Utilization of a Low-Speed Neodymium Wind Turbine Generator as an Alternative Power Source for Homes in the North Cirebon Coastal Area, Indonesia

Abstract

Wind energy, which is a renewable energy source, is inexhaustible, clean and free. Renewable energy sources, especially wind energy, offer many environmental and economic benefits in contrast to fossil energy sources. The potential and characteristics of wind energy in the northern coastal area of ​​Cirebon Regency are very good. This can be seen from the measurement results of an average wind speed of 3.3 m/s during the day between 10:00-15:00 WIB, which is suitable for a 100 W mini power plant. The distribution of wind speed is quite even with a range of 2.7-3.9 m/s. The neodymium type wind turbine generator design is capable of utilizing wind energy at low speeds of 2.7-3.6 m/s. The generator is specifically designed for low speeds so that it can operate and produce voltages above 11 Volts even in low wind conditions. This study uses experimental methods, system design and data analysis. The measurement results show that the generator is capable of working in the wind speed range of 2.7-3.6 m/s and produces a voltage above 11 V. There is a positive relationship between wind speed, generator rotation, and output voltage. This study is motivated by maximizing renewable energy sources and offering new solutions to reduce dependence on State Electricity Company in the region. It can be concluded that the neodymium generator is effective as an alternative electricity source because it is able to work at various wind speeds and produce adequate electrical power.
