Field performance of ambient modal estimation in small signal stability
(IEEE, 2015)
Small signal stability is one focus of Wide Area Measurement Systems (WAMS). WAMS systems are becoming more widespread, driven by availability of synchrophasor data from Phasor Measurement Units (PMUs). In this paper, two ...
Improved event based method for harmonic impedance assessment
(IEEE, 2016)
The quantification of harmonic emission requires an accurate model of the network harmonic impedances. A number of techniques have been proposed for the assessment of the network harmonic impedances to be practical and ...
On the development of a power quality benchmarking model
(IEEE, 2009)
The development of a Power Quality (PQ) Benchmarking model is presented. Practical results are discussed to motivate the need of adding value to recorded PQ data by means of benchmarking PQ performance. The importance, ...
Towards PQ regulation in Southern Africa
(IEEE, 2009)
This paper discuss the regulation of Power Quality (PQ) in Southern Africa from a user perspective
An overview of the application of phasor measurement units (PMUs) and network coherent data in an interconnected power network: a case for Namibia
(Elsevier, 2017)
This paper presents the technological background, the structure of a time-stamp for network coherent data and the emerging documentation on the data requirements for applications making use of network coherent data. ...
The improvement of system damping by grid integration of PV energy sources
(IEEE, 2017)
The impact of static generators on power system small signal stability is evaluated by means of micro-synchrophasors collected in a distribution system using a class A Power Quality recorder that also functions as a Phasor ...
Where is the power of the IEEE 1459-2010?
(IEEE, 2014)
The integration of the IEEE 1459-2010 power definitions with the IEC 61000-4-30 PQ standard is investigated. A Class A PQ instrument, which record network coherent data with an absolute time uncertainty of less than 100 ...
Practical evaluation of voltage unbalance at a distribution transformer based on 50 Hz negative sequence active power
(IEEE, 2011)
The paper investigates the measurement and propagation of voltage unbalance at a distribution transformer. The relations between unbalance factors in voltage and current with the direction of negative sequence fundamental ...
Continuous harmonic impedance assessment using online measurements
(IEEE, 2015)
The quantification of harmonic emission requires an accurate representation of the network harmonic impedances. A number of techniques have been proposed to make the assessment of the network harmonic impedances practical ...
Real-time power system oscillation monitoring using synchrophasor measurements
(IEEE, 2015)
Inter-area oscillations impact negatively on power system stability and power transfer capability. Monitoring oscillations in real time can improve control of the power system. Synchrophasor data from Phasor Measurement ...
