Appl. No.:

17/351960

Inventors:

- Union City CA, US
Hamed Khalilinia - Hayward CA, US
Niloofar Torabi - Menlo Park CA, US
Michael T. Garrison Stuber - Newman Lake WA, US
Sana Tayyab - Lahore, PK

International Classification:

H02J 3/18
H02J 13/00
G01R 31/08
H02H 1/00

Abstract:

Disclosed is a reactance-injecting module and its method of use to balance the currents among the phases of polyphase electric power transmission lines or to manage power flow among alternate paths, where the reactance-injecting module has high-speed, dedicated communication links to enable the immediate removal or reduction of injected reactance from all phases of a phase balancing cluster when a fault is detected on any one of the multiple phases. The reactance-injecting module may communicate information on a detected fault to the other reactance-injecting modules of the phase balancing cluster within 10 microseconds after the fault is detected to allow the phase balancing cluster to eliminate injected reactance from all phases within a time that is short compared to a cycle of the alternating current, such as 1 millisecond after the fault is detected. This provides extremely fast neutralization of injected reactance to minimize interference with fault localization analyses.
