  • Inaugural address. The electricity supply industry¿yesterday, today and tomorrow

    Publication Year: 1977
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (3019 KB)

    The Address is primarily concerned with the engineering aspects of the electricity supply industry at three points in time. The first part considers the immediate prewar years when electricity was supplied by widely varying undertakings. Aspects of generation, transmission, distribution and utilisation are considered in turn and comparisons are made with the present day where appropriate. The seco... View full abstract»

    Whereas for many years electronic techniques have had wide application in telecommunication transmission equipment, until relatively recently telecommunication switching equipment has been dominated by electromechanical techniques. However, this dominance is now rapidly disappearing as electronic techniques are increasingly employed in switching, often coupled with stored program (computer) contro... View full abstract»

  • Analysis of antenna structure with equal E- and H-plane patterns

    Publication Year: 1977, Page(s):25 - 30

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (536 KB)

    Analysis of an antenna structure which yields equal E- and H-plane patterns is presented in this paper. The structure consists of an excited slot with two symmetrically disposed and parasitically excited monopoles. The equalisation of the E- and H-plane patterns depends upon the coupling between the slot and the monopoles, which is a function of monopole height and separation from the slot. An eva...

  • Construction of variational principles and variational bounds in waveguide scattering

    Publication Year: 1977, Page(s):31 - 37
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (856 KB)

    Using projection operators, a variational-bound formulation is presented which, together with some previous work, can provide both upper and lower variational bounds on the phase shifts or equivalent network elements associated with obstacles located in waveguides. The scattering parameters for dielectric rectangular-parallelepiped obstacles in single and multimode waveguides serve as numerical ex... View full abstract»

    A large switched network has a complex pattern of interconnections which in practice is normally based on tandem connection of relatively simple units. It is shown that an alternative basis is possible, in which a large structure is built up as a Cartesian product of simple units. The resulting structure has some interesting topological properties, notably an overall homogeneity and a high connect... View full abstract»

  • IEE Power Division: Chairman's address. Design for living

    Publication Year: 1977, Page(s):49 - 53
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (863 KB)

    The loss of the home market has forced the British switchgear, turbine generator and transformer manufacturers to produce new designs to meet specifications differing appreciably from traditional British practice. A new range of switchgear will meet the high performance requirements of the home market and also provide an economic export product for most of the common internationally agreed voltage...

  • Design of low-voltage distribution networks: a mathematical programming method

    Publication Year: 1977, Page(s):54 - 58
    Cited by:  Papers (23)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (668 KB)

    A branch-and-bound/capacitated transhipment method for determining the optimal layout of a radial low-voltage-distribution network is presented. Branch-and-bound organisation, postoptimisation and list-processing techniques, used to solve problems of a realistically large size on medium-size computers, are discussed. Case studies and an example are also given. View full abstract»

  • Stator and network transients in multimachine power-system stability

    Publication Year: 1977, Page(s):59 - 60
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (190 KB)

    State equations are obtained for a multimachine power system including the stator and network transient terms which are commonly neglected. Results are shown for the transient stability of a 5-machine system and the accuracy of commonly used approximations is indicated. View full abstract»

  • High-performance low-pass filter utilising a mechanical energy store

    Publication Year: 1977, Page(s):61 - 66
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (760 KB)

    A novel low-pass power filter is proposed, in which a d.c. machine is used as a reactive element, replacing the conventional electrostatic capacitor. The equivalent capacitance of a suitably operated d.c. machine is, typically, several times larger than commercially obtainable electrostatic capacitors, and, therefore, a filter using a machine as one of its elements should have exceptional characte...

  • Analysis of eddy-current brakes with nonmagnetic rotors

    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (633 KB)

    The field distribution when a thin conducting sheet moves with constant velocity between two rectangular and infinitely permeable pole pieces of an electromagnet is obtained by conformal mapping, after reduction of the problem to two dimensions. This result is used in predicting the force/speed and flux/speed characteristics of eddy-current brakes with nonmagnetic rotors. Experimental results on s... View full abstract»

    In the present state of the British economy, industrial innovation, although not easy, is necessary, and the paper draws attention to some of the factors which make for success in this field. Various types of change are reviewed, and the process of innovation discussed generally; it is suggested that three particular stages are crucial, namely the creation of the original idea, the capture and sel...

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (440 KB)

    The optimisation of water resources systems has been the subject of several investigations throughout the world. Methods of optimisation such as linear, nonlinear and dynamic programming have been considered by many workers in the field. Dynamic programming has been one of the most widely used methods owing to its natural characteristics of being able to deal with discrete dynamic models and no li... View full abstract»

    The paper traces the development of standards of measurement from their earliest appearance in the weights and measures used in trade through scientific interest in systems of units to the complex of standards in use today. The work of the International Bureau of Weights & Measures and its associated committees in harmonising standards is discussed. The national electrical standards maintained... View full abstract»
