The single-line diagram of a small power system is shown in Fig. 1. The corresponding reactance diagram, with reactances specified in per unit, is shown in Fig. 2. A generator with emf equal to 1.25/0 0° per unit is connected through a transformer to high-voltage node (3), while a motor with internal voltage equal to 0.85/-45° is similarly connected to node (4). Develop the nodal admittance matrix for each of the network branches and then write the nodal admittance equations of the system. T 1 سلت Fig. 1.

Question 3: A very simple model for the distribution of clectricity to a typical home is shown in the figure below. Some of components labeled a, b, c, d, c, f, g and h represent the electrical source to the home, some represent the wires that carry the electrical current from the source to the devices in the home requiring electrical power, some represent lamps, televisions, hair dryers and other devices that require power. Assume you are an engineer in charge of a project and one of your subordinate engineers reports that the interconnection in the figure does not pass the power check. The data for the interconnection are given in the table below. Is the subordinate correer? Explain your answer. If the subordinate is correct, find the error in the data. Explain your answer clearly. Based on your answer identify that which label(s) used for the electrical source, wires or other devices. a e h
