Abstract :
In this paper it is the author´s endeavour to show not only that metering methods have played an important part in load-levelling, but that the load-levelling relay in connection with simple metering is a solution of the load-levelling problem. A considerable amount of attention and energy has been devoted to the ways and means of bringing about an improvement in the load factors of the various electricity supply undertakings; and as the load-levelling of the future will concern the distributing mains and consumers´ supply services, the author suggests that it will be a problem for the mains and meter engineers rather than for the power station engineers. In order not to delve too deeply into the very complex metering problems, the paper has been limited to the following six considerations:¿ (1) Load-levelling by metering, with various tariff methods. (2) Load-levelling control at the generating station and substations. (3) Some attractive off-peak loads. (4) Load-levelling relays on consumers´ premises. (5) General description of load-levelling relays. (6) Where load-levelling relays can be usefully employed.
