Write down the general expression for the input impedance of a transmission line of length 1 and characteristic impedance Zo terminated by a load impedance Z1 . A complex load admittance Y = (a - j b)/ Zo terminates a length of line quarter wavelength long. Show that an impedance of (jb Z, ) will have to be connected in series with this line to create a purely real input impedance. What length L of short circuited line of characteristic impedance Zo and propagation constant ß would this correspond to? A quarter wave section of transmission line, is now inserted between this line (which includes the added series impedance) and a voltage source of internal impedance Zo. Show that the new line should have a characteristic impedance of Zo va in order to produce a matched load.
Short Transmission Line
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, reactive power, and voltage angles under given load conditions and is often known as a load flow study or load flow analysis.
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 in power engineering and the electrical engineering profession. The powers in the power system are primarily categorized into two types- active power and reactive power.
