Synchrophasors for island detection
2012 38th IEEE Photovoltaic Specialists Conference, 2012Detection and prevention of unintentional islands powered by distributed generators like photovoltaics remains a key concern of utility protection engineers, especially in high-penetration and grid-support environments. These evolving circumstances dictate that new island detection tools are needed.

Cyber secure synchrophasor platform
2011 IEEE/PES Power Systems Conference and Exposition, 2011Phasor measurement units (PMUs) are rapidly being installed across the USA as part of the DOE Smart Grid Investment Grant (SGIG) programs. Within three years there are expected to be over 1000 PMUs installed by nine SGIG grantees. However, there will be many more installed in distribution networks to help accommodate intermittent power from rooftop ...

Virtual synchrophasor monitoring network
2012 IEEE International Conference on Power System Technology (POWERCON), 2012Synchrophasors are considered one of the most important measuring quantities in the future of power systems. The main reason of synchrophasor monitoring is to prevent or detect in advance events that may cause failure or even damages of the transmission network. That is why Phasor Measurement Units (PMU) getting increased attention nowadays.

Distribution-Level Synchrophasors Estimation
2018 20th National Power Systems Conference (NPSC), 2018Various time domain, frequency domain and time-frequency domain methods have been used in literature for the accurate phasor estimation in transmission-level PMUs. This paper assesses the suitability of three such methods, viz., Taylor Weighted Least Square (TWLS), Interpolated Discrete Fourier Transform (IpDFT) and Empirical Wavelet Transform (EWT ...

Real-world synchrophasor solutions
2009 62nd Annual Conference for Protective Relay Engineers, 2009Synchrophasors are no longer an academic curiosity. Today synchrophasors are providing solutions that otherwise would have been too expensive or too complicated to implement with traditional approaches. This paper examines ten synchrophasor applications being applied to monitor, visualize, and control electric power systems. 1.

An improved dynamic synchrophasor estimator
2012 IEEE International Energy Conference and Exhibition (ENERGYCON), 2012Accurate real-time measurement of the synchrophasor of an electric waveform is one of the many open challenges in future smart power grids. Indeed, monitoring, protection and control capabilities of electric energy transmission and distribution systems heavily depend on the performance of the employed Phasor Measurements Units (PMUs).

A new algorithm to compute fault synchrophasor from transient state synchrophasor in PDC
2013 IEEE Power & Energy Society General Meeting, 2013Synchrophasors are increasingly used in the wide area monitoring applications. Computational window lengths of the practical synchrophasor estimation filters are often multiple fundamental cycles long to achieve robustness. In many situations, the window length of the synchrophasor estimation filter is greater than the fault clearing time. In this case,

Oscillation monitoring system using synchrophasors
2009 IEEE Power & Energy Society General Meeting, 2009With the growing implementation of synchrophasors or PMUs across the power grid, it is now possible to observe and analyze system-wide dynamic phenomena in real-time. At Washington State University (WSU), we have been developing the framework of an Oscillation Monitoring System (OMS) for extracting the modal information of electromechanical ...
