Abstract
An electrical power generator is characterized by a plurality of system parameters. The generator includes a controller for protecting the generator. The controller obtains data from which a present operating point of the generator and a power generating capacity of the generator can be determined. The controller further monitors data indicative of at least one system parameter as a function of time to detect an abnormality in a value of the system parameter. The controller then categorizes a type of event that caused the abnormality with respect to the data indicative of the system parameter as a function of time, the present operating point, and the power generating capacity. Finally, the controller provides a response for addressing the type of event that caused the abnormality.
