A three-phase generator rated 480 V and 400 kVA connected to a three-phase transformer rated 3.2 kV/480 V, 200 kVA, with reactance of 10% is used to serve a load over a line of 1 + j20 22. At the load site, the voltage is stepped down to 220 V from 3.2 kV using a three-phase transformer rated 150 kVA with reactance of 7%. The voltage at the load is to be maintained at 220 V. Perform the following: i) ii) iii) Give a one-line diagram. Compute a per unit equivalent circuit based at 200 kVA and 480 V. Compute the required generator voltage for unity power factor load. Is this design viable? Note for section iii: 1. unit factor load mean assume the current out of the generator = 1.0 pu L, 0 2. If the generator voltage is> 5% of the design voltage (1.0 p.u. or 480 V) then the design is not viable
