    摘要： A cooling system includes a first section of high temperature superconducting (HTS) cable configured to receive a first flow of coolant and to permit the first flow of coolant to flow therethrough. The system may further include a second section of high temperature superconducting (HTS) cable configured to receive a second flow of coolant and to permit the second flow of coolant to flow therethrough. The system may further include a cable joint configured to couple the first section of HTS cable and the second section of HTS cable. The cable joint may be in fluid communication with at least one refrigeration module and may include at least one conduit configured to permit a third flow of coolant between said cable joint and said at least one refrigeration module through a coolant line separate from said first and second sections of HTS cable. Other embodiments and implementations are also within the scope of the present disclosure.

    摘要： A two-sided joint for splicing two laminated wires together, while preserving the mechanical integrity of the wire is disclosed. The two-sided joint can splice two laminated HTS wires having tapered ends and includes a bottom strap and a top strap. Under one aspect, a laminated, spliced superconductor wire includes a superconductor joint, which includes first and second superconductor wires, each wire including a laminate layer, a substrate layer overlaying the laminate layer, a buffer layer overlaying the substrate layer, a superconductor layer overlaying the buffer layer, a gap layer overlaying the superconductor layer, and a laminate layer overlaying the gap layer, a first HTS strap in electrical connection with the second laminate layer of the first laminate wire and the second laminate layer of the second laminate wire, and a backing strap proximate to the first laminate layer.

    摘要： A system for connecting a wind turbine generator to a utility power network includes a first power converter that converts an AC signal from the wind turbine generator to a DC signal and supplies a controlled amount of reactive current to the wind turbine generator. The system also includes a second power converter, connected in series with the first converter, which converts the DC signal from the first power converter to a line-side AC signal and supplies a controlled amount of current to the utility power network. A power dissipation element is coupled to the first and second power converters for dissipating power from the first power converter.

    摘要： In one aspect, in general, the invention features a control system configured for use with a three-phase PWM converter. The control system receives an input signal from a three-phase power supply and provides an output signal at a DC link. A voltage-separating module generates on the basis of the input signal a positive sequence voltage component and a negative sequence voltage component in a rotating reference frame. A reference current computation module uses at least the positive sequence voltage component and the negative sequence voltage component to compute a first reference current and a second reference current. A current regulating module uses at least the first reference current and the second reference current to generate a command signal. The command signal is provided to a driving circuit of the three-phase PWM converter for generating a regulated DC bus voltage at the DC link.

    摘要： Power compensation is provided from a power compensation device (30) to a utility power network (20) carrying a nominal voltage. The power compensation device has a steady-state power delivery characteristic. The power compensation is provided by detecting a change of a predetermined magnitude in the nominal voltage on the utility power network and controlling the power compensation device to deliver, for a first period of time and in response to the detected change in the nominal voltage, reactive power to the utility power network. The power compensation device is controlled to deliver, for a second period of time following the first period of time, reactive power to the utility power network at a level that is a factor N (N>1) greater than the steady-state power delivery characteristic of the power compensation device.

    摘要： A rotor assembly includes a superconducting winding assembly positioned within a cryogenic region of the rotor assembly. In operation, the superconducting winding assembly generates a magnetic flux linking a stator assembly. The rotor assembly also includes a torque transfer assembly that includes first and second tubes that are positioned in a radial space external to the superconducting winding assembly and that extend along a longitudinal axis of the rotor assembly.
