“Frequency” and the PMU standard
2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2021The Phasor Measurement Unit (PMU) has revolutionized power system management by providing high-resolution, time-stamped, spatial, and temporal measurements of the state of power systems. However, the standards defining the measured quantities have ambiguities that cause uncertainty, irreproducibility, and loss of interoperability during periods of ...

2020 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT), 2020
In this paper, we map the PMU data to a graph via the visibility algorithm to generate the PMU visibility graph. Applying complex network analysis to this graph unravels several hidden features in the PMU data. The applications of the PMU visibility graphs in the real power grid include anomaly detection, topology identification, and state estimation ...

Fractional Dynamics of PMU Data
IEEE Transactions on Smart Grid, 2021Novel dynamics are emerging in the power system due to the new Smart Grid (SG) environment. The high sampling rate of the Phasor Measurement Units (PMUs) enables them to capture the dynamic fluctuations in the power system measurements. Understanding the statistical and dynamic characteristics of the PMU data requires advanced data analytics techniques

PMU Location Determination in a Hybrid PMU-SCADA System
2020 12th International Conference on Information Technology and Electrical Engineering (ICITEE), 2020The accurate real-time state estimation is needed to perform real-time monitoring and control. However, the current power system uses SCADA technology as a tool for monitoring and control. SCADA existing measurement device has a few disadvantages: low accuracy, low sampling rate in measuring the measurements data, and asynchronous measurements between ...

Accurate phase calibration of PMUs and PMU calibrators
2016 Conference on Precision Electromagnetic Measurements (CPEM 2016), 2016A measurement setup is developed for accurate phase calibration of phasor measurement units (PMUs) and PMU calibrators. The measurement method is based on generating a reference signal with known phase with respect to a 1 pulse-per-second time reference using a stepped sine wave signal.

The PMU dynamic performance evaluation and the comparison of PMU standards
2012 IEEE Power and Energy Society General Meeting, 2012Synchronized phasor measurement is one of the most important information sources for smart transmission grid, which provides a new path for power system dynamic monitoring, analysis and control. Therefore whether the PMU (phasor measurement unit) can track the status of the power system, especially under the dynamic condition, is crucial.

A Brazilian PMU-WAMS pilot project: A methodology for PMU site selection
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017The stability of interconnected large power systems — like the Brazilian National Grid (SIN) — is directly compromised by weakly or not damped low frequency oscillations and transitory oscillations, these latter originated from large contingencies.

Verifying interoperability and application performance of PMUs and PMU-enabled IEDs
2012 IEEE Power and Energy Society General Meeting, 2012This paper presents a new test methodology for verifying the interoperability and application performance of PMUs and PMU-enabled IEDs at the device and system level. Two types of tests are defined to evaluate the performance of synchrophasor devices from two different aspects: design and application.
