Question

A 60 Hz three-phasa trnsmission line is 300 mi long and servesa load of 400 MVA, with 0.8 lagging power factor at 345 kv . TheABCD constants of the line are: a) Determine the sending-end line-to-neutral voltage, thesending-end current and the sending-end active power. b)Percent voltage regulation. c)Transmission line efficiency at full load. d)Determine the line propagation constant and thecharacteristic impedance Zc e)Calculate the total series impedance and total shuntadmittance of the line g)Calculate the wavelength and velocity ofpropagation h)if the line is lossless (i.e. R=G=0); Calculate the surgeimpedance i)if the line is loaded with the surge impedance; Calculatethe SIL j)Re calculate the ABCD parameters for the lossless TL k)Re-calculate the line efficiency and voltage regulation forthe lossless line
