Abstract
Power dispatching on an interconnected electric power system has been simplified and greatly improved by the adoption of a remote metering and automatic load control scheme recently developed. Remote metering at the power dispatching center provides continuous indication of the load on a distant 110-kv interconnection. The equipment also provides automatic control of the load on a hydroelectric generating plant located 160 miles from the metering point. The scheme, operating over company owned telephone lines, is based upon maintaining a constant beat frequency in the receiving apparatus, the transmission frequency being varied. Maintenance cost of the equipment is found to be negligible.
