METHOD FOR CHECKING MULTIPLE SPATIALLY DISTRIBUTED PROTECTIVE DEVICES OF AN ENERGY SUPPLY NETWORK, AND CORRESPONDING CHECKING SYSTEM

The invention relates to a method for checking multiple spatially distributed protective devices (SE1, SE2) of an energy supply network (3). In the event of a fault (5) in the energy supply network (3), each of the protective devices (SE1, SE2) is designed to insulate the fault (5) in the energy supply network (3). The method has the following steps: a: generating an initial check sequence, b: outputting the check sequence to the protective devices (SE1, SE2), c: detecting outputs of the protective devices (SE1, SE2), said protective devices (SE1, SE2) outputting the outputs on the basis of the check sequence, and d: analyzing the outputs and generating inputs for the protective devices (SE1, SE2) depending on the outputs. If the inputs are not components of the check sequence, the inputs are incorporated into the check sequence, and the method is continued from step b, otherwise the method is continued from step e: evaluating all the outputs of the protective devices (SE1, SE2). Each check sequence comprises inputs in the form of process variables of the energy supply network (3) for at least one of the protective devices (SE1, SE2).
