Analysis of The Need For Solar Power Plants (PLTS) as a Backup Source of Electrical Energy at Base Transceiver Stations (BTS)

Abstract

The electricity supply for BTS power needs generally uses generator sets as the main energy source. On the other hand, the continuous use of generator sets also has a negative impact on the environment. Based on these issues, the use of environmentally friendly technology is one of the most suitable alternatives to be applied to the BTS system owned by telecommunications service providers. The use of solar energy as an alternative energy source will have a significant impact on saving fossil fuel consumption. From the data obtained, it is known that the power capacity for BTS operation per day is 10.6 kVA or 8.48 kW. If the BTS operates at a constant power for 24 hours, the total power required is 203.52 kWh. The next step is to determine the assumption of losses with a value of 15%. This is because all the components of the system used are new (not old or used components). Thus, the total energy requirement for the microgrid system will be 234,048 Wh or 234.048 kWh Translated with DeepL.com (free version). Based on the results of calculations and direct measurements, the BTS requires a power capacity of 10.6 kVA or 8.48 kW per day. The inverter capacity uses 10 kW more than the power required by the BTS to avoid overload when using the BTS load. The solar power plant at this BTS uses mono-crystal solar panels with a capacity of 455 Wp/panel and 183 solar panel modules are installed, bringing the total to 83,265 Wp. This solar power plant uses 11 batteries with a capacity of 48V 100 Ah. It uses 11 Solar Charger Controllers (SCC) with a capacity of 100-25A each Translated with DeepL.com (free version).
