Abstract
Information is conveyed from a generating site to a consuming location in an electric power system by varying the frequency of the power from the nominal standard generating frequency. The signaled variation in frequency is detected at a power controlling or consuming location and a frequency indicating signal is generated. Frequency deviations of predetermined magnitude for predetermined time duration signal a selected range of power system load while different deviations for different times signal automatic remote control of certain predetermined loads or other functions.
