Load-shedding control for diesel-electric sets

摘要

A load-shedding control for diesel-electric motor-generator sets, which allows temporary overloads to be accommodated without engine lugging by reducing the line voltage if an attempt is made to draw more than a presettable maximum normal wattage. The line voltage reduction is accomplished by automatically increasing the impedance of the voltage regulator input circuit when a signal generally proportional to line voltage and load current exceeds a preset reference signal to which it is compared.
