Filters for M class phasor measurement units [PDF]

, 2012
The new standard C37.118.1 lays down strict performance limits for phasor measurement units (PMUs) under steady-state and dynamic conditions. Reference algorithms are also presented for the P (performance) and M (measurement) class PMUs.

Voltage Stability Index Calculation by Hybrid State Estimation Based on Multi Objective Optimal Phasor Measurement Unit Placement

Energies, 2019
Operation of a power system close to the voltage stability limit due to increasing of load demand and limited power sources may result in disastrous economic loss with voltage collapse of the entire power system.

Fault Location in Distribution Network Based on Phasor Measurement Units (PMU) [PDF]

The Scientific Bulletin of Electrical Engineering Faculty, 2019
AbstractNowadays, phasor measurement units have many applications in the power network. Fault location using the network’s impedance matrix and phasor measurement units (PMU) is a subject that has been recently brought to the location light. In this research, we review the effect of the increased number of PMUs on the precision of the fault location ...

Phasor measurement units, WAMS, and their applications in protection and control of power systems

Journal of Modern Power Systems and Clean Energy, 2018
The paper provides a short history of the phasor measurement unit (PMU) concept. The origin of PMU is traced to the work on developing computer based distance relay using symmetrical component theory.

Performance Analysis of Generator Dynamic State Estimation under Uncertain Measurement

Zhongguo dianli, 2020
Random errors are unavoidable in phasor measurement unit (PMU), and the PMU measurement data may be uncertain in actual power system, such as delay, reordering or even missing.

P-class phasor measurement unit algorithms using adaptive filtering to enhance accuracy at off-nominal frequencies [PDF]

, 2011
While the present standard C.37.118-2005 for Phasor Measurement Units (PMUs) requires testing only at steady-state conditions, proposed new versions of the standard require much more stringent testing, involving frequency ramps and off-nominal frequency ...

Experimental test of PMU measurement errors and the impact on load model parameter identification

IET Generation, Transmission & Distribution, 2020
The results of ambient signals‐based load modelling are more sensitive to phasor measurement unit (PMU) measurement errors due to the relatively smaller disturbance magnitudes of ambient signals.
