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

Operations in the industry today use induction motors. There are several types of induction motors, one of which is a 3-phase induction motor. In the use of a 3-phase induction motor, there are several problems at the beginning, one of which is that there is a current surge in the starting received by the windings or rotor of a 3-phase induction motor which will cause damage to the motor windings. In previous research, research has been carried out to reduce electric starting spikes in 3 phase motors by lowering the frequency in a study entitled "Adjusting the Speed ??of a 3 Phase Induction Motor by Changing the Frequency Using the ALTIVAR 12P Inverter" it was found that the frequency of the regulated voltage was low and stable to minimize inrush current in 3-phase motor starting. Therefore, research was conducted on a system that can reduce these problems, namely the use of a star-delta system on a 3-phase motor to reduce electrical starting spikes in a 3-phase motor. In this study, the electric current value was 0.59 A, the star-circuit voltage value was 219.65 V, and the short-circuit current value was 1.01 A.
