1. Apparatus for use in a power generating system comprising a generating station having at least one generator and load wherein power is generated at a nominal standard frequency and wherein said standard frequency varies with applied generation and load, comprising:

  • A. signal generating means for producing binary encoded electrical signals representing information;

    B. means including at least one controller responsive to the application of said binary encoded electrical signals for pulse-code modulating the frequency of the power generating system to produce binary encoded information in the power system frequency corresponding to the binary encoded electrical signals;

    C. interconnecting means interconnecting said at least one generator with said at least one load; and

    D. receiving means connected to said interconnecting means for detecting said pulse-code modulation of the frequency of the power generating system and for decoding said binary encoded information to produce electrical signals representing said information.
