A long transmission line has the following parameters: A = 0.9413e.: = D, B = Z = 17.0e.: Y 2 = 2.7x10 + j9.07x10 At full load, the load current is 10 kA at 735 kV and 0.95 power factor lagging. Using the load voltage as reference: a) Calculate the voltage regulation of the line. [5] b) The line needs to be shunt-compensated by 30%. Calculate the new A parameter. [5] c) Find the voltage regulation after compensation. [5]
