Chapter 28 Steady-State Transmission Lines and Power Flows

Transmission-Line Differential Equations

Consider a circuit representing a line section. The voltage and current are measured from the receiving end, with defined series impedance and shunt …

Lossless Lines

Consider a lossless line with a purely imaginary propagation constant, resistive characteristic impedance, and established ABCD parameters. Its equivalent …

Maximum Power Flow and Line Loadability

The maximum power flow for lossy lines is derived using ABCD parameters in phasor form. The matrix relationship between the sending-end and receiving-end …

The Power Flow Problem and Solution

The power flow problem calculates the voltage magnitude, phase angle, and real and reactive power flows in a balanced three-phase steady-state power …

Control of Power Flow

Controlling power flow requires managing components like generators' prime mover and excitation control, shunt capacitor banks, reactors, static var …

Fast Decoupled and DC Powerflow

Power system operations often face generator or transmission-line outages. Real-time contingency information helps anticipate problems and develop …

Electrochemical Etching and Characterization of Sharp Field Emission Points for Electron Impact Ionization

A new variation of the drop-off method for fabricating field emission points by electrochemically etching tungsten rods in a NaOH solution is described. …

A Video Surveillance System to Monitor Breeding Colonies of Common Terns (Sterna Hirundo)

Many waterbird populations have faced declines over the last century, including the common tern (Sterna hirundo), a waterbird species with a widespread …

Determining and Controlling External Power Output During Regular Handrim Wheelchair Propulsion

The use of a manual wheelchair is critical to 1% of the world's population. Human powered wheeled mobility research has considerably matured, which …
