Abstract: 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.

Abstract: A method for quantifying power quality events in an electrical system including a plurality of intelligent electronic devices (IEDs) includes processing electrical measurement data from or derived from energy-related signals captured by at least one first IED of the plurality of IEDs to identify a power quality event at a first point of installation of the at least one first IED in the electrical system. An impact of the power quality event at a second point of installation in the electrical system is determined based on an evaluation of electrical measurement data from or derived from energy-related signals captured by at least one second IED of the plurality of IEDs at the second point of installation proximate to a determined time of occurrence of the power quality event at the first point of installation.

Abstract: A method of acquiring data and performing calculations on the data using a provider service. A provider ticket service (PTS) receives tickets from one or more clients. Each ticket includes a calculation identifier and a payload. The calculation identifier identifies a calculation to be performed using information in the payload. The PTS associates a unique ticket identifier with each ticket. A ticket manager submits a selected ticket from the PTS to a provider host service (PHS), which determines which provider is to perform the calculation identified by the selected ticket by inspecting provider identification information in the selected ticket. The PHS launches a provider host thread (PHT) that invokes the provider determined to perform the calculation identified by the calculation identifier of the selected ticket. The provider performs the calculation and returns its result to the PHS, which passes the result back to the PTS, which returns the result to the requesting client.

Abstract: A system and methods for creating a logical profile for physical devices in a system to interface with a monitoring system is disclosed. A profile identity is selected. A plurality of physical devices from the system is selected. The physical devices such as a meter or a circuit breaker include an output or an input. An input or output is classified for at least one of the plurality of selected physical devices as a tag. The plurality of selected physical devices are represented to the monitoring system by the profile identity and the at least one tag of the selected physical devices.
