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).

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 ...

Traceability of calibration for Phasor Measurement Unit
2012 IEEE Power and Energy Society General Meeting, 2012IEEE Standard C37.118.1 defines requirements for the measurement and determination of a Phasor Measurement Unit (PMU). The PMUs must be tested to ensure that all PMUs on the power grid behave the same. In order to meet the requirement of PMU within specified uncertainty, the PMU calibration systems or calibrators must be traceable to known reference ...

Testing and enhancement of the dynamic performance of a Phasor measurement unit
2015 IEEE Power & Energy Society General Meeting, 2014Phasor measurement units (PMUs) provide the basis for synchrophasor measurements, which are good data sources for capturing power system dynamic behavior. The recently published IEEE Standard C37.118.1-2011 characterizes the dynamic performance of synchrophasor measurements with two performance class filters: P-class and M-class.

The Evaluation of Phasor Measurement Units and Their Dynamic Behavior Analysis
IEEE Transactions on Instrumentation and Measurement, 2013The dynamic behavior of phasor measurement units (PMUs) is not only the key point to dynamic phasor algorithm improvement but also the basis for the successful implementation of PMUs in power system dynamic security monitoring and control. In this paper, the dynamic performance of PMUs is evaluated, and their dynamic behaviors are analyzed.

Micro Phasor Measurement Unit Phasor Estimation by off-Nominal Frequency
2018 IEEE International Conference on Smart Energy Grid Engineering (SEGE), 2018Due to the high sampling rate of the power signals by Micro Phasor Measurement Units (μPMUs) tight restrictions on computing time of different algorithms are imposed. Especially when dealing with Phasor estimation by off-nominal frequency. Sampling the power signal with a frequency which is a multiple of the instantaneous power frequency is used to fix

Phasor measurement units for the distribution grid: Necessity and benefits
2013 IEEE PES Innovative Smart Grid Technologies Conference (ISGT), 2013High penetration levels of distributed energy resources (DER) and active loads in the distribution grid can change the traditional grid from a slower-changing radial network to a multi-source network with faster dynamics. Although overall system reliability and quality of supply can in principle be improved under this paradigm, new control and ...
