Abstract
SUPERVISORY equipment for the remote control of plant has proved to be thoroughly reliable and to facilitate efficient operation of electricity supply systems. In a paper read in London on March 14 by W. Kidd and E. M. S. McWhirter before the Institution of Electrical Engineers, the authors give the reasons for, and the steps taken to develop, the common-diagram control system, which enables an almost unlimited number of substations, etc., to be controlled completely from one diagram and control panel, and is sufficiently flexible to cater for the growth of an undertaking. It describes a wall-type system diagram which automatically indicates, which substations have changed conditions, and therefore the area involved in any disturbance. The system diagram is equally extensible to accommodate new feeders and substations with a minimum of operating disturbances. Particulars of the circuits and apparatus, and comparisons of floor area, pilot and cost economies are given in the paper, together with information relating to an installation dealing initially with seventy-eight substations, to which others are being added.
