Design of Wind Turbine Output Voltage Control Systems in Multi-Input Buck Converter Using Fuzzy Logic Control for Battery Charging

摘要

The wind energy is a renewable energy that continues to be developed in Indonesia. The one area that has wind energy potential is East Java. The wind profiles in East Java have a wind speed range of 0-10 m/s. The wind speeds that vary each time cause the voltage of the wind turbine generator to change as well. This can be proven through simulation with Matlab simulink software. The multi-input buck converter and its control is a method of controlling the voltage of a wind turbine generator. The stable output voltage is expected to charge the battery. The wind turbine used is type AF 1-24-0125 (406 PMG) with a generator in the form of PMSG. The control method use fuzzy logic control with three input and two output. The fuzzy controller use Sugeno method for defuzzification. The transient-response characteristics for a multi-input buck converter has a delay time of 0.012 s, rise time of 0.1859 s, peak time of 0.1870 s, and settling time of 0.1870 s. The maximum error generated is 0.1618 Volts or 1.037%.
