| 摘要 |
The invention relates to a method for monitoring the operation of a power generating installation that comprises at least one generator (1) that is driven by a rotating machine (2) in order to supply power to an electrical system (7), in which values of an operating parameter of the generator (1) and/or of the rotating machine (2) are captured and stored, it is ascertained whether the value of the operating parameter at prescribed checking times (t1 - t5) lies outside an admissible range, wherein a possible fault is inferred if the value of the operating parameter lies outside the admissible range at two directly successive checking times (t3, t4), an additional check is performed to determine whether the value of the operating parameter is approaching the admissible range in a prescribed checking interval (Δtp) that lies between the two directly successive checking times (t3, t4) and particularly extends as far as the later of the two checking times (t4), and it is inferred that there is a fault if the value of the operating parameter is not approaching the admissible range. The invention further relates to a device (8) for carrying out the method. |
