“…Parameter motor induksi kecil industri sama dengan motor induksi peralatan pendingin, dan mendekati motor induksi irigasi. Jadi motor induksi kira-kira dapat dibagi menjadi tiga kategori: A = motor industri tegangan menengah (10 kV/6 kV), B = motor industri tegangan rendah (380 V), C = motor AC perumahan komersial tegangan rendah (380 V) [5]. Sistem pendingin Transformator PLTU Labuan juga menggunakan metode OFAF [6].…”

In an era marked by technological advancement, the demand for electrical power continues to surge, particularly in the midst of globalization and digitalization where electricity has become indispensable in daily life. State-owned electricity provider PLN is tasked with efficiently meeting this demand. To achieve this, PLN has established power generation facilities known as power plants. Electricity transmission from these plants to substations is facilitated through long-distance transmission systems like the SUTET cables. Before reaching substations, voltage from power plants such as PLTU Indramayu is boosted using Main Transformers. Despite meticulous preparation by PLN, challenges persist due to aging infrastructure, necessitating proactive maintenance programs. A critical aspect of infrastructure maintenance is the cooling system for transformers, crucial for voltage regulation. PLN employs the Oil Forced Air Forced (OFAF) mode for cooling the main transformers at PLTU Indramayu, ensuring efficient operation based on oil and winding temperature indicators. This system offers cost-effective maintenance and operation, boasting a capacity of 16 EA motor fans and 6 EA motor pumps, each operating at 380V 3 phase.Abstrak --Di era kemajuan teknologi, permintaan akan listrik terus meningkat, terutama di tengah globalisasi dan digitalisasi di mana listrik telah menjadi hal yang tak terpisahkan dalam kehidupan sehari-hari. Penyedia listrik yang dimiliki negara, PLN, bertugas untuk memenuhi permintaan ini secara efisien. Untuk mencapai hal ini, PLN telah mendirikan fasilitas sumber listrik yang dikenal sebagai pembangkit listrik. Transmisi listrik dari pembangkit ini ke gardu induk difasilitasi melalui sistem transmisi jarak jauh seperti kabel SUTET. Sebelum mencapai gardu induk, tegangan dari pembangkit listrik seperti PLTU Indramayu ditingkatkan menggunakan Trafo Utama. Meskipun PLN telah melakukan persiapan yang cermat, tantangan masih ada karena infrastruktur yang sudah tua, sehingga mengharuskan program pemeliharaan yang proaktif. Aspek kritis dari pemeliharaan infrastruktur adalah sistem pendinginan untuk transformator, yang penting untuk regulasi tegangan. PLN menggunakan mode Oil Forced Air Forced (OFAF) untuk pendinginan transformator utama di PLTU Indramayu, memastikan operasi yang efisien berdasarkan indikator suhu minyak dan kumparan. Sistem ini menawarkan pemeliharaan dan operasi yang hemat biaya, dengan kapasitas 16 motor kipas dan 6 motor pompa, masing-masing beroperasi pada 380V 3 fase.

This paper introduces a neural network adjustment method for a single gain of an IP speed regulator, to improve the speed control of an induction motor. Thanks to its simplicity and strength the (IP) controller is widely used in the industry for speed control. Yet, in some cases, when the load or mechanical parameters change according to its working conditions, the IP efficiency decreases and the setup quality degrades. In this case, a neural IP-self-tuning seems to overcome these difficulties and ensure a good control performance. The results obtained through the implementation of the proposed control on a dSPACE system and an induction motor clearly demonstrate the effectiveness of this method.

“…However, a significant challenge arises in accurately representing each element of the grid at a specific frequency [22]- [24]. Numerous scholarly articles and monographs have been dedicated to the exploration of this subject [25], [26]. Furthermore, the investigation of the impedance characteristics of grid components is of significance in light of the escalating demand for power [27]- [29] and the consequent adoption of renewable energy sources [30]- [32] driven by environmental considerations and the global endeavor to mitigate greenhouse gas emissions [33]- [35].…”

This study examines different methodologies for representing an asynchronous motor at higher harmonics by utilizing its equivalent circuit. Several approaches were compared based on simulation modeling. An experimental investigation was conducted in a laboratory setting using asynchronous electric motors with power ratings of 1.5 kW and 5.5 kW. The purpose of this investigation was to examine the characteristics of impedance in the presence of high-harmonic conditions. The generation of higher harmonics was achieved through the utilization of a precisely regulated thyristor rectifier in conjunction with a thyristor power controller. The findings indicate that the load on the shaft solely impacts the resistance at the fundamental harmonic, while the resistance at higher harmonics remains unaffected by the operating mode of the asynchronous motor (AM).
