MULTI-TERMINAL DC ELECTRICAL NETWORK

摘要

A multi-terminal DC electrical network comprises a plurality of DC terminals, each DC terminal operatively connected to at least one other DC terminal via a respective DC power transmission medium; a plurality of converters, each converter being operatively connected to a respective one of the DC terminals, the plurality of converters including at least one designated converter; and a controller including a solver configured to use an algorithm to process a plurality of values to compute a no-load DC voltage for a first designated converter as a function of the plurality of values. The plurality of values include a first value defining an operating mode of each designated converter; a second value defining a default electrical characteristic of the multi-terminal DC electrical network or a computation parameter of the algorithm; and a third value defining an electrical measurement corresponding to a voltage or current in the multi-terminal DC electrical network.

1. A multi-terminal DC electrical network comprising:
a plurality of DC terminals, each DC terminal being operatively connected to at least one other DC terminal via a respective DC power transmission medium; a plurality of converters, each converter being operatively connected to a respective one of the DC terminals, the plurality of converters including at least one designated converter; and a controller including a solver configured to use an algorithm to process a plurality of values to thereby compute a no-load DC voltage for at least one first designated converter as a function of the plurality of values, the plurality of values including:
at least one first value defining an operating mode of the or each designated converter;at least one second value defining a default electrical characteristic of the multi-terminal DC electrical network or a computation parameter of the algorithm; andat least one third value defining an electrical measurement corresponding to a voltage or current in the multi-terminal DC electrical network, wherein the controller is configured to operate the or each first designated converter in accordance with the or the respective computed no-load DC voltage.
