摘要： A superconducting electrical machine 1 such as a ship's engine has a rotor 10 and a stator 30, the rotor having superconductive windings 15. The rotor 10 includes an additional normally-conducting winding 55 in parallel to the superconducting winding 15 but not normally connected. In the event of a fault in the superconducting winding 15, the additional winding 55 can take a sufficient current to run the engine to maintain mobility of the ship. Moreover, while this normally-conducting operation is under way, the heat generated warms the cooled engine ready for maintenance.

摘要： Generators 12a are for a distributed generation system. A control system 32a receives information about network faults 14a. In normal conditions, the control system 32a controls the field current in the field coils of the generator 12a, to maintain generator output voltage at the rated value. At the onset of fault conditions, the control system 32a changes the manner in which field current is controlled, in order to reduce the fault current put onto the network.

摘要： An electrical machine includes a stator including a plurality of electrical phases and a rotor having a plurality of magnets. Each electrical phase includes at least one coil and power electronics. There are means to detect an electrical short circuit in a faulted coil and means to supply an electrical current to the faulted coil when an electrical short circuit is detected in the faulted coil. The means to supply the electrical current to the faulted coil includes one or more un-faulted electrical phases of the electrical machine. The un-faulted electrical phases of the electrical machine are arranged to supply the electrical current to the electrical phase containing the faulted coil. The power electronics of the un-faulted electrical phases are arranged to supply the electrical current from the un-faulted electrical phase to the power electronics of the electrical phase having the faulted coil. This overcomes a problem of a fault in the DC or AC busbar of the electrical machine.
