As shown in Figure 13.33, two identical, single-phase, two-wire, lossless lines are connected in parallel at both the sending and receiving ends. Each line has a 400-W characteristic impedance, 3 ? 108 m/s velocity of propagation, and 100-km line length. The source voltage at the sending end is a 100-kV step with source impedance ZG _ 100 W. The receiving end is shorted ZR _ 0_. Both lines are initially unenergized. (a) Determine the first forward traveling voltage waves that start at time t _ 0 and travel on each line toward the receiving end. (b) Determine the sending- and receiving-end voltage reflection coecients in per-unit. (c) Draw the Bewley lattice diagram for 0 < t < 2:0 ms. (d) Plot the voltage at the center of one line versus time t for 0 < t < 2:0 ms.
