摘要： A method of maintaining a desired level of sub-transient reactance in a superconducting machine includes specifying a desired level of sub-transient reactance. A stator assembly is produced that includes at least one stator coil assembly having a first predefined length. A rotor assembly is produced that is configured to rotate within the stator assembly. An asynchronous field filtering shield, having a second predefined length that is less than the first predefined length, is positioned between the stator assembly and the rotor assembly. The desired level of sub-transient reactance is achieved by adjusting either the first predefined length or the second predefined length.

摘要： An electric coil includes bifilar pancake coils electrically connected to an adjacent pancake coil so that current flowing in adjacent turns of adjacent pancake coils flows in opposite directions at all radial region of the coil assembly. The superconducting fault current limiter is configured to provide a minimized inductance and low resistance in a normal state of operation. On the other hand, when a fault current exceeds a predetermined threshold, the resistance increases to a level sufficient for limiting the flow of fault current to a desired level until a circuit breaker connected within the electrical system opens the circuit.
