DFT-Based Identification of Oscillation Modes from PMU Data Using an Exponential Window Function

Energies, 2019
The characteristics of oscillation modes, such as interarea, regional, and subsynchronous modes, can vary during a power system fault, which can cause switching and control actions in the power system.

Improving frequency and ROCOF accuracy during faults, for P class Phasor Measurement Units [PDF]

, 2013
Many aspects of Phasor Measurement Unit (PMU) performance are tested using the existing (and evolving) IEEE C37.118 standard. However, at present the reaction of PMUs to power network faults is not assessed under C37.118.

Optimal PMUs placement considering ZIBs and single line and PMUs outages

AIMS Energy, 2020
Phasor measurement unit (PMU) is among the most important measurement devices in modern power systems. It measures the voltage and current phasors which have both magnitude and phase angle using a common timing reference. These measurements are utilized in real time applications of electrical power systems. The main drawback of PMUs is its high cost so
