Title:
ＨＶＤＣグリッド内の障害保護のための方法、ＨＶＤＣグリッドのＨＶＤＣノード、及びＨＶＤＣグリッドシステム
Document Type and Number:
Japanese Patent JP7098059
Kind Code:
B2
Abstract:
The present invention concerns a node of a HVDC grid composed of HVDC nodes and of a plurality of links interconnecting the HVDC nodes, each HVDC node being interconnected to at least one HVDC node of the HVDC grid by a link composed of conductive cables for high voltage direct current transportation and one optical fiber, at least one HVDC node being interconnected to at least two HVDC nodes, each HVDC node comprising, for each link connecting the HVDC node to the at least one other HVDC node, a link module comprising a fault sensing device, a breaker, and an optical transceiver for communicating through the optical fiber of the link. The HVDC node interconnected to at least two HVDC nodes:- checks if a fault is detected on one link by a first link module,- transfers, if a fault is detected by the first link module, a first breaker disabling request through each optical transceiver of second link modules of the HVDC node that are different from the first link module,- disables the breaker of the first link module if a second breaker disabling request has been received by the first link module and does not trigger the breaking of the link by the breaker of the first link module.
