METHOD FOR ADJUSTING POWER OF REACTOR WITH MAGNETIZATION Russian patent published in 2006 - IPC H01F29/14 

FIELD: electric engineering, in particular, engineering of devices for adjusting reactive power, possible use for adjusting network current and power of bridging reactors adjusted by magnetization for stabilization of network voltage in their connection point.

SUBSTANCE: in accordance to method, winding of reactor adjustment is connected in a triangle, and it combines functions of magnetization and compensation winding, transformer with converter is divided on three phases, positioned inside main tank of reactor, and connected by high voltage windings to reactor adjustment winding phases, and by low-voltage ones - to inputs of one-phased two-semi-period thyristor rectifiers, outputs of rectified current of which are connected to magnetization inputs of appropriate phases of reactor adjustment winding, while adjustment of magnetization current and, as a result, of current in network winding of reactor is performed independently in each phase by appropriate one-phased rectifier, in which thyristor adjustment angle is changed depending on discrepancy between setting voltage and voltage in reactor connection point, while with deviation of voltage from given setting by voltage angle of thyristor adjustment and time of their enabled state are altered so that resulting magnetization current and current of network winding of reactor provide stabilization of voltage in connection point on the level of given setting in accordance to astatic or static adjustment rule.

EFFECT: provision of phase-wise adjustment, simplification of circuit due to decreased number of elements and connections, increased reliability and stability of adjustment, expanded range of angles for adjusting thyristors, increased speed of reaching the mode of reactive power consumption.
