NDZ of an anti-islanding protection with ROCOF threshold

, 2017
International audienceABSTRACTUsing the rate of change of frequency (ROCOF) to detectundesired islanding in distribution networks is alreadydone in a few countries of Europe and is considered apossibility in some others.

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

, 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.

PMU-Based ROCOF Measurements: Uncertainty Limits and Metrological Significance in Power System Applications

In modern power systems, the Rate-of-Change-of-Frequency (ROCOF) may be largely employed in Wide Area Monitoring, Protection and Control (WAMPAC) applications. However, a standard approach towards ROCOF measurements is still missing.

Compressive Sensing Taylor-Fourier and Windowing Approach for Synchronized Phasor, Frequency and ROCOF Measurements

, 2021
Modern distribution networks are characterized by higher distortion and wider variability of voltages and currents. Accurate synchrophasor, frequency and ROCOF measurements thus ask for new techniques trying to reduce latency while limiting the impact of

Space Vector Taylor–Fourier Models for Synchrophasor, Frequency, and ROCOF Measurements in Three-Phase Systems [PDF]

, 2019
Taylor-Fourier (TF) filters represent a powerful tool to design phasor measurement unit (PMU) algorithms able to estimate synchrophasor, frequency, and rate of change of frequency (ROCOF).

Under Frequency Load Shedding based on PMU Estimates of Frequency and ROCOF

, 2018
The paper describes a local under-frequency load shedding and load restoration scheme, that exploits frequency and Rate-of-Change-of-Frequency (ROCOF) measurements produced by Phasor Measurement Units (PMUs) as detectors of a large contingency. The paper
