Abstract

An induction regulator for controlling the voltage amplitude and / or phase angle of a polyphase electric transmission network connected between the primary side and the secondary side of the transmission network. The rotor is fixed in relation to the stator and the volume between stator and rotor includes a magnetic volume with a region including a controllable magnetic flux region of solid material that has a relative permeability that is controllable by changing its temperature.

Description

FIELD OF INVENTION

[0001] The present invention relates to an induction regulator for controlling the voltage amplitude and / or phase angle of a polyphase electric transmission network exhibiting a primary side with a primary voltage and a secondary side with a controllable secondary voltage, which induction regulator is connected between the primary side and the secondary side of the transmission network and comprising a stator with stator windings and stator poles and a rotor with rotor windings and rotor poles.

[0002] The invention also relates to a method of controlling the voltage and the phase angle of a polyphase transmission network for high voltage with an induction regulator.

[0003] The invention also relates to use of an induction regulator for power-flow control for a polyphase transmission network for high voltage.DESCRIPTION OF THE BACKGROUND ART

[0004] The active power flow in an ac network is controlled by the equationP=U1U2Xsinδwhere U1 and U2 are the voltages at the transmi...
