Problem #1: Take a two-bus system. Bus #1 is represented as an infinite bus with a constant voltage of 120 per unit. Bus #2 is represented as a load / PQ bus with a constant complex power draw (consuming power from system) of 125MW and-55MVAR. The power base for this system is 100MVA. The transmission line between buses #1 and #2 is represented by the pi-model. The series admittance between the buses is Y12-5-12.5pu. The shunt admittance at either end...
Antenna Input (load) A cell phone antenna has an input 500 admittance Yi(0.015j0.015) S that operates at a frequency of 1 GHz.
