Unformatted text preview: connected to bus D is equal to 5 MW at a pf of 0.9 lagging. Compute the perunit model for the above system. 2) Compute the load voltage (Bus D). 3) Compute the active and reactive power supplied by Bus A. 4) Compute the active and reactive losses. 3 66 (Keyhani Lecture) Given: Bus 1 is slack bus: V=1 Scheduled power at Bus 2 is 1.2 p.u. Scheduled load at Bus 3 is 1.5 p.u. Compute: 1) Y BUS model 2) Bus voltages using GaussSeidel Method 3) Power mismatch at Bus 2 and 3 4) Power supplied by the swing bus 5) Power loss of transmission lines 67 (Grainger and Stevenson, Jr. Chapter 9, Prob 9.1) 4 68 (Keyhani Lecture) Use NewtonRaphson Method to compute the bus voltages and power mismatches at Bus 1, 2, and 3 in Problem 66....
