摘要： A first protective device monitors a first section of a power supply network for a symmetrical short-circuit and a second protective device monitors a second section for a symmetrical short-circuit. The second protective device is a reserve protective device, which emits a shut-off command to a power switch after a time lag when a symmetrical short-circuit in the first section is recognized. An oscillation recognition unit emits an oscillating signal which blocks the shutoff command if an oscillation in the power supply network has been recognized. External symmetrical short-circuits can be disconnected independently of an occurring oscillation, when the second protective device has recognized a symmetrical short-circuit in the first section, before the oscillation recognition unit recognizes an oscillation in the power supply network, the shut-off command is emitted independently of the presence of an oscillating signal if the lag time has elapsed.

摘要： A fault signal indicates a single-pole or a double-pole fault in a three-phase electrical power grid which occurred during a present electric oscillation in the electrical power grid. The method assures that single-pole or double-pole faults occurring during oscillation can be detected with high reliability in that a symmetry signal is produced during the oscillation, which indicates whether the oscillation is symmetrical or unsymmetrical, and the phases of the electrical power grid are checked for an existing fault, wherein the symmetry signal is used for carrying out the check. The fault signal is produced if a fault was detected during the check. A protective device has an accordingly equipped control unit.

摘要： A method for producing an oscillation signal which indicates oscillation in an electrical power supply system, in which measured values that characterize current and voltage at a measurement point in the electrical power supply system are detected and are converted to digital current and voltage vector measured values. Impedance values are calculated in the complex numerical domain from the current vector measured values and the voltage vector measured values. A curve profile formed by the impedance values is considered and, if appropriate, the oscillation signal is produced using characteristic properties of the curve profile. In order to provide a method in which an oscillation can be identified as reliably as possible, a first oscillation supposition signal is produced when the separation of the impedance values from an oscillation center point remains substantially the same and a second oscillation supposition signal is produced when the rate at which the impedance values approach the curve profile remains substantially the same. The oscillation signal is produced when both the first and the second oscillation supposition signal are present. A protective device or measurement instrument has a corresponding oscillation identification device.
