摘要： Embodiments of the present invention provide an approach for monitoring electrical disturbance (e.g., surges, outages, etc.) possibilities, and then automatically isolating electronic devices (also referred to herein as electronics) for the duration of the disturbance (or threat thereof). In a typical embodiment, a probability of an electrical disturbance occurring at a specified location will be determined. Then, a set of device protection profiles will be accessed. The set of device protection profiles comprises a set of thresholds and a corresponding set of device topologies associated with a set of electronic devices positioned. The set of thresholds in the set of device protection profiles will then be compared to the probability to identify a matching device topology from the set of device topologies. According to the matching device topology, at least one electronic device will be isolated from an electrical power source.

摘要： A quadrilateral distance module may be used to detect faults in an electrical power system. A resistive coverage of the quadrilateral distance module may be defined by an adaptive resistance blinder. The adaptive resistance blinder may be adapted to certain power system conditions, such as forward load flow and/or reverse load flow. A forward adaptive resistance blinder may be calculated in parallel with a reverse adaptive resistance blinder. The forward adaptive resistance blinder may use a polarizing quantity adapted for forward load flow conditions, and the reverse adaptive resistance blinder may use a polarizing quantity adapted for reverse load flow conditions. Fault detection may be performed by comparing both the forward and reverse adaptive resistance blinders to power system stimulus and detecting a fault when the stimulus satisfy either blinder.

摘要： The present invention relates to a method for testing multiple spatially distributed protective devices (SE1, SE2) of an energy supply network (3). Each of the protective devices (SE1, SE2) is configured so as to, in the event of a fault (5) occurring in the energy supply network (3), isolate the fault (5) in the energy supply network (3). The method comprises the following steps: a: production of an initial test sequence. b: outputting of the test sequence to the protective devices (SE1, SE2). c: detection of outputs of the protective devices (SE1, SE2) that the protective devices (SE1, SE2) output on the basis of the test sequence. d: analysis of the outputs and generation of inputs for the protective devices (SE1, SE2) depending on the outputs. If the inputs are not part of the test sequence, these inputs are incorporated into the test sequence and step b is proceeded with, while otherwise step e is proceeded with. e: evaluation of all outputs of the protective devices (SE1, SE2). Each test 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).
