I need to describe mathematically the low-pass filtering effect of a doubly-fed induction generator. This is the description of the effect that I found:
The stator winding of an induction generator has an inherent inductance, which is a measure of its ability to resist changes in current flow. When the shaft speed of the generator oscillates, the frequency of the electrical output also varies, which causes changes in the current flowing through the stator winding.
However, due to the inductance of the winding, the current flowing through it lags behind the changes in frequency. This means that when the frequency of the electrical output changes rapidly, the current flowing through the winding cannot keep up with the changes. Instead, it lags behind, which causes the output voltage and current to be smoothed out.
This effect is known as low-pass filtering because it tends to filter out high-frequency variations in the electrical output. High-frequency components of the oscillation cannot pass through the inductance of the winding, so they are effectively blocked or attenuated. As a result, the electrical output of the generator becomes smoother and more stable, even when the shaft speed oscillates.
Could someone suggest some papers to read or approach how to describe mathematically the low-pass filtering effect of induction generator?
Thank you!
The low-pass filtering effect of an induction generator can be mathematically described using the transfer function of the stator winding inductance. The transfer function relates the output voltage to the input frequency and can be used to analyze the frequency response of the generator.
One paper that discusses the mathematical modeling of induction generators is "Mathematical Modeling and Dynamic Simulation of Doubly Fed Induction Generators" by J. M. Guerrero et al. (IEEE Transactions on Energy Conversion, 2005). This paper presents a detailed mathematical model of a doubly fed induction generator and includes the transfer function of the stator winding inductance.
Another paper that discusses the low-pass filtering effect of induction generators is "Low-Pass Filtering Effect of Stator Winding Inductance in Doubly Fed Induction Generators" by H. Li et al. (IEEE Transactions on Energy Conversion, 2012). This paper presents a simplified mathematical model of a doubly fed induction generator and analyzes the low-pass filtering effect using frequency response analysis.
Overall, the low-pass filtering effect of an induction generator can be analyzed using mathematical models that incorporate the transfer function of the stator winding inductance. These models can provide insight into the frequency response of the generator and help optimize its performance.
Hi Natha, thank you for the explanation and references. Your help is very much appreciated! Would it be possible for you to share the links to the papers you referred to in your explanation? I'm having trouble finding them in the IEEE library. Thank you!
Can anybody recommend some other papers or books to read about the low-pass filtering effect of induction generators? Thank you!
