Traceability of calibration for Phasor Measurement Unit

2012 IEEE Power and Energy Society General Meeting, 2012
IEEE 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 ...

Phasor measurement unit using GPRS wireless connectivity

2011 IEEE PES CONFERENCE ON INNOVATIVE SMART GRID TECHNOLOGIES LATIN AMERICA (ISGT LA), 2011
This paper describes the development of a phasor measurement unit using data wireless transmission via GPRS. The detailed process in the design and construction of the prototype and the difficulties faced at different stages are presented. The results are finally evaluated using the Total Vector Error (TVE) calculated for each of the testing designs.

End-to-End Remote Field Testing of Phasor Measurement Units Using Phasor Measurement Unit Performance Analyzer Test Suite

IEEE Transactions on Industry Applications, 2020
Phasor measurement unit (PMU) testing is desired to ensure the continued power system monitoring and the maneuvering precision of synchrophasor-based control. IEEE Std C37.118 and IEEE synchrophasor measurement test suite specification (TSS) clarify the different requirements for both steady-state and dynamic test scenarios with varied error ranges ...

Calibration of phasor measurement unit at NIST

2012 Conference on Precision electromagnetic Measurements, 2012
Phasor 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.

Calibration of Phasor Measurement Unit at NIST

IEEE Transactions on Instrumentation and Measurement, 2013
This paper describes the basic operating principles of Phasor Measurement Units (PMUs) and their time requirements to estimate absolute phase angles. A National Institute of Standards and Technology (NIST) PMU calibration system that tests PMU performance necessary to meet the IEEE synchrophasor standard requirements is discussed.

Voltage stability analysis using phasor measurement unit

2017 Recent Developments in Control, Automation & Power Engineering (RDCAPE), 2017
This paper provides a brief knowledge of the voltage stability and its measure is used in the state estimation (SE). Changes in voltage value occurs due to the changes in the load. Its evaluation has been done by varying load and for different load cases and varied voltage value is noted. To perform SE, Weighted Least Square (WLS) method is used. Since

Multistage optimal placement of phasor measurement unit

2015 International Conference on Energy, Power and Environment: Towards Sustainable Growth (ICEPE), 2015
This paper is concerned about the optimal allocation of Phasor Measurement Units and at the same time ensuring the complete network observability with the available Phasor Measurement Units. Due to large interconnection of the power system it is not possible to allocate Phasor Measurement Units at strategic location in one go.
