Question

4. The three phase 400kV transmission line is 180km long. The end-of-line voltage is 410 kV and the load is 400 MVA with a power factor of 0.8 ind. The cable parameters are: r = 0.026 Ω / km, x = 0.33Ω / km, g = 0.023µS / km and b = 3.57µS / km. Calculate the cable transfer constants A, B, C, and D using the appropriate modeling method. Use a + i * b syntax for your answers.

Enter the displacement constant A.

Enter the transfer constant B.

Give the transfer constant C in the micro, i.e. 10 ^ -6.

digits (e.g. 12*10 ^ -6)

Enter the transfer constant D.

(Give the answer of accuracy of at least three to five significant digits.)
