摘要：A demand limiting system is provided for a large electrical energy customerwith at least one modulating load. A master control unit continually compares the actualpower usage to the desired rate of power usage. When the desired power consumptionrate is exceeded by a first amount, the master provides a hold signal to an associatedslave control unit, which prevents further loading of the modulating load. When thedesired rate of power consumption is exceeded by a second amount, the master providesa reduce signal to the slave unit, which begins to reduce the load. While the hold signal iscalling for a reduced load, only a fraction of the time is utilized to reduce the load, andthe remainder of the time the modulating load is in the hold condition, allowing thesystem to stabilize and prevent hunting. The reduce signal also regulates load sheddingequipment, to disconnect non-critical loads. A safety and alarm circuit provides variousaudible indications and/or shut-down operations responsive to detection of various faultconditions.
