  • Patent number: 6897749
    Abstract: A superconducting magnetic energy storage (SMES) device including a first coil made of superconducting material, a cooling mechanism for cooling the first coil to superconducting temperatures, a second coil inductively coupled to the first coil for inputting emergy to, and/or outputting energy from, the first coil, and a switch for switching the first coil between a superconducting condition and a non-superconducting condition. The first coil is arranged as a closed loop electric circuit having no connecting device mechanically connected to it for inputting or outputting energy. The switch includes a third coil for the application or removal of a magnetic field for switching the first coil between its non-superconducting and superconducting conditions. A method inputs energy to and/or outputs energy from the first coil and a power supply system utilizes the device and method.

  • Publication number: 20040114403
    Abstract: A superconducting magnetic energy storage (SMES) device (1) comprising a first coil (2) made of superconducting material, cooling means (3) for cooling the first coil to superconducting temperatures, a second coil (4) inductively coupled to the first coil (2) for inputting energy to, and/or outputting energy from, the first coil (2), and switching means (5) for switching the first coil (2) between a superconducting condition and a non-superconducting condition. The first coil (2) is arranged as a closed loop electric circuit having no connecting means mechanically connected to it for inputting or outputting energy. The switching means (5) comprises a third coil for the application or removal of a magnetic field for switching the first coil (2) between its non-superconducting and superconducting conditions. The invention also relates to a method of inputting energy to and/or outputting energy from the first coil (2) and to a power supply system.

  • Publication number: 20040046530
    Abstract: A power plant comprises at least one turbine (5) driven by a variable medium flow and an electric generator (4) driven by the turbine and the induced voltage of which being an unambiguous function of the number of revolutions of the turbine. The plant has also first members (12) for detecting the electric power generated by the generator, second members (11) for detecting the voltage on the output of the generator, means (10) adapted to compare the values detected for said power and voltage with an ideal relation predetermined for the generator between these two quantities and an arrangement (10) adapted to regulate the induced voltage of the generator and thereby the number of revolutions of the turbine so that said ideal relation between power and voltage is obtained.
