Method and system for control power in remote DC power systems |
| 摘要 |
A method and system for a control power supply system is provided. The control power supply system includes a first conductor configured to carry a direct current (DC) electrical current from a source to a load, a second conductor configured to carry the DC electrical current from the load to the source, a electrical device electrically coupled in series with at least one of the first and second conductor. The electrical device is configured to fail in a shorted condition such that failure of the electrical device maintains a direct current (DC) ring bus including the first and second conductor. The control power supply system also includes a control power circuit electrically coupled in parallel with at least a portion of the electrical device such that a DC voltage across at least a portion of the electrical device provides a DC voltage supply to the control power circuit. |

1. A control power supply system comprising:
a first conductor configured to carry a direct current (DC) electrical current from a source to a load; a second conductor configured to carry the DC electrical current from the load to the source; an electrical device electrically coupled in series to at least one of said first and second conductor, said electrical device comprising a plurality of diodes coupled in series with at least one of said first conductor and said second conductor, wherein: each diode of said plurality of diodes coupled in a forward bias direction with respect to a flow of the DC electrical current in said first conductor and said second conductor; and said electrical device configured to only fail in a shorted condition such that failure of said electrical device maintains a DC ring bus comprising said first conductor and second conductor; and a control power circuit electrically coupled in parallel with a portion of said electrical device such that a DC voltage across said portion of said electrical device provides a DC voltage supply to said control power circuit. |
