FIELD: electrical engineering.
SUBSTANCE: usage: in the field of electrical engineering to protect ship and other autonomous power plants (APP) with parallel operating generator units (GU) in the case of failure of one or more of them. Method allows to solve the problem of APP protection by means of disabling an inoperative GU at the time of its transition to the motor mode of operation. According to the method, parameters characterizing the power generated by each GU are measured, on the basis of the measurement results, the moment of time is determined, at which any of the GUs turns out to be inoperable and at the same time goes into the motorized mode of operation and disconnects this GU from the network.
EFFECT: technical result is reducing the time to disconnect an inefficient source of electrical energy from the network.
