Question

value of x = 0.4, value of y = 0.5

c) The electricity network data provided in Figure Q3 is to be used for a load flow study. Bus 1 V=1 p.u. Slack Bus jo.05 p.u. j(x) p.u. Last digit of your student number 0, 3, 6 1,4,7 Bus 2 j0.025 p.u. (0.8 + j0.6) p.u. Bus 3 P= Y p.u. |VI=1.02 p.u. Figure. Q3 The line reactance X between Bus 1 and Bus 3 and the real power output Y of the generator connected at Bus 3 is given in the table below. Value of X Value of Y 0.2 0.6 0.4 0.5 2,58,9 0.1 0.8 Note that the values for X and Y to be used in the calculation depend on the last digit of your student number. Bus 1 is to be used as the Slack bus and Bus 3 is a generator bus. (i) Derive the bus admittance matrix (ii) Determine the voltage at Bus 2 after the first iteration of a Gauss Seidel load flow solution. (iii) Determine the estimated reactive power injection at Bus 3 and voltage at Bus 3 after the first iteration of Gauss-Seidel load flow.
