.15 meters from the ground. The model that places the PSMEID on the sprung mass can help reduce the velocity amplitude up to 8.8 percent when dropped at a height of 0.05 meters, and the spring constant value of the PSMEID (KPS) is 1600 N/m. All these simulations show that the PSMEID should be activated just before the landing gear hits the runway surface (TB < TL).

Abstract

The need for electrical energy is changing and increasing, requiring system flexibility always to be changed and developed. On the other hand, changes in the configuration of the electric power system due to the addition of components or sub-systems also change system parameters such as impedance or level of fault current (short circuit current). This paper presents a study of changes in the fault current caused by adding a new generating bus to an electric power system. This paper aims to determine the change in short-circuit current due to the addition of generators on new buses connected to existing buses to identify the most suitable location for adding these generators based on short-circuit current levels. Three-phase short circuit faults are simulated and analyzed on the IEEE 14 bus standard system using ETAP software with a base MVA 615 MVA. The addition of generators was carried out at five locations with varying generating capacities. The research results show that the short circuit current will change significantly when adding a generator bus to bus 13, with an average percentage change of 5,656%. The smallest change occurs when adding a generator to bus 2, with an average percentage change of 2,417%. The research results conclude that connecting a generator to a new bus linked to an existing generator bus (PV bus) is more effective than connecting it to a new bus associated with a load bus (PQ bus).
