Abstract
A var compensator circuit is provided. The var compensator circuit includes a gas tube switch and a reactive impedance. The gas tube switch is configured to be coupled to a transmission line. The transmission line is configured to deliver real power and reactive power to a load at an alternating current (AC) line voltage. The reactive impedance is configured to be coupled to the transmission line at the AC line voltage through the gas tube switch. The reactive impedance is configured to modify the reactive power configured to be delivered to the load.
Claims20
A voltage-ampere reactive (var) compensator circuit, comprising:
- a gas tube switch configured to be coupled to a transmission line, the transmission line configured to deliver real power and reactive power to a load at an alternating current (AC) line voltage;
- and
- a reactive impedance configured to be coupled to the transmission line at the AC line voltage through said gas tube switch, said reactive impedance configured to modify the reactive power configured to be delivered to the load.
A voltage-ampere reactive (var) compensator circuit, comprising:
- a gas tube switching network configured to be coupled between a first transmission line and a reactive impedance, the first transmission line configured to deliver real power and reactive power to a load at an alternating current (AC) line voltage, the reactive impedance configured to modify the reactive power configured to be delivered to the load, said gas tube switching network comprising at least one gas tube switch;
- and
- a controller coupled to said gas tube switching network, said controller configured to selectively commutate said at least one gas tube switch to couple the reactive impedance to the first transmission line and apply the AC line voltage to the reactive impedance.
A flexible alternating current (AC) transmission system (FACTS), comprising:
- a transmission line coupled between a power source and a load, said transmission line configured to deliver real power and reactive power to the load at an AC line voltage;
- a gas tube switching network coupled to said transmission line, said gas tube switching network comprising a plurality of gas tube switches;
- a controller coupled to said gas tube switching network, said controller configured to regulate said plurality of gas tube switches based on a measured AC line voltage and a measured AC line current;
- and
- a reactive impedance configured to be coupled to said transmission line through said gas tube switching network at the AC line voltage, said reactive impedance configured to generate additional reactive power.
