<p>A method for disconnecting a generator from a power system when the generator and the thereto connected power system are non-synchronized. The method includes the steps of: determining that there is a loss of synchronization between the generator and the power system, which loss of synchronization provides an amplitude variation of an electrical parameter associated with the generator. The method further includes determining when a minimum amplitude of the electrical parameter will occur, wherein when the occurrence of the minimum amplitude has been predicted, providing a command signal for disconnecting the generator from the power system, wherein the command signal is provided prior to the minimum amplitude of the electrical parameter is attained, and disconnecting the generator from the power system approximately when the determined minimum amplitude of the electrical parameter occurs. It is also presented a protection system for a generator in a power system.</p> |
