摘要:
Systems and methods for characterizing a device that operated to clear a fault in a power line, such as a power distribution system feeder, are disclosed. Characterizing the device may include receiving measured data corresponding to a current measured along the feeder proximate a substation bus, determining from the measured data that a fault has occurred in at least one phase and has been cleared, subtracting reference data from the measured data to estimate residual fault data, and estimating from the residual fault data a characteristic of the device that operated to clear the fault. The systems may include an Intelligent Electronic Device (IED) and a processor linked to the IED.

Systems and methods for classifying power line events are disclosed. Classifying power line events may include receiving measured data corresponding to a signal measured on a power line, such as proximate a substation bus or along the power line, determining from the measured data that the power line event has occurred, extracting at least one event feature from the measured data, and determining at least partially from the at least one event feature at least one probable classification for the power line event. The systems may include an Intelligent Electronic Device (IED) connected to the power line and a processor linked to the IED.

Systems and methods for power line event zone identification are disclosed. Power line event zone identification may include receiving measured data corresponding to a signal measured on a power line, determining from the measured data that a power line event has occurred, and identifying a probable one of at least two monitoring zones in which the power line event occurred. The at least two monitoring zones may be defined for an Intelligent Electronic Device (IED). The systems may include an IED connected to the power line and a processor linked to the IED.

An object that is not linked to a root object of a data model is identified. A first instruction comprising a fingerprint and a request to delete the object from memory is transmitted to a plurality of user devices. A second instruction to undo the first instruction is received from one of the plurality of user devices, and, in response to the second instruction, a third instruction comprising the fingerprint and a request to execute and delete any instruction that includes the fingerprint is transmitted to the plurality of user devices.

摘要:
A remote procedure call handler generated by a third party is hosted by a server, wherein the remote procedure call handler is configured to receive, from an end user device, a remote procedure call relating to a document associated with by a third party application. A remote procedure call relating to the document is received from a first user device, via interframe communication. The document is updated by the remote procedure call handler, based on the remote procedure call. An event notification message informing a second end user device of the update to the document is transmitted to a second user device, via interframe communication.
