The single line diagram of a power system is shown below. Load represented as impedance, (13.2) kV voltage It draws 60 MVA power from the system when it is below and (0.9) back power factor. Generators and transformers The related electrical parameters are given below. According to this; a) Calculate all impedances in this given circuit in pu and draw the equivalent impedance diagram of the circuit. (Select the base values as 100 MVA and 13.8 kV.) b) Since the voltage values of the generators are given as E1=1.1∟0° pu and E2=1.25∟10° pu, Calculate the value of the voltage (V1).
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.
