FIELD: electrical engineering.
SUBSTANCE: use in the field of electrical engineering for the protection of ship and other autonomous electric power systems (SEES) with parallel operating GUs in case of failure of one or several of them. In the method of protecting the power plant, when several GUs work in parallel, which consists in disconnecting the unworkable GU from the network, additionally, when one or several GUs go into the motor mode, they measure the load of each GU remaining in the generator mode, compare it with the specified load value, and at the moment when the load of at least one of them exceeds the specified value, the GU, which has switched to the motor mode, is defined as unworkable and disconnected from the network.
EFFECT: improving the shutdown speed of inoperative GU from the network.
