Abstract
Disclosed herein are intelligent electronic devices configured for monitoring an electric power delivery system and for determining a plurality of configuration settings based on measurements from the electric power delivery system. An IED may identify a configuration event, obtain a plurality of electrical parameters associated with the configuration event, determine a plurality of configuration parameters from the electrical parameters, determine a plurality of configuration settings based on the configuration parameters, and apply the settings to the IED. The IED may also be configured to initiate the configuration event by opening a single pole of a multi-phase power line.
Claims23
A system for monitoring an electric power delivery system that includes a power line, comprising:
- a local intelligent electronic device (IED) in communication with a local portion of the power line obtaining local electric power system measurements;
- a remote IED in communication with a remote portion of the power line obtaining remote electric power system measurements;
- a communication system in communication with the local and remote IEDs for transmitting the local and remote power system measurements;
- a configuration event module configured to receive the local and remote power system measurements and identify a configuration event therefrom;
- a configuration parameters module configured to receive the local and remote power system measurements and determine a plurality of configuration parameters based thereon;
- and,
- a configuration settings module configured to calculate a plurality of IED configuration settings based on the plurality of configuration parameters.
A method for configuring an intelligent electronic device (IED) for protection of an electric power line of an electric power delivery system;
- comprising:
- a local IED obtaining local electric power delivery system measurements from a local portion of the electric power line;
- a remote IED obtaining remote electric power delivery system measurements from a remote portion of the electric power line;
- identifying a configuration event using the local electric power delivery system measurements;
- determining a plurality of configuration parameters based on the local and remote electric power delivery system measurements;
- calculating a plurality of IED configuration settings based on the plurality of configuration parameters.
An intelligent electronic device (IED) configured to monitor an electrical power line, the IED further configured to automatically determine a plurality of configuration parameters during a configuration event, the IED comprising:
- a data bus;
- a communications port configured to transmit and receive information with a data network, the communications port in communication with the data bus;
- a processor in communication with the data bus;
- a non-transitory computer-readable storage medium in communication with the data bus and comprising instructions that when executed cause the processor to:
- identify a configuration event;
- obtain a plurality of electrical parameters associated with the configuration event;
- determine a plurality of configuration parameters based upon the plurality of electrical parameters;
- automatically determine a plurality of configuration settings based upon the plurality of configuration parameters;
- and
- configure the IED based on the plurality of configuration settings.
