Abstract: A mechanical assembly such as a torque transfer strut for a rotating superconducting machine. The torque transfer strut includes a composite tube having a first end received in a clamping fitting, which may include an end housing or lug, a clamping wedge screwed onto a threaded end housing, and an annular clamping member applying a radial clamping force to the first end of the composite tube at ambient temperature. When cooled, shrinkage of the end housing in the axial direction causes the annular clamping member to maintain or increase radial clamping force, causing the clamping wedge to apply increasing radial force to an inner member deflecting outwardly a plurality of axial fingers. The first end of the composite tube remains clamped between the inner member and an outer member, together defining an annular channel receiving the first end of the composite tube.

The method includes operating the DBS and controlling operation of the electrical machine based on a prevailing temperature of the braking circuit, stopping the electrical machine and controlling the electrical machine to be restarted at its rated output power once the prevailing temperature of the braking resistor reaches or falls below a lower temperature threshold. The electrical machine may be restarted at a lower output power and after restarting, its output power can be increased based on a power starting profile as the braking resistor cools.

Abstract: A system and method of operating a pumped storage power plant using a double fed induction machine with a frequency converter in a rotor circuit is disclosed. A current target value for the rotor current frequency is determined based on a target power to be transmitted between an electrical grid and the double fed induction machine depending on measured actual operating variables. A current inadmissible synchronous deadband is determined depending on variables characterizing a current state of the pumped storage power plant. The synchronous deadband is determined by a permissible minimum required rotor current frequency or speed difference of the rotor speed from the synchronous speed for the stationary operation. The converter is controlled to generate voltages and currents with the current target value of the rotor current frequency if the current target value of the rotor current frequency or speed does not fall in the current inadmissible synchronous deadband.
