Abstract
The present invention relates to a redundant power supply system for wind turbine control systems, said power supply system being adapted to supply power to one or more power consumers of a wind turbine control system, the redundant power supply system comprising a first power rail, a second power rail, and switching means being adapted to select the first or the second power rail so as to provide power to at least part of a power consumer from either the first power rail or the second power rail. The invention further relates to an associated method.

A redundant power supply system for wind turbine control systems, said power supply system being adapted to supply power to one or more power consumers of a wind turbine control system, the redundant power supply system comprising
- a first power rail (PR1),
- a second power rail (PR2), and
- switching means being adapted to select the first or the second power rail (PR1, PR2) so as to provide power to at least part of a power consumer from either the first power rail or the second power rail (PR1, PR2).
A system, comprising:
- a wind turbine;
- and
- a redundant power supply system operably connected to the wind turbine, the redundant power supply system being adapted to supply power to one or more power consumers of a wind turbine control system, the redundant power supply comprising:
- a first power rail (PR1),
- a second power rail (PR2), and
- switching means being adapted to select the first or the second power rail (PR1, PR2) so as to provide power to at least part of a power consumer from either the first power rail or the second power rail (PR1, PR2).
A method for providing power to one or more power consumers of a wind turbine control system in a redundant manner, the method comprising:
- providing a first power rail,
- providing a second power rail, and
- selecting the first or the second power rail so as to provide power to at least part of one or more power consumers of the control system from either the first power rail or the second power rail.
