Check your understanding Consider the following three-bus power system where transmission line impedances and power are shown in per unit on 100 MVA base: Po = 3.0 pu Bus 1 (slack) Bus 2 (PV) jo.2 pu V = 1.00 pu Bus 3 (load) (0:0 j0.4 pu j0.1 pu Sid = 2 + j0.3 pu V = 1.00 pu Ꮎ = Ꭴ° Sused = 3 + 30.5 pu Given the bus output data in per unit as follows: Bus # Angle (deg.) Ра Oc 1 1.0 0.5253 2 1.0 -11.9749 1.4574 3 0.9180 -24.7974 0.0 0.0 P. Q 0.0 0.0 0.0 3.0 2.0 0.3 3.0 0.5 a) Determine the power generation of the slack bus, Po, in per-unit b) Find the total reactive power losses of the system in per-unit c) Calculate the equivalent load impedance, Zxud, in per-unit ( magnitude and angle) at bus# 3
Write the power flow through the transmission lines in per unit (fill-in the table below): Transmission Line (Bus to Bus) P Q I to 2 1.0374 0.1088 2 to 1 -1.0374 0.1088 I to 3 0,4165 3 to 1 2 to 3 3 to 2 -0.5235
