摘要： A distributed busbar protection system using time-stamped data gathered from measurement devices in an electrical power system bus arrangement by respective intelligent electronic devices (IEDs). The IEDs may derive the timestamp information from a clock or other time source, which may be synchronized to a common time source and/or an absolute time. The time-stamped measurement data may be used by a protection device to monitor and/or protect the electrical power system. The protection device may include a real-time vector processor, which may time-align the time-stamped data, determine one or more bus differential protection zones, and implement a differential protection function within each of the protection zones. One or more protective control signals may be transmitted to the IEDs to trip the corresponding breakers and clear the bus fault.

摘要： Provided is a compensated inverse-time undervoltage load shedding system and method for use in an electrical power system. The compensated inverse-time undervoltage load shedding system includes a compensation element for determining a compensated value and an inverse-time undervoltage element operatively coupled to the compensation element and enabled based on the compensated value. When enabled, the inverse-time undervoltage element calculates a load shedding time delay value based on the compensated value, and determines a load shedding signal based on the load shedding time delay value. An associated load of the electrical power system is shed based on the load shedding signal. The compensation element may determine the compensated value using a voltage magnitude, a rate-of-change of power system voltage over time, a weighted rate-of-change of power system voltage over time, a current magnitude, a weighted current magnitude, and an impedance phasor value, to name a few.

摘要： A set of current measurements may be transmitted from a remote Intelligent Electronic Device (IED) to a local IED. The current measurements may comprise a timestamp and/or be associated with timestamp information to allow the local IED to time align the local current measurement with the remote current measurement. The local IED may detect a fault within the power system segment defined by the local and remote IEDs by comparing an operating current to a scaled restraint current. A fault may also be detected by comparing the operating current to a scaled nominal current. The operating and restraint currents may be derived from the local and remote current measurements. The restraint current scale may be derived from the characteristics of the local and/or remote IED. The current measurements may correspond to a negative-sequence component and/or a zero-sequence component of a three-phase current measurement set.

摘要： The system obtains the three phase voltages on the power line VA, VB and VC, either from a local primary or local alternative source. The selected local source voltages are then applied through switches, respectively, which are normally closed but are open in the event that the associated pole of each voltage phase is open. The voltages from the closed switches are applied to a calculating circuit which produces a composite of the three voltages in accordance with a preselected formula. The composite voltage output is then normalized and applied to a conventional frequency determination (estimating) circuit. This output is an accurate system frequency for use by the protective relay.

摘要： The system uses graph theory to define busline arrangements as a series of vertices and edges, wherein the vertices include the number of busses in the system and the edges include disconnect circuit branches connecting the individual vertices. A particular system configuration, selected by the system operator, determines the status (open or closed) of the various disconnect branches. A processor establishes an incident graph matrix, including positions of all the vertices and edges. The matrix is modified in accordance with graph theory and the condition of the disconnect switches. Graph operations are performed to produce a resulting matrix which defines vertices and the edges incident thereon into zones of protection. Fault analysis in the busline can then be performed in accordance with each zone of protection.

摘要： Current transformer (CT) secondary currents for the windings of a power transformer are used to produce a differential current. An operating current value is obtained from the differential current value. A restraining current value is obtained from processed winding current values. Second and fourth harmonic values of the differential current are obtained and are summed with a restraining current quantity which is a result of the restraining current multiplied by a slope characteristic factor. If the operating current value is greater than the sum of the restraining current quantity and the second and fourth harmonic values, an output signal is produced which may be used as a trip signal unless it is blocked by selected blocking signals generated by another portion of the system.

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.
