Repeat Exercise 17 with Rw = 10 22, and verify your answers with appropriate PSpice simulations if the operating frequency is 60 Hz. 19. Each impedance Zp in the balanced three-phase system of Fig. 12.34 is con- structed using the parallel combination of a 1 mF capacitance, a 100 mH inductance, and a 10 22 resistance. The sources have positive phase sequence and operate at 50 Hz. If Vab=208/0° V, and Rw = 0, calculate (a) all phase voltages; (b) all line voltages; (c) all three line currents; (d) the total power drawn by the load. 20. With the assumption that the three-phase system pictured in Fig. 12.34 is balanced with a line voltage of 100 V, calculate the line current and per-phase load impedance if Rw = 0 and the load draws (a) 1 kW at a PF of 0.85 lagging: (h) 300 W per phase at a PF of 0.92 leading
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.
