Abstract

Wind energy is an emerging and popular source of clean energy due to its non-polluting nature and low cost. The efficient use of wind energy requires accurate and precise wind parameter measurements, which is where wind resource assessment (WRA) comes into play. The IoT and cloud-based systems have been applied to remote monitoring systems and provide crucial solutions for data acquisition, storage, and analytics in wind energy technology. This study aims to build a remote WRA system integrated with the Internet of Things. This study utilizes an Arduino Uno microcontroller, RK100-01 wind speed sensor, BMP280 temperature and pressure sensor, and SIM800L GPRS module to collect and transfer real-time data to the ThingSpeak cloud. The experiment was conducted at Atma Jaya Catholic University of Indonesia - Campus 3 BSD with the remote WRA system installed inside Stevenson screens to protect it from environmental conditions. Wind speed data is measured at a height of 10 meters, while air pressure and temperature data are measured at a height of 1.5 meters. Data retrieval utilizes two methods, viz. direct measurement every 15 minutes, and cloud-based retrieval every 30-second intervals. The study demonstrates that a remote WRA system integrated with IoT can measure, display, and upload three crucial parameters for assessing wind energy potential, namely wind speed, air pressure, and air temperature. This remote WRA system also provides flexibility in real-time data collection since it is accessible anytime and anywhere, thereby reducing the need for site visits during deployment.

Abstract

The use of cellular phones is increasing in society, but due to the limited battery capacity of cell phones, it is necessary to charge the battery when travelling in the long distances. The Savonius type wind turbine has a potential as an energy source harvesting the wind energy flowing around the car. However, due to the available space on the car, careful design of Savonius vertical axis wind turbine for vehicle is necessary. The research is conducted numerically using MATLAB software. The wind speed, Reynolds number, and electric power output are numerically simulated to obtain the swept area design. Innovative PLA material in the design is also investigated by simulating the effect of mass inertia moment to the design. This design of Savonius vertical axis wind turbine for vehicle is expected to charge maximum four cell phone batteries with the total electrical output of 60 W. The optimum swept area design of Savonius vertical axis wind turbine for vehicle is 0.150 m2 using 3 fins, PLA filament material, with an overlap of 5.3 cm, and a diameter for each blade 22 cm according to the overlap ratio used of 0.242. This Savonius vertical axis wind turbine design is feasible as an energy source for vehicle owing to its compact design, innovative material used in the design, and providing the electric power demand in the vehicle.
