Voltage regulation

Short line approximation. Here the line impedance Z = R + jL.

Voltage phasor diagrams for a short transmission line serving lagging, in-phase, and leading loads.

Comparison of 24-hour voltage swings on a feeder with no PV, 20% PV and 20% PV with volt-VAR control.

In electrical engineering, particularly power engineering, voltage regulation is a measure of change in the voltage magnitude between the sending and receiving end of a component, such as a transmission or distribution line. Voltage regulation describes the ability of a system to provide near constant voltage over a wide range of load conditions. The term may refer to a passive property that results in more or less voltage drop under various load conditions, or to the active intervention with devices for the specific purpose of adjusting voltage.
