Abstract

Pendistribusian barang merupakan salah satu hal penting yang dilakukan pada pabrik. Hoist crane merupakan alat transportasi barang yang umum digunakan untuk memindahkan barang seperti memuat dan menurunkan peti kemas, pekerjaan konstruksi bangunan, dan sebagainya. Namun, dalam penerapannya sering dijumpai ketinggian barang serta ketinggian tempat peletakan yang berbeda-beda, sehingga diperlukan tambahan operator untuk mengawasi penempatan hoist. Penambahan sensor ultrasonik merupakan solusi untuk mengurangi operator dan dapat membuat hoist berhenti tepat pada ketinggian yang diinginkan. Sensor ultrasonik digunakan untuk memberi data berupa jarak tempuh dengan cara menghubungkan keluaran sensor dengan Distributed Control System (DCS). DCS dihubungkan dengan Variable Speed Drive (VSD) sebagai pemberi tegangan ke motor. Pergerakan motor diatur menggunakan kontroler Proportional Integral Derivative (PID) yang parameternya didapatkan melalui metode Ziegler-Nichols, sehigga dapat menghasilkan pergerakan yang baik dan dapat mencapai kecepatan yang diinginkan. Dengan menggunakan algoritma PID, sistem mampu beradaptasi terhadap pembebanan dan perubahan nilai kecepatan yang diinginkan. Hasil pengujian menunjukkan bahwa sistem dapat digunakan untuk mengatur perubahan nilai kecepatan motor crane berdasarkan jarak. Kata kunci: kendali, crane, hoist, DCS, VSD

Abstract

ABSTRAK Penggunaan solar cell menunjukkan peralihan sumber energi dari energi fosil kesumber energi terbarukan semakin meningkat. Pembangkitan energi listrik berbasis cahaya matahari itu semakin berkembang, dari yang harus menggunakan baterai, hingga dapat digunakan paralel dengan jaringan elektris yang sudah ada. Sistem yang dapat memadukan sistem solar cell dan electrical grid disebut sistem on-grid. Komponen penting dalam sistem on grid tersebut adalah Grid Tie Inverter (GTI) yang dapat mensinkronkan tegangan keluaran solar cell dengan tegangan penyedia suplai listrik utama, yaitu Perusahaan Listrik Negara (PLN). Penyambungan GTI pada sistem solar cell ini akan memberikan dampak tertentu pada jaringan yang sudah ada, khususnya harmonisa sistem. Penelitian ini bertujuan untuk menganalisis dampak penggunaan GTI pada jaringan utama, baik ditinjau dari nilai harmonisa yang akan mengindikasikan distorsi yang terjadi, maupun dari besar faktor daya total. Pengukuran dilakukan dengan alat power quality meter dengan membandingan besaran pengukuran pada kondisi PLN tanpa solar cell dan kondisi PLN dengan solar cell. Besaran yang diambil pada pengukuran meliputi besaran parameter harmonisa seperti tegangan, arus, daya, Total Harmonic Distortion (THD) tegangan dan THD arus. Dari analisis yang dilakukan, nilai distorsi tegangan sistem PLN dengan solar cell lebih kecil dari distorsi tegangan PLN karena adanya filter pada GTI yang digunakan. ABSTRACT During the last decade, the use of solar cell is increasing due to the changing trend of energy resources, from fossil energy to the renewable energy. Power generating based on solar energy is getting developed and resulted in batteryless solar cell. The system that can combine the solar cell system and the electrical grid described as on grid system. One of the most substansial component in on grid system is the Grid Tie Inverter (GTI) that could synchronize the output voltage of solar cell with the output voltage of the main utility grid, which is Perusahaan Listrik Negara (PLN). The connection of GTI in solar cell system will have certain impacts to the main grid, especially the system’s harmonics. This paper aims to analyze the effect of the use of GTI to the main supply to its harmonics value, that indicates the distortion level, and also to its total power factor. Power Quality Meter been used as the measurement instrument to compare the measurement value in two conditions, PLN with and without solar cell. The research has been done by measuring harmonic parameter such as voltage, current, power, THD of voltage and THD of current. The result of the measurement shows that the distortion value of PLN with solar cell is lower than the distortion value of PLN without solar cell because of the addition of filter in the GTI

Abstract

In this time electrical energy is one of the most energy used. In industry electrical energy becomes a necessity that cannot be separated from the production process. Due to the need for electrical energy sources, of course, a protection system is needed to maintain the continuity and stability of electrical energy from existing disturbances such as short circuit disturbances. To overcome the short circuit, OCR is used. To assist the process of calculating loadflow and short-circuit current, ETAP12.6 is used. The results of the analysis of the ETAP 12.6 will be compared with the data obtained in the field with the aim of analyzing whether the use of the ETAP 12.6 software in assisting calculations and analysis in the selection of OCR settings. The difference in ocr settings in the ETAP 12.6 and field data has a difference of less than 2%. This difference is relatively small and can still be used to help the process in selecting the OCR settings.
