Rancang Bangun Sistem Pembangkit Listrik Tenaga Surya untuk Upaya Kemandirian Energi Sensor Keamanan Kendaraan Bermotor

Abstract

Electricity is an important source of energy, widely used and integrated in society’s daily functions. With its ever-increasing usage, an alternative method of producing electricity that doesn’t rely on environmentally negative affecting non renewable energy sources is required. One of those alternative renewable sources is solar power. Motor vehicles are one of the most prolific methods of transportation used by almost everyone. This proliferation often marks them as prime targets of theft. As reported by the residents of the perumahan Villa Palem Kencara, where there have been 2 cases of grand theft auto in the past month. To assist the residents, the installation of a security device utilizing a RFID sensor has been proposed. However, the lack of additional power sources on location should the local PLN grid suffers a power outage, creates a potential weakness for the security device. This paper aims to design a solar power generating system to ensure the security device’s energy self-sufficiency and help mitigate a potential vulnerability of the device. This research analyses the performance of the solar power system, the average total energy consumed by the security device and the power system’s battery self-sufficiency. The design of the power system couples the solar power plant with the local PLN grid through the use of an automatic transfer switch (ATS), if one source was to experience an outage, the ATS system will switch between power sources. Thus, maintaining the security device’s energy self-sufficiency. From the testing process the solar power system is shown to be able to power and fulfill the energy self-sufficiency requirements of the security device. From testing the security device, the average energy consumption was found to be 3.1W or 24.8 Wh in stand-by mode and 11.2W or 89.6 Wh in work mode, with an operational time of 8 hours. The solar power plant was able to generate on average 32W or 256 Wh of energy for 8 hours. The battery used is able to power the security device independently for 8 hours without recharging until a depth of discharge of 50%.
