1. A 3-phase overhead transmission line has a total series impedance per phase of 200 480° ohms and a total shunt admittance of 0-0013490° siemen per phase. The line delivers a load of 80 MW at 0-8 p.f. lagging and 220 kV between the lines. Determine the sending end line voltage and current by rigorous |263-574 kV ; 187-5 A| method.
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.
