Demand load control
Patent
·
OSTI ID:5595535
System, method and apparatus are described for carrying out the shedding of electrical loads on a predetermined priority basis. A sensor network detects a demand load at a power input and develops a signal representative thereof. This signal is introduced to a series of controllers along with a signal from an allowable load control circuit which represents a predetermined maximum allowable load value. The controllers respond when the demand load is higher than the allowable load, a priority delay network in each having a time-out interval corresponding with the relative priority basis assigned each load. Simultaneously, with the shedding of a load at the termination of the priority delay, a fictitious load feedback signal is summed with the demand load signal of the sensor. A reset control responds in conjunction with a predetermined review interval timing function to reevaluate the priorities of shed loads in the event of a drop in demand load.
