Title:
STATIC REACTIVE POWER COMPENSATION EQUIPMENT
Document Type and Number:
Japanese Patent JP2514758
Kind Code:
B2
Abstract:
PURPOSE: To compensate fluctuated voltage by providing a two-phase/three-phase conversion transformer on the secondary single phase side of a three-phase/two- phase conversion transformer and providing a three-phase static reactive power compensation device (SVC) on the three-phase side.
CONSTITUTION: When three-phase AC power is supplied to this device, a three- phase/two-phase conversion transformer 2 is connected to the receiving terminal of the three-phase AC power, T seat and M seat single phase circuits on the secondary side are connected to the two-phase winding on the side to be the primary side of a two-phase/three-phase conversion transformer 6 of a reverse Scott connection, and a three-phase SVC 7 is connected to the three-phase side composed of a Scott connection to be the secondary side. The SVC generally consists of a thyrister of a reversed parallel connection, a reactor and a filter connected in parallel between the three phases, and inductance required for its structure way be replaced with the reactor and the inductance of the transformer may be used. Also, a fundamental wave operation (reactive power compensation) equivalent to the three-phase SVC provided on the receiving three-phase side can be conducted.
