Impact of Causality on Performance of Phasor Measurement Unit Algorithms
IEEE Transactions on Power Systems, 2018Most existing phasor measurement units (PMUs) are noncausal PMUs and they compensate for the group delay in PMU applications by shifting time stamps, which may result in high latency that will impair performance of PMU applications.

Comparative testing of synchronized phasor measurement units
IEEE Power Engineering Society General Meeting, 2004., 2005This work reports the result of a comparative testing done on four phasor measurement units (PMU) from different manufacturers. Phase shift and attenuation at fundamental frequency, performance under system balanced and unbalanced conditions and performance under system variable frequency are the issues addressed for this comparative assessment.

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

Power system applications for phasor measurement units
IEEE Computer Applications in Power, 1994State-of-the-art technology now permits measurement and analysis of power system performance on a scale not previously possible. Synchronized sampling, derived from the GPS (Global Positioning System), and high accuracy sigma-delta analog-to-digital converters form the basis for a system that can measure the state of the power system at a given instant

Diakoptic State Estimation Using Phasor Measurement Units
IEEE Transactions on Power Systems, 2008This paper presents a diakoptic-based distributed state estimation (SE) algorithm suitable for large-scale power systems. In the proposed approach the large-scale power system is divided into a certain number of subsystems by removing tie line measurements. Based on diakoptic theory, the SE problem is then partitioned into a number of subproblems which
