Abstract

Penelitian in bertujuan untuk merancang dan mengimplementasikan sistem Automatic Transfer Switch (ATS) yang mampu melakukan perpindahan sumber daya secara otomatis antara PLN dan sistem Pembangkit Listrik Tenaga Surya (PLTS) berbasis inverter, dengan waktu switching yang cukup cepat agar tidak menyebabkan perangkat melakukan restart. Metode penelitian yang digunakan adalah pendekatan rekayasa eksperimental, dimulai dari proses perancangan sistem ATS, implementasi perangkat keras, hingga pengujian pada tiga kondisi beban: tanpa beban, beban lampu pijar, serta kombinasi beban lampu dan komputer. Hasil pengujian menunjukkan bahwa waktu transfer rata-rata dari PLN ke PLTS adalah 229,333 milidetik dan dari PLTS ke PLN sebesar 271,333 milidetik, dengan nilai maksimum masing-masing 235 milidetik dan 297 milidetik. Waktu switching ini masih dalam batas toleransi untuk menjaga kontinuitas daya pada komputer tanpa menyebabkan gangguan operasional. Namun demikian, ditemukan adanya penurunan faktor daya (cos φ) akibat penggunaan inverter dengan gelombang modifikasi serta adanya switching berulang yang disebabkan oleh kegagalan sensor tegangan dalam membaca kapasitas baterai secara akurat. Penelitian ini menunjukkan bahwa performa sistem ATS sangat dipengaruhi oleh pemilihan jenis inverter dan keandalan sensor, sehingga diperlukan pengembangan lebih lanjut untuk peningkatan kestabilan dan akurasi sistem.   This research aims to design and implement an Automatic Transfer Switch (ATS) system capable of automatically switching power sources between PLN (State Electricity Company) and an inverter-based Solar Power Plant (PLTS) system, with a switching time fast enough to avoid restarting the device. The research method used is an experimental engineering approach, starting from the ATS system design process, hardware implementation, to testing under three load conditions: no load, incandescent lamp load, and a combination of lamp and computer loads. The test results show that the average transfer time from PLN to PLTS is 229.333 milliseconds and from PLTS to PLN is 271.333 milliseconds, with maximum values of 235 milliseconds and 297 milliseconds, respectively. This switching time is still within the tolerance limit to maintain power continuity on the computer without causing operational disruption. However, a decrease in the power factor (cos φ) was found due to the use of a modified wave inverter and repeated switching caused by the failure of the voltage sensor to read the battery capacity accurately. This study shows that the performance of the ATS system is greatly influenced by the selection of the inverter type and the reliability of the sensor, so further development is needed to improve the stability and accuracy of the system.
