Choose a = a0

and

Discrete Wavelet transform (DWT) of the signal X(k) is given by:

k

a,b

m

76 In the present analysis GABOR wavelet has taken as mother wavelet And

In the present analysis GABOR wavelet has taken as mother wavelet And

is given by the following equation.

-(t2/k)

?(t) = e (cos(t))

Where k =2,4,16,64------- With GABOR wavelet it is easy to find out the frequency Components of the signal because it is based on exponential Function like the fourier transform.

Representation of Transmission line model in MATLAB:

I n this model Transmission line is modeled as distributed Parameters line ,representing a 225-km-long,240-kv ideally Transmission line with +ve sequence impedance , ZL(1) = (8.05 +j 110.66) ?. Zreo sequence impedance,ZL(0) =(79.19 +j 302.77) ?. The Thevenin impedance of area A is Za =(5 +j 27.7) ?. The Thevenin impedance of area B is Zb=0.6 +j 9.3) ?. The source voltages are EA = 240KV, and Eb = 240

?

Where ? is the load angle in degrees.
