Beschreibung
Zusammenfassung:	The invention relates to a method for monitoring a power supply network comprising at least one device for measuring measured values of at least one measurable variable of the power supply network. The invention also relates to a system for carrying out said method. Frequency-dependent or short-term changes of the power supply network stability can be represented by determining different model images based on different chronologically sampled measured values and can be detected by comparing the model images. Said comparisons are made particularly by expert systems, and the results of the comparisons are made available to an operator as possible options for action in order to monitor the power supply network.
