  • Load peak shaver power regulating system
    Patent number: 4001666
    Abstract: A power regulating system controlling a flywheel-type load peak shaver is described wherein average power to a cyclic load is continuously subtracted from instantaneous load power to provide a command signal proportional to the required load peak shaver power flow. To this command signal is compared a feedback signal proportional to the power being supplied by the load peak shaver. The difference between the command and feedback signals controls the firing angle of a cycloconverter supplying power to the slip rings of the wound-rotor load peak shaver.
