Title:
ARRAY OF ELECTRICAL GENERATOR UNITS AND SHEDDING OF INTER-UNIT TRANSMISSION CABLES IN RESPONSE TO FAULT
Document Type and Number:
WIPO Patent Application WO/2017/114697
Kind Code:
A3
Abstract:
An array (1001) of generator units (1020) each producing a DC electrical output that are connected in parallel to provide the array DC electrical output. The array is connectable to a receiving station (1026) by output power transmission cables (1024), each transmission cable being connected to a respective one of the generator units being array output units. Each array output unit is connected to at least one other of the generator units in order to receive the DC output from the respective connected generator unit, and each generator unit that is not an array output unit is connected to one or more array output unit and/or to one or more other non-array output generator unit so that its DC output is transmittable to any one or each of the units to which it is connected and so that the DC output of each generator unit is transmittable to said at least two output transmission cables (1022). The array further includes fault detection means for detecting faults in the transmission cables (1022, 1024). In response to detection of a fault, the fault detection means causes switch devices (1007) at each end of the faulty cable (1022, 1024) to open to disconnect the respective generator units (1020) from the faulty cable.
