Abstract

Transient stability is an important aspect in maintaining the continuity and reliability of the electrical power system when a sudden large disturbance occurs. However, there is a time operation's limitation of the protection system to eliminate disturbance before the system becomes unstable and loses its synchronization. Critical Clearing Time (CCT) is the toleration time to eliminate the fault to keep the system stable. To improve system stability, installing Supercapacitor Energy Storage (SCES) can be one of the methods for extending the CCT values. SCES absorb large amounts of electricity simultaneously when a fault occurs. This paper proposed a determination of SCES' controller effect in extending the CCT. SCES becomes a dummy load and extends the CCT value depending on the controller's ability to respond to a fault. Controller modeling is applied to SCES, which is installed at the bus generator with determined capacity. The modified Fouad and Anderson 9-bus 3-machine system with a single machine to an infinite bus is used to validate the proposed method. Moreover, the critical trajectory method, which is known as a faster calculation and better accuracy than the time domain simulation method, is used to obtain the CCT value. The result shows that the faster controllers work against fault, the higher the CCT value improvement of system CCT. The highest improvement occurs when the controller works at 0.001s.

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

Budidaya ikan lele merupakan salah satu subsektor perikanan air tawar yang memiliki kontribusi signifikan terhadap ketahanan pangan dan ekonomi lokal di Jawa Timur. Meskipun demikian, hasil studi lapangan pada kelompok peternak “Patel Lele” di Dusun Mulyorejo, Banyuwangi, mengindikasikan adanya permasalahan mendasar dalam pengelolaan kualitas air, khususnya terkait kestabilan kadar oksigen terlarut yang selama ini masih dipantau secara manual. Permasalahan ini berimplikasi pada rendahnya efisiensi produksi serta tingginya biaya operasional listrik. Untuk menjawab tantangan tersebut, tim pengabdian masyarakat ini mengusulkan dan merealisasikan implementasi sistem aerator diffuser otomatis berbasis Internet of Things (IoT) yang dipadukan dengan teknologi hybrid photovoltaic. Metodologi pelaksanaan mencakup tahap perancangan perangkat, integrasi sistem monitoring berbasis sensor oksigen, uji coba kinerja, serta instalasi dan pendampingan mitra. Hasil pengujian menunjukkan bahwa sistem mampu menjaga kadar oksigen pada level optimal, beroperasi secara berkelanjutan melalui pemanfaatan energi surya, dan secara signifikan menurunkan ketergantungan pada suplai listrik konvensional. Selain memberikan peningkatan produktivitas budidaya, kegiatan ini juga menghasilkan transfer pengetahuan mengenai teknologi energi terbarukan dan sistem budidaya berkelanjutan. Dengan demikian, implementasi sistem ini berpotensi memperkuat kapasitas produksi perikanan lokal sekaligus mendukung pencapaian Sustainable Development Goals (SDGs) terkait energi bersih dan efisiensi sumber daya.

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.
