Q3. In case of generator stator single phase earth fault, how to protect 100% range of the stator winding? Explain the principles of related protections in detail.

In this part of the assignment, you will need to calculate the cross-correlation of two random signals. In the Appendix: Part II, we include the function ccorr that gives you the crosscorrelation of two input vectors.

MATLAB provides other built-in function that may be useful for this part of the assignment

• max: gives you the maximum value of a vector. For more information type help max

find: gives you the index corresponding to a value of a vector. For more information type help find.

Finally, you will also need to use a linear filter in Exercise 3. You can use the function linfilt that you already used in MA2.

You can calculate the cross-correlation between two random signals in MATLAB by using the function ccorr given in the Appendix: Part II. As an example, consider two random signals x(t) and y(t), which are both modeled as white Gaussian random processes with mean 0 and variance 1. We plot the cross-correlation function Rxy(? ) of the random signals x(t), y(t) by applying the following MATLAB code:

t = -10:0.01:9.99;

x = randn(1, length(t));

y = randn(1, length(t));

[cc, tau] = ccorr(x,y,t);

plot(tau,cc);

In the same way you can plot the autocorrelation of signal x(t) [ac, tau] = ccorr(x,x,t); plot(tau, ac);

Now assume that y(t) is the output of a linear filter with impulse response h(t) = |sinc(t ? 2)|

where the input x(t) is a white Gaussian random signal with mean 0 and variance 1. Create an M-file to:

(a) Calculate y(t) using the function linfilt and plot x(t) and y(t) where t ranges from ?10 to 9.99, using 0.01 increments. NOTE: y(t) is the output signal of the filter, so if N is the length of the vector t, the length of y(t) is N + N ? 1 (convolution of two functions with length N). You will have to find the indices that correspond to t from ?10 to 9.99.

(b) Plot the cross-correlation function Rxy(? ).

(c) Plot the autocorrelations Rxx(? ) and Ryy(? ) of x(t) and y(t), respectively.
