Recording of operating parameters of an intelligent electronic device

摘要

The present disclosure provides systems and methods for recording operating parameters of an intelligent electronic device (IED). A system may include a parameter acquisition module, a parameter storage module, and a memory management module. The parameter acquisition module may be configured to periodically obtain operating parameters of an IED at a first interval. The first interval may have a first time length to provide a first resolution of operation of the IED. The parameter storage module may be configured to store the operating parameters. The memory management module may be configured to delete, outside a first resolution period, a first portion of the operating parameters while maintaining a second portion of the operating parameters. The second portion may include operating parameters for each of a second interval. The second interval may have a second time length to provide a reduced second resolution of the operation of the IED.

1. A system for recording operating parameters of an intelligent electronic device (IED) comprising:
an IED operating within an electric power delivery system, configured to obtain electric power system operating parameters and configured to record electric power system operating parameters and IED operating parameters; and a record module comprising:
a parameter acquisition module configured to continuously obtain IED operating parameters of the IED at a first resolution having a first interval having a first time length;a parameter storage module configured to store the obtained IED operating parameters to provide stored IED operating parameters at the first resolution; anda memory management module configured to delete, outside a first resolution period, a first portion of the IED operating parameters while maintaining a second portion of the IED operating parameters, wherein the second portion comprises IED operating parameters for each second interval having a second time length to provide a reduced second resolution of the operation of the IED;wherein the memory management module is further configured to identify an IED event and to delete outside of a third interval a third portion of the IED operating parameters while maintaining the IED operating parameters for the third interval associated with the IED event, the third interval having a third time length;wherein the parameter storage module is further configured to store the IED operating parameters at the second resolution and the IED operating parameters for the third interval associated with the IED event.
