FIELD: electrical engineering.
SUBSTANCE: invention can be used in electric engineering for protection of ship power plants with parallel operating sources of energy (SE). Essence of the said method consists in the fact that in the method of protecting the network of an autonomous power plant with parallel operating electric power sources (SE), the faulty SE is disconnected from the network. At that, if in electric power state of network there is no instantaneous load release by value exceeding specified value at moment of SE transition into motor mode, SE is defined as faulty and disconnected from the network at the moment of transition to the motor mode, otherwise it is concluded that the SE is in working order and is disconnected from the mains.
EFFECT: shorter time for disabling inoperative SE from the network.
