Chapter 1 Wind Turbine Components - Iowa State University

Wind Turbine Components I Introduction Wind Turbines can be classified in two categories based on rotor structure. Vertical axis wind turbines have a main shaft that stands perpendicular to the direction of the wind stream. Horizontal axis wind turbines have a main shaft that lies along the direction of the wind stream.

Power System Simulation for Engineers (PSS/E version 30)

modeling delta-Y grounded, these will be zero. RG2, Xg2 are for impedance to ground on secondary side and since you are assuming secondary is solidly grounded, these are zero. R01 and X01 are the zero sequence impedance parameters for the transformer and should be entered in pu on the system MVA base.

Allan variance - Iowa State University

Allan variance 1 Allan variance The Allan variance (AVAR), also known as two-sample variance, is a measure of frequency stability in clocks, oscillators and amplifiers. It is named after David W. Allan. It is expressed mathematically as The Allan deviation (ADEV) is the square root of Allan variance.It is also known as sigma-tau, and is expressed ...

Discrete Fourier Transform (DFT)

Discrete Fourier Transform (DFT) Recall the DTFT: X(ω) = X∞ n=−∞ x(n)e−jωn. DTFT is not suitable for DSP applications because •In DSP, we are able to compute the spectrum only at specific discrete values of ω, •Any signal in any DSP application can be measured only in a finite number of points. A finite signal measured at N ...
