Consider the single-line diagram of a power system shown in the figure with equipment rating as follows; Generator G1: 50 MVA, 13.2 kV, x = 0.15 pu Generator G2: 20 MVA, 13.8 kV, x = 0.15 pu Three-phase ∆-Y transformer T1: 80 MVA, 13.2∆/16YkV, X = 0.1 pu Three-phase Y-∆ transformer T2: 40 MVA, 165Y/13.8∆kV, X = 0.1 pu Load: 40 MVA, 0.8 PF lagging, operating at 150 kV Choose a base of 100 MVA for the system and 132 kV base in the transmission-line circuit. Let the load be modeled as a parallel combination of resistance and inductance. Neglect transformer phase shifts. Draw a per-phase equivalent circuit of the system showing all impedances in per-unit.

Problem 1: (2 points) a. Determine a T matrix that represents a rotation of 60° about the Z axis, followed by a translation of 4 unit of distance along the axis X, followed by a rotation of 30° about the fixed Y axis? b. A frame {A} is translated 4 unit of distance along the axis Z and then it is rotated 45° about the axis X. Consider a point with coordinates (0, 2, 1) with respect to the new frame {B}. Find the coordinates of that point with respect to the initial frame {A}.
