The Design of a Low Cost Phasor Measurement Unit

Energies, 2019
The widespread diffusion of Phasor Measurement Units (PMUs) is a becoming a need for the development of the “smartness” of power systems. However, PMU with accuracy compliant to the standard Institute of Electrical and Electronics Engineers (IEEE) C37 ...

Towards Artificial Intelligence Hardware With 3D Integrated Ferroelectric Transistors

Small, EarlyView.
Modern AI workloads demand hardware that mitigates the data‐movement bottleneck of von Neumann architectures. Here, we demonstrate a 4‐tier monolithic 3D (M3D) platform vertically integrating IGZO access transistors with Hf₀.5Zr₀.5O2 ferroelectric FETs.

Classification of Broadband Oscillations Using Wavelet Convolution and Multi‐Channel Attention Network

Energy Internet, EarlyView.
ABSTRACT Accurate identification of broadband oscillation types is a prerequisite for implementing appropriate control strategies. The strongly nonlinear, nonstationary and multi‐modal characteristics of broadband oscillation signals impose higher demands on identification methods. Practical applications face challenges such as coupling effects between

The amended standard C37.118.1a and its implications for frequency-tracking m-class Phasor Measurement Units (PMUs) [PDF]

2014 IEEE International Workshop on Applied Measurements for Power Systems Proceedings (AMPS), 2014
The new amendment to the Phasor Measurement Unit (PMU) standard C37.118.1a makes several significant changes, compared to the standard C37.118.1 (2011). This paper highlights some of the most important changes, with a particular emphasis applied to how those changes relate to the way that a frequency-tracking PMU (Phasor Measurement Unit) algorithm ...
