A short transmission line is a transmission line that has a length less than 80 kilometers, an operating voltage level of less than 20 kV, and zero capacitance effect.

Power Flow Analysis

Power flow analysis is a topic in power engineering. It is the flow of electric power in a system. The power flow analysis is preliminary used for the various components of Alternating Current (AC) power, such as the voltage, current, real power, reactiv…

Complex Form

A power system is defined as the connection or network of the various components that convert the non-electrical energy into the electric form and supply the electric form of energy from the source to the load. The power system is an important parameter …

A 4-cell reuse cellular system is being rolled out into an operation area and you are the engineer taking charge of this project. The subscriber density for the operation area is 600 people per km2. The average traffic load generated per subscriber is 0.2 Er. You are required to deploy 8 clusters of cells in the operation area and provide a Grade of Service of 0.5% to the subscribers using the blocked calls cleared model. You found out that the total number of trunk channels available to the system is 140. Assuming that fixed channel assignment is used, compute: a) The traffic load that can be offered to the operation area. b) The size of the operation area (in km2) that can be supported by the system. c) The proposed cell area and radius, based on the operation area determined in part (b). Having successfully implemented the first system above, you are now tasked to implement another system. The requirement is that, this second system must have a cluster size of 7 and provides a…
