Sistem Kendali Automatic Transfer Switch dan Monitoring Pada Pembangkit Listrik Tenaga Surya Untuk Usaha Mikro Laundry
Abstract
An independent electricity generation system using renewable energy, namely sunlight, is a Solar Power Plant (PLTS). The design of PLTS in this micro laundry business aims to more efficiently reduce PLN electricity consumption. The addition of the ATS control system to the PLTS was created as an energy backup for the washing machine when the main power source goes out. This research is an experiment with a calculation and measurement approach. The tests carried out were to test the performance of PLTS with the ATS control system and Node-Red based monitoring and the amount of savings in September. The solar panels produce an average current of 9.12 A and a voltage of 13.79 V. Battery capacity usage for loads does not exceed 50% DOD. The average battery charging current is 8.20 A with an estimated full charge of 15 hours without loading. This month's savings are IDR 31,495 from August's electricity bill. The intensity of sunlight and the amount of laundry done are the main factors in the results of PLTS work. The strength of the WiFi signal influences the speed of reading and transferring data, namely the use of power, voltage and electric current of PLN and PLTS in the red node-based monitoring system. This PLTS can work optimally so that it is able to withstand loads according to the specified capacity
