Method for operating a power plant connected to an energy supply network

Method for operating a stationary power plant (2) connected to a power supply network (G), wherein upon occurrence of a dynamic network fault in the power supply network (G), in particular an electrical short circuit, at least one fault value (N1 - N29) is determined as a function of a status value (S1 - S9) of at least one operating parameter of the power plant (2), wherein the at least one fault value (N1 - N29) is assigned to at least one component (3, 4, 5) of the power plant (2), wherein a maintenance signal (M) for the at least one component (3, 4, 5) of the power plant (2) is output as a function of the at least one fault value (N1 - N29).
