The pulse coupled phasor measurement units
2014 IEEE International Conference on Smart Grid Communications (SmartGridComm), 2014We propose a cross-layer sensor network architecture to convert measurements acquired by a population of sampling devices, into synchronous sensor array measurements, using a network synchronization protocol that is inspired by the dynamics of pulse coupled oscillators (PCO).

Precision measurement system for the calibration of Phasor Measurement Units
2016 Conference on Precision Electromagnetic Measurements (CPEM 2016), 2016Phasor measurement units (PMUs) are used for monitoring, protection, and control of smart grids. Characterization of PMUs to national standards of measurement is important to assure reliability and consistency of PMUs across the industry and is required by documentary standards.

Testing phasor measurement units
IET 9th International Conference on Developments in Power Systems Protection (DPSP 2008), 2008Phasor measurement units (PMUs) are getting increasingly popular. Major incidents in the near past, such as the big blackouts in 2003 in the northeast of the USA and in Italy, have raised the interest in all means that support the observation of the condition of the electrical power network, assessing system stability, and predicting problems. PMUs are

A Brief Review on Synchro Phasor Technology and Phasor Measurement Unit
2020In power system monitoring, supervisory control and data acquisition (SCADA) system has played an important role by computing the voltage and current signal for a local area. However, when quicker response is needed, phasor measurement unit (PMU) serves as an effective alternative owing to its faster reporting rate. In this paper, a brief review on PMU

PMUs [phasor measurement unit]
IEEE Potentials, 1994In the spring of 1993, a major new 500 kV transmission line was put in service in Northern California. Test engineers initiated a series of artificial short-circuit faults to test the line installation. As an experiment, the steady-state and transient responses of the power system were recorded.

Phasor measurement unit placement Algorithm
2009 IEEE Power & Energy Society General Meeting, 2009The importance of having phasor measurement units or PMUs in an electric grid is widely recognized. However, the number of PMUs on a large system is limited by cost and the placement of PMUs must be addressed. The main objective of this research is to create an algorithm to identify buses that are the best candidates for PMU placement based on certain ...

Calibration of phasor measurement unit at NIST
2012 Conference on Precision electromagnetic Measurements, 2012Phasor Measurement Units (PMUs) are being deployed on electric power grids to monitor their static and dynamic behavior. The information they gather is important to detect problems on these systems and to prevent blackouts. The PMUs require time synchronization of the data taken across the grids.
