A method for monitoring power supply systems

Transmission procedures of transmission facilities (PNU, PNC) of a power supply network (EVN) for the transmission of information on at least a part (Pn P1 ...) designed such that the transfer devices (PNU, PNC) at least (with one of the transmission facilities PNU, PNC hold) permanent contact and from the results of the permanent contacts of the operating state of the at least one portion (P1 ... Pn) of the power supply network (EVN) is derived. The operating status automatically determined is reported to a central monitoring station (CS), a suppression of the disturbed in power supply networks (EVN) may be initiated.
