ABSTRACT:
An improved control system for static volt ampere reactance compensator provides for a transformation of the three phases into a two-variable system which thus isolates any common mode in the associated delta. Improved control is provided by utilizing the flux change as an advance indication of a disturbance. Lastly, the two-variable system, as it is inverse transformed into a three variable system, has its phasors rotated to prevent oscillation.
