Source Impedance Estimation

摘要

Disclosed herein are a variety of systems and methods for estimating a source impedance value. One embodiment may include an intelligent electronic device (IED) configured to interface with an electric power distribution system. The IED may include a communications interface, a processor, and a non-transitory computer-readable storage medium. The computer-readable storage medium may include software instructions executable on the processor that enable the IED to identify a source impedance modeling event at a node in the power distribution system. The software instructions may further enable the IED to receive a plurality of measurements representing an electrical condition at the node prior to the source impedance modeling event and subsequent to the source impedance modeling event. The IED may calculate a source impedance value based on the first plurality of measurements at the node. Based on the source impedance value, a control action may be generated.

1. An intelligent electronic device (IED) configured to interface with an electric power distribution system, comprising:
a bus; a communications interface in communication with the bus; a processor in communication with the bus; and a non-transitory computer-readable storage medium in communication with the bus, comprising:
software instructions executable on the processor that enable the IED to:
identify a first source impedance modeling event at a first node in the electric power distribution system;receive a first plurality of measurements representing a first electrical condition at the first node prior to the first source impedance modeling event and subsequent to the first source impedance modeling event;calculate a first source impedance value based on the first plurality of measurements at the first node;generate a first control action based at least in part upon the first source impedance value and a control strategy; andtransmit the first control action via the communications interface.
