SOURCE OF REACTIVE POWER Russian patent published in 2011 - IPC H01F29/14 

FIELD: electricity.

SUBSTANCE: invention refers to the sphere of electrical engineering. Source of reactive power (RPS) comprises three-phase capacitor battery made of sections and connected to circuit, three-phase magnetisation-controlled reactor, controlled rectifier with lead for grounding, three-phase filter of high harmonics, system of automatic control, besides, reactor has six rods. Two each rods of reactor are covered with network winding of each phase of network, on each rod of reactor there is a control winding arranged as separated into two parts, control windings are connected to outlet of controlled rectifier. Reactor includes compensation windings, which cover reactor rods. Parts of control winding of each phase are connected into three two-arm half-bridges. Each of two arms of half-bridge consists of serially connected two parts of control winding on two rods of each phase, each half-bridge of phase consists of serially connected two arms and is connected to outlet of rectifier, at the same time middle points of serial connection of arms of half-bridges are connected to grounding lead.

EFFECT: increased reliability and provides for overvoltage protection.
