A load of 1500 KW is connected at the receiving end of a 3 phase transmission line 70 km long. The parameters of the transmission line are given by r = 0.06 Ω/km and x = 0.9 Ω/km. The voltage at the receiving end of the transmission line is rated at 21 kV. If the machine is working at 0.75 power factor lagging. Determine a) The series reactance of the transmission line b) Sending end line voltage c) Percentage Voltage regulation d) Percentage Efficiency
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.
