A power collection and transmission system can be used with a plurality of energy devices such as off-shore wind turbines (2), for example. The energy devices are grouped into two or more clusters. The system includes a dc collection network (N1, N2...N14)...

A fault detection method uses inertial measurements provided by an inertial measurement unit (IMU) (2) to detect faults in position measurement equipment (PME) (4). The method uses at least one inertial measurement ( ± ( t-N ) ...± ( t )) to derive at le...

The present invention relates to power distribution systems (e.g. a marine power distribution and propulsion system) that include first and second ac distribution busbars. The first ac distribution busbar (MVAC1) will typically be a medium voltage (MV) bus...

A power transmission and distribution system is described that it is suitable for subsea electrical loads. The system includes a primary dc transmission cable (8) that can be connected to an onshore AC/DC converter module (2) that connects the onshore end ...
