As an electrical power system engineer, you must deal with the representations and performances of transmission line under normal operating conditions. Your manager Mr. Richard gives you a task i.e.; to analyzes the performances of a three-phase transmission line that has the following parameters: Transmission line length = 300 km Positive sequence series impedance of z =0.0267 + j0.62/ km Positive-sequence shunt admittance, y= j5.333×10S/ km . •. At full load condition, the line delivers PR= 2500 MW, 0.9 power factor lagging at 132 kV line voltage to the receiving end load. Mr. Richard has explained about transmission line representations, ABCD parameters, currents and voltages as a guide for you to do the analyses. Based on your practical knowledge, evaluate the performances of the transmission line. Then, categorize your finding whether of the transmission line is good, weak or poor.
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.
