REACTIVE POWER UNIFORM DISTRIBUTION APPARATUS Russian patent published in 2006 - IPC G05F1/20 H02J3/46 

FIELD: systems for uniform distribution of reactive power between connected in parallel voltage sources.

SUBSTANCE: apparatus is designed for uniform distribution of reactive power between connected for parallel operation voltage sources having voltage regulators of those voltage sources with the same number of inlet terminals of each voltage regulator. Apparatus includes several groups of windings of differentiating induction measuring transducers (one for each voltage source); number of said groups is equal to number of inlet terminals of each voltage regulator. Each winding of any group is coupled inductively with one of load-current conductors of said power sources that are connected to inlet terminals of voltage regulators of said sources. Load current conductors which are inductively coupled with windings of the same group are connected between similar-polarity terminals of said voltage sources and one of common buses connected with load. Apparatus includes in addition (one for each group of windings) parallel-operation transformers. Each transformer is connected with windings only of one group and it has the same turn number in all windings. Primary windings of said transformers are connected to windings related to first (driving) power source having voltage regulator whose inlet terminals are connected to outlet terminals of said source. Each secondary winding of any transformer is connected between inlet terminal of voltage regulator of other (driven) voltage source and back end terminal of winding inductively coupled with current conductor of said source. Lead end terminal of said winding is connected to such outlet terminal of voltage source that is connected with said current conductor. Voltage sources with different nominal currents are used with windings whose mutual inductance with load electric current conductors have voltages inversely proportional to nominal currents of voltage sources.

EFFECT: improved quality parameters of produced electric energy.
