Abstract

Di Indonesia, PLN adalah penyedia utama listrik rumah tangga, individu, dan industri. Namun, karena pasokan listrik PLN tidak selalu stabil, pembangkit cadangan diperlukan. Karena mereka adalah sumber energi terbarukan dan ramah lingkungan, pembangkit listrik tenaga surya (PLTS) menggunakan energi matahari sebagai sumbernya. Namun, pasokan PLTS tergantung pada cuaca. Untuk mengatasi masalah ini, PLTS dapat dirancang sebagai Pembangkit Listrik Hibrid (PLTH), yang menggabungkan sumber PLN dan pengaturan beban. Studi ini mengembangkan sistem kontrol pintar otomatis dan manual yang menggunakan Automatic Transfer Switch (ATS). Sistem ini menggunakan ESP 32 dan memiliki mikroprosessor dengan modul WiFi 802.11b/g/n ESP 32 di Rentang Frekuensi 2.4 GHz. Studi rumah tangga menunjukkan bahwa kontrol pintar berfungsi dengan baik dalam simulasi dan pengujian. Meskipun ada waktu start-up inverter, delay rata-rata PLN-SHS adalah 1835 ms dan SHS-PLN adalah 2695 ms dalam mode otomatis dan 937,5 ms dalam mode manual dengan kontrol Thinger io. Dalam 12 pengujian, delay rata-rata kurang dari 2 s. Hasil menunjukkan bahwa jarak tidak memengaruhi delay, namun, kecepatan internet ESP 32 dan pengguna memengaruhi delay.

Abstract

This paper presents a dual-axis solar tracking system developed and evaluated using LDR sensors and stepper motors, controlled by an Arduino Uno microcontroller. The aim was to enhance photovoltaic energy efficiency by designing a system capable of automatically adjusting the position of solar panels to follow the sun's movement throughout the day. Comparative testing between static solar panels and those equipped with solar trackers demonstrated that the latter produced 35% more power on average. Additionally, the dual tracking system showed a 14% improvement in efficiency over previous averages noted in existing references. Analysis of azimuth and elevation angles confirmed that the solar tracker accurately adjusted the panels' position, significantly boosting solar energy capture. This finding is consistent with prior research, which also supports the efficacy of solar trackers in enhancing photovoltaic efficiency. Future research should expand testing to include various weather and environmental conditions and focus on developing more advanced control algorithms to enhance system responsiveness. Continuous advancements in solar tracking technology are vital for maximizing solar energy potential and facilitating a transition to a more sustainable society.

Abstract

ABSTRAKDesain yang sangat padat pada lokasi gulungan kabel streamer pada kapal seismik dapat menimbulkan titik-lemah karena lokasinya di tengah geladak dan area kerja operator di geladak belakang. Hal ini meningkatkan risiko kerusakan peralatan dan risiko terhadap keselamatan operator. Operator harus berjalan bolak-balik atau menugaskan operator lain untuk memantau gulungan kabel streamer yang berarti diperlukan waktu tambahan selama pengoperasian. Kedua opsi tersebut berkontribusi terhadap paparan ekstra risiko keselamatan dan penggunaan operator yang tidak efisien. Pada penelitian ini IP camera digunakan untuk memonitoring gulungan kabel streamer dan active infrared sensor digunakan untuk mendeteksi titik lemah. Desain sistem yang diimplementasikan ini mengurangi titik lemah sehingga mengurangi risiko keselamatan, meningkatkan efisiensi waktu, dan mencegah kerusakan peralatan.Kata kunci: optimisasi, kapal seismik, kabel, perangkat penggulungan ABSTRACTThe compact design of streamer cable reel locations on seismic vessels creates blind-spots due to their location in the center of the deck and the operator’s work areas aft of the deck. This increases the risk of equipment damage and the risk to operator safety. The operator must walk back and forth or assign another operator to monitor the streamer cable reels which means additional time is required during operation. Both options contribute to the extra safety risk exposure and inefficient use of operators. In this research, IP camera is utilized for monitoring streamer cable reel and active infrared sensor to detect blind spots. The implemented system design reduces blind spots that decreasing safety risks, improves time efficiency, and prevents equipment damage.Keywords: optimization, seismic vessel, streamer cable, spooling device

Abstract

A substation is one of the essential aspects of an electrically interconnected system, especially in a grid utility. Power generation, transmission, and distribution systems always need a continuous power supply to the customer. In high voltage and extra high voltage substation, operation schemes during abnormal and normal conditions may cause transient overvoltage in the system, one of which is temporary overvoltage. Temporary overvoltage analysis is needed to validate the rated system voltage within the limit of the substation equipment’s insulation level, including the rating of the lightning arrester. This research will select a lightning arrester with the standard approach IEC 60099-5 and software simulation on a computer. Conducted temporary overvoltage analysis using software simulation, which resulted in a value of 2.02 pu higher than the operating voltage. This slightly differs from the IEC 60099-5 standard, which recommends a value of 1.6 pu of operating voltage. Software simulation is beneficial as it models the system according to specific network parameters, leading to an optimal selection when compared to standards with different approaches to results based on varying network parameters. Temporary overvoltage analysis could help determine the correct rating of the lightning arrester and further mitigation, such as line compensation, switching technique, and load management, ultimately leading to reliability in substation equipment and interconnection system networks.

Abstract

This work introduces a predictive model for evaluating transmission losses in the Java-Bali electrical system using ensemble empirical mode decomposition (EEMD) and support vector regression (SVR) techniques. Transmission losses, a critical aspect of energy efficiency, are affected by several operational aspects, such as load flow, energy composition, peak load, and meteorological factors such as transmission line temperature. Transmission losses data were decomposed into many intrinsic mode functions (IMFs) by EEMD, effectively capturing both high-frequency (short-term) and low-frequency (long-term) trends. The SVR algorithm, utilizing a radial basis function (RBF) kernel, was subsequently employed to predict the deconstructed IMFs, facilitating accurate predictions of transmission losses. The proposed EEMD-SVR model achieved a mean absolute error (MAE) of 5.43%, with the highest error observed during the period of abrupt load shifts. These results confirm the model’s strength in identifying long-term transmission loss patterns, making it suitable for system planning and operational forecasting. While the model exhibited high prediction accuracy, especially in recognizing long-term trends, it faced limitations in accurately predicting abrupt changes in transmission losses. Therefore, future improvements should aim to enhance responsiveness to sudden changes in the system dynamics. The result suggests that the EEMD SVR model can proficiently assist power system operators in monitoring and mitigating transmission losses.
