A three-phase radial network whose various equipmentcharacteristics are given below feeds, at the terminals of the MVbusbar (C) of its transformer, a water purification plant requiringa power of Pc equal to 12 MW with a return factor of 0.85 . By a MVcable link whose characteristics are given, this transformer alsofeeds, at busbar D, a flour mill with a rated power Pd equal to 2MW under an inductive power factor of 0.85. A P = 12 MW Cos 0 =0.85 D tot P = 2 MW Cos o = 0.85 Diagram of the radial networksection Element Characteristics Length ........ L = 100Km Nominalvoltage... Un = 110 KV Resistance (a term). R = 0.15 /km Re You areasked to determine the following parameters: 1. The equivalentdiagrams of the different elements of the network as well as theglobal equivalent diagram of the considered network; 2. The voltageat the HV busbar (A) at the power plant; 3. The apparent power S atthe line input (busbar A); 4. The power factor at the input of theline; 5. The losses in the line; 6. The voltage at busbar A whensplitting the HV line. 7. Comparing the single term HV line and thedouble term HV line, which configuration has advantages inoperation. You will fill in the comparison table below which mayhelp you to draw your conclusion. Parameters Case of a 1 term HVline Case of a 2-term HV line Longitudinal impedance between A andB 2 Cross-sectional Suscept.
