摘要： A method to automatically optimize waveform captures from an electrical system includes capturing at least one energy-related waveform using at least one Intelligent Electronic Device (IED) in the electrical system. The at least one captured energy-related waveform is analyzed to determine if the at least one captured energy-related waveform is capable of being compressed, while maintaining relevant attributes for characterization, analysis and/or other use. In response to determining the at least one captured energy-related waveform is capable of being compressed, while maintaining relevant attributes for characterization, analysis, and/or use, the at least one captured energy-related waveform may be compressed using at least one compression technique to generate at least one compressed energy-related waveform. One or more actions may be taken based on or using the at least one compressed energy-related waveform.

摘要： Systems and methods for improving identification of issues associated with detecting anomalous conditions (e.g., electrical transient voltages) in electrical systems are disclosed herein. The anomalous conditions may be difficult to discern, for example, due to metering constraints of Intelligent Electronic Devices (IEDs) responsible for identifying the anomalous conditions in the electrical systems. In one aspect of this disclosure, a method to automatically identify metering constraints of one or more IEDs in an electrical system includes capturing at least one energy-related waveform using at least one of the IEDs in the electrical system, and processing electrical measurement data from, or derived from, the at least one energy-related waveform to identify anomalous characteristics in the electrical system. The anomalous characteristics may be indicative of an anomalous condition in the electrical system, for example. In response to identifying anomalous characteristics in the electrical measurement data, an event constraint model is built based on or by using the identified anomalous characteristics. Once built, the event constraint model is analyzed to determine if the at least one energy-related waveform is being adequately captured by the at least one of the IEDs. In response to determining the at least one energy-related waveform is not adequately captured, one or more actions may be taken to address the capturing inadequacy.

摘要： A method for characterizing power quality events in an electrical system includes deriving electrical measurement data for at least one first virtual meter in an electrical system from (a) electrical measurement data from or derived from energy-related signals captured by at least one first IED in the electrical system, and (b) electrical measurement data from or derived from energy-related signals captured by at least one second IED in the electrical system. In embodiments, the at least one first IED is installed at a first metering point in the electrical system, the at least one second IED is installed at a second metering point in the electrical system, and the at least one first virtual meter is derived or located at a third metering point in the electrical system. The derived electrical measurement data may be used to generate or update a dynamic tolerance curve associated with the third metering point.

摘要： Systems and methods for managing voltage event alarms in an electrical system are provided. In one aspect of this disclosure, a method for managing voltage event alarms in an electrical system includes processing electrical measurement data from, or derived from, energy-related signals captured by at least one intelligent electronic device (IED) to identify an anomalous voltage condition at a point of installation in the electrical system. The anomalous voltage condition may correspond, for example, to a measured IED voltage being above or greater than one or more upper alarm thresholds or below or less than one or more lower alarm thresholds. The method also includes determining if the electrical system is affected by the identified anomalous voltage condition. In response to determining that the electrical system is affected by the identified anomalous voltage condition, at least one of a plurality of criteria may be chosen to adjust at least one of the upper alarm thresholds and/or at least one of the lower alarm thresholds.

摘要： A method for reducing and/or managing energy-related stress in an electrical system includes processing electrical measurement data from or derived from energy-related signals captured by at least one intelligent electronic device (IED) in the electrical system to identify and track at least one energy-related transient in the electrical system. An impact of the at least one energy-related transient on equipment in the electrical system is quantified, and one or more transient-related alarms are generated in response to the impact of the at least one energy-related transient being near, within or above a predetermined range of the stress tolerance of the equipment. The transient-related alarms are prioritized based in part on at least one of the stress tolerance of the equipment, the stress associated with one or more transient events, and accumulated energy-related stress on the equipment. One or more actions are taken in the electrical system in response to the transient-related alarms to reduce energy-related stress on the equipment in the electrical system.

A method in accordance with one embodiment of this disclosure includes capturing or deriving at least one energy-related signal using one or more Intelligent Electronic Devices in an electrical system, and processing electrical measurement data from, or derived from, the at least one energy-related signal to identify anomalous characteristics in the electrical system. In response to identifying the anomalous characteristics in the electrical system, a degree of voltage phase jump and a voltage sag magnitude may be determined based on or using the identified anomalous characteristics. The degree of the voltage phase jump and the voltage sag magnitude may be displayed on at least one phasor diagram, and the at least one phasor diagram may be analyzed to determine most optimal/cost-effective apparatus(es) to mitigate at least one of the identified anomalous characteristics.
