Two 30 22 parallel transmission lines supply a motor and a static load as shown in the figure. Answer the following questions. 20 MVA 11 kV j0.15 pu 25 MVA 12.5 kV/132 kV j0.1 pu G j30 Ohms j30 Ohms 25 MVA 132 kV/11 kV j0.1 8 MVA M 132/11 KV j0.1 pu ΔΥ Static Load 12 MVA, 11 kV, 0.8 lag ΔΥ (a) Choosing transmission line voltage 132 kV and the generator 20 MVA as base quantities determine pu impedance values and draw diagram of the power system shown in the figure. (b) Determine the pu and actual currents through the transmission line. (c) If the voltage at the load bus remains constant at 1.0 pu, determine the voltage regulation of the line.
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.
