    In the design of superconducting AC generators the inner and outer rotors aie supported on thin torque tubes. This type of rotor structure introduces a torsional natural frequency, whereby the inner and outer rotor of the generator move in opposition, the frequency of which is influenced by the rotor electromagnetic structure. In this paper an analysis of the torsional natural frequencies within t... View full abstract»

    A new equivalent generator model to replace a group of coherent generators is discussed. The model is simple and can easily be implemented in transient stability programs. Derivation of the parameters of the proposed equivalent generator does not follow the common approach of calculating a new set of parameters for a new or hypothetical generator. The model is derived in such a way that its dynami... View full abstract»

    A digital simulator of transformer windings, which allows the computation of the transient responses to any input waveforms, is presented. Transformer windings showing a very irregular response with numerous resonant peaks are considered. The structure of the proposed simulator includes a transversal digital filter that uses the winding impulse response. This response is obtained analytically by m... View full abstract»

  • Electrical performance of aluminium/copper bolted joints

    Publication Year: 1982, Page(s):177 - 184

    The 1350 aluminium/copper bolted joint is fundamentally less secure than the all-aluminium connection. Differential expansion shearing force at the interface is considered to be a significant degrading influence. As a consequence, substantial clamping pressures are needed in addition to having regard to surface preparation and bolting torques. Although inert greases are used at the interface to re...
