Abstract

The system can maintain its synchronization under a transient condition. The transient stability system can be evaluated using the critical trajectory method by calculating the Critical Clearing Time (CCT). The advantage of using a critical trajectory method is that the CCT can be found directly and more accurate than the time domain simulation method. This paper proposed the addition of Supercapacitor Energy Storage (SCES) and damping to enhance the transient stability on multi machine system. SCES is an electrical energy storage device that quickly stores and supplies large amounts of electricity, while damper winding damp the oscillations during unstable steady state conditions. Within the addition of SCES and damping in the system, the stability will last longer than before. The stability system is seen by the extended CCT. Furthermore, multi-machine to infinite bus used to validate the proposed method. The test system also includes the Automatic Voltage Regulator (AVR) and the governor

Abstract

The revitalization of control systems is an essential part of ensuring the reliability, safety, and operational efficiency of industrial facilities. One of the strategic projects undertaken is the revitalization of the Distributed Control System (DCS) at SHAFTHI, which aims to update hardware and software to meet current operational requirements. In its implementation, the adoption of the Engineer's Professional Code of Ethics serves as the primary foundation to ensure that every stage of work is carried out professionally, with integrity, and prioritizing safety, health, security, and the environment (HSE). This engineering practice emphasizes the application of ethical principles such as competence, responsibility to the public, objectivity, and compliance with technical regulations. By prioritizing the code of ethics, the revitalization of the DCS not only results in a more reliable and modern system but also provides assurance that the technical decisions made are aligned with ethical values and the interests of stakeholders. This implementation is expected to serve as an example of the application of engineering professionalism in addressing the challenges of technological modernization while maintaining public trust in the engineering profession.

Abstract

Preprocessing is a widely used process in deep learning applications, and it has been applied in both 2D and 3D computer vision applications. In this research, we propose a preprocessing technique involving weighting to enhance classification performance, incorporated with a 3D CNN architecture. Unlike regular voxel preprocessing, which uses a zero-one (binary) approach, adding weighting incorporates stronger structural information into the voxels. This method is tested with 3D data represented in the form of voxels, followed by weighting preprocessing before entering the core 3D CNN architecture. We evaluate our approach using both public datasets, such as the KITTI dataset, and self-collected 3D human orientation data with four classes. Subsequently, we tested it with five 3D CNN architectures, including VGG16, ResNet50, ResNet50v2, DenseNet121, and VoxNet. Based on experiments conducted with this data, preprocessing with the 3D VGG16 architecture, among the five architectures tested, demonstrates an improvement in accuracy and a reduction in errors in 3D human orientation classification compared to using no preprocessing or other preprocessing methods on the 3D voxel data. The results show that the accuracy and loss in 3D object classification exhibit superior performance compared to specific preprocessing methods, such as binary processing within each voxel.
