1317330 Equalizing load on generators A P PEDRICK 17 Dec 1970 60101/70 Heading H2H An electricity supply installation, operating on the principle of using excess generating capacity to drive a flywheel and then using the flywheel to drive the generators at times of peak loading, is characterized by the form of the flywheel. To produce the flywheel, an annular pit 1 is excavated in the ground and lined, e.g. with cement. A concrete annulus 3 is cast in situ in the pit and secured to a steel plate 5. The assembly 3-5 is then mounted for rotation on a vertical axle 9. Drive to and from the flywheel may be effected by frictional engagement with rollers 12 which may be constituted by heavyduty vehicle wheels. The associated generators 9, to be driven by the flywheel at peak demand times, are distributed around the flywheel periphery. To drive the flywheel electric motors M, similarly distributed may be employed. Alternatively, (Fig. 5, not shown), the flywheel may be driven by turbines in the form of 'Pelton buckets' carried by the wheel.
