Dictionary of Electrical Engineering

Commonly used terms in the Electrical industry.

synchronous reference frame
a two dimensional space that rotates at an angular velocity corresponding to the fundamental frequency of the physical stator variables (voltage, current, flux) of a system.
In electric machines/power system analysis, an orthogonal coordinate axis is established in this space upon which fictitious windings are placed. A linear transformation is derived in which the physical variables of the system (voltage, current, flux) are referred to variables of the fictitious windings. See also arbitrary reference frame, rotor reference frame
See stationary reference frame
