FIELD: electricity.
SUBSTANCE: method of automatic unloading of parallel generator units (HA) is that continuously monitor the technical condition of each HA by measuring a parameter indicative of its operating condition and comparing the measured parameter with a critical value, and the coincidence of the compared value signal is formed by summation of measured active loads both HA, while the total active HA load exceeds the allowable load value of HA, before the emergency shutdown of an inoperative HA, a signal is generated to turn off the pre-selected electricity consumers.
EFFECT: increasing the reliability of generator sets protection against overload.
