FIELD: electrical engineering.
SUBSTANCE: use in the field of electrical engineering to protect ship power plants from overload in emergency situations. Method of protecting the network of an autonomous power plant by disabling an unprofitable electric power source from it is that determination of the inoperative state of the source is carried out by the presence of the fact of the end of the process of including all working electric power sources for parallel operation at the moment of the transition of the source of electrical energy to the motor operating mode.
EFFECT: reduction of the time of disconnection of the unprofitable electric power source from the network and, accordingly, exclusion of the possibility of network overload, disconnection of efficient sources of electric power, de-shipment and loss of its controllability.
