A single phase 50 Hz generator supplies an inductive load of 5,000 kW at a power factor of 0.707 lagging by means of an over head transmission line 20 km long. The line resistance and inductance are 0.0195 ohm and 0.63 mH per km. The voltage at the receiving is required to be kept constant at 10 kV Q1. the sending end voltage and voltage regulation of line Q2. the value of the capacitor to be placed in parallel with the load such that the regulation is requced to 50 % of that obtained in Q1 Q3. compare the transmission efficiency in parts of Q1 & Q2.
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.
