1) Three-phase, 50Hz, 200 km long power transmission line has an effective resistance of 0.128 2/km, an inductance of 960 µH/km and a capacity of 6.56 nF/km. It supplies an 80 MW load with a power coefficient of 0.8 back under 132 kV phase-to-phase voltage from the end of the line. Using the nominal equivalent circuit model, a) Find the voltage per line (V1), current per line (11) and power factor (cospl)?. b) Calculate the lost power and efficiency of the energy transmission line and interpret the result you found.
