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

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 ...

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.

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.

On the accuracy specifications of Phasor Measurement Units
2010 IEEE Instrumentation & Measurement Technology Conference Proceedings, 2010A critical overview of the accuracy specifications of Phasor Measurement Units in the measurement of synchrophasors is presented in this work. The focus is both on the possible ambiguity arising from the definition of Total Vector Error (TVE), provided by the IEEE Standard C37.118-2005, and on the lack of homogeneity in the information provided by PMU ...

Phasor Measurement Unit Diagnosing
2018Based on the global navigation system timestamp an equipment is applied to synchronize the measurement moment in various power buses, which are remote from each other, to measure the current and voltage phasors for the power system control. It is named phasor measurement unit (PMU).
