Capital Study Analysis On Vertical Wind Turbine Type Savonius Type Rotor U Type Matlab Matlab Method Fast Fourier Transform (FFT)
Introduction
Savonius wind turbines are a type of vertical axis wind turbine designed to operate well at low wind speeds. In the process, moving wind flow will move the rotor or turbine propeller, which in turn produces an electric current. However, the amount of electric current produced is not only determined by wind speed, but also by the characteristics of the vibrations of the rotor type used. This study aims to explore the symptoms of vibrations that occur in the T-type U Savonius wind turbine rotor, using the Fast Fourier Transform (FFT) method.
Background of Savonius Wind Turbines
Savonius wind turbines are a type of vertical axis wind turbine that has gained popularity in recent years due to its ability to operate well at low wind speeds. The turbine consists of a rotor with a half-cylinder shape, which allows for more efficient wind flow and can capture more wind energy than other vertical rotors. However, the challenge arises when the rotor experiences absence or missalignment, which can be caused by a number of factors, including improper installation, wear, or even environmental effects such as sudden changes in wind direction.
The Importance of Rotor Design in Savonius Wind Turbines
The design of the rotor is a critical factor in determining the performance of Savonius wind turbines. The type of Rotor U, which has a half-cylinder shape, allows for more efficient wind flow and can capture more wind energy than other vertical rotors. However, the challenge arises when the rotor experiences absence or missalignment, which can be caused by a number of factors, including improper installation, wear, or even environmental effects such as sudden changes in wind direction.
The Use of Fast Fourier Transform (FFT) Method in Vibration Analysis
The FFT method is an effective analysis tool to identify the frequency and amplitude of vibration in the dynamic system. In this study, testing was carried out with five different independent variables, namely at a wind speed of 4 m/s, 4.5 m/s, 5 m/s, 5.5 m/s, and 6 m/s. The data obtained is then analyzed using a domain frequency graph, where the results of the analysis indicate the presence of misalignment symptoms, or the lack of shaft, on the rotor. This symptom is characterized by an increase in measurable vibration is greater than the normal state at the frequency of 2xrpm (rotation per minute).
Additional Analysis and Explanation
In the analysis of Savonius wind turbines, it is essential to understand how rotor design affects its performance. The type of Rotor U, which has a half-cylinder shape, allows for more efficient wind flow and can capture more wind energy than other vertical rotors. However, the challenge arises when the rotor experiences absence or missalignment. This inauguration can be caused by a number of factors, including improper installation, wear, or even environmental effects such as sudden changes in wind direction.
