摘要： A method for analyzing effects of electrical perturbations on equipment in an electrical system includes processing energy-related signals from at least one intelligent electronic device in the electrical system to identify an electrical perturbation in the electrical system. An end time of the electrical perturbation may be determined, and electrical measurement data from prior to, during and/or after the end time of the electrical perturbation may be analyzed to identify and quantify the effects of the electrical perturbation on equipment in the electrical system. The effects may include, for example, equipment restarts/re-energizations due to the electrical perturbation. One or more actions may be taken or performed to reduce the effects of the electrical perturbation and extend the life of the equipment. The actions may include, for example, at least one of communicating the equipment restarts/re-energizations and controlling at least one component in the electrical system.

摘要： A method for automatically aligning measured power-related data in a power monitoring system to a common reference point. A conductor in a power delivery system is modeled according to an equivalent pi model of a transmission line that is characterized by model parameters. The conductor is monitored on both ends by a reference monitoring device and a second monitoring device. The voltage and current are measured in either the reference monitoring device or the second monitoring device and a phase shift offset between the voltages or currents at the two devices is calculated. The calculated phase shift offset corresponds to a temporal delay between events observed at the pair of devices, and calculating and storing the phase shift offset allows a power monitoring system controller to more accurately align data received from monitoring devices.

摘要： A method of automatically identifying whether intelligent electronic devices (IEDs) in a power monitoring system are in multiple electrical grids. A controller sends an instruction to each IED in a predetermined time sequence such that each IED receives the instruction at a different time, commanding each IED to begin logging variation data indicative of frequency variations in a current/voltage signal monitored by the IED and to send the variation data to the controller and an associated cycle count of a point in the current/voltage signal. The controller receives the variation data and associated cycle count and determines a peak correlation using a data alignment algorithm on IED pair combinations. If the IEDs are on the same electrical grid, the peak correlations should occur at cycle count offsets that match the order that the IEDs received the instruction. Any discrepancies in the expected order of peak correlations are flagged, and the corresponding IEDs are determined to be on different grids.

摘要： Systems and methods for evaluating the stability of an islanded electrical system (112) (off-grid) using high-speed frequency measurements of the electrical signal supplied by an alternate power source (110) in the islanded electrical system (112). Additional inputs may include status signals from an automatic transfer switch (104), a generator (106), and loads (130, 132) within the islanded electrical system (112). The high-speed frequency measurements (108a) have a resolution sufficient to enable analysis of any combination of the frequency magnitude (e.g., sudden increase), frequency slew rate (e.g., frequency rate of change), frequency rate of recovery (e.g., frequency recovery time), or frequency oscillations (e.g., frequency ringing around the nominal value before settling) to indicate the presence of an actual or impending instability of the islanded electrical system. The frequency referred to herein corresponds to the frequency at which an alternating current supplied by the alternate power source is cycling.

摘要： A method for analyzing power quality events in an electrical system includes processing electrical measurement data from or derived from energy-related signals captured by at least one metering device in the electrical system to generate at least one dynamic tolerance curve. Each dynamic tolerance curve of the at least one dynamic tolerance curve characterizes a response characteristic of the electrical system at a respective metering point in the electrical system. The method also includes analyzing the at least one dynamic tolerance curve to identify special cases which require further evaluation(s)/clarification to be discernable and/or actionable. The at least one dynamic tolerance curve may be regenerated or updated, and/or new or additional dynamic tolerance curves may be generated, to provide the further clarification. One or more actions affecting at least one component in the electrical system may be performed in response to an analysis of the curve(s).

摘要： An automated hierarchy classification algorithm (300) that searches for a child monitoring device's parent in a utility monitoring system (102) by segmenting the device data measured by a given device pair and calculating a segment correlation coefficient for each data segment. Devices to be placed in the hierarchy are filtered by calculating (304) the variance of their device data and eliminating devices with a low variance (306, 308). Devices are ranked by computing the sum of squares of their device data and ordering the devices accordingly from highest to lowest. The device data is segmented and segment correlation coefficients are averaged to produce an overall correlation coefficient. Criteria are evaluated to determine whether a device pair is linked. A correlation coefficient is calculated using the complete data series of a device pair (316), and the solution produced by this approach is compared (322) with the solution produced by segmenting the device data (314). If the solutions disagree, a likely candidate is determined (324) from a fuzzy logic module (120).
