<span>Sustained growth in the demand with unprecedented investments transmission infrastructure resulted narrow operational margins for power system operators across globe. As a result, networks are operating near to stability limits. This has demanded electrical utilities explore new avenues control and protection of wide area systems. Present supervisory data acquisition/energy manageme...

The low voltage level synchrophasor measurement data are investigated to estimate the damping ratio and to detect any oscillation mode using Fast Fourier Transform (FFT) and Continuous Wavelet Transform (CWT). Complex Morlet (CM) is selected as a mother wavelet function considering its ability to reveal time and frequency localization simultaneously. A Two Area Four Machine System (TAFMS) model...

Power measurement systems, such as Phasor Measurement Unit (PMU) structures, require installation of special voltage and current instrument transformers connected to the energized conductor to collect data from the power line. While non-contacting methods of current monitoring are already well known and implemented, the contactless voltage monitoring is still lacking. This paper describes a tun...

In this paper, phasor measurement unit (PMU) data-based synchronous generator model identification is carried out using unscented Kalman filter (UKF). The identification not only gives the model of a synchronous generator’s swing dynamics, but also gives its turbine-governor model along with the primary and secondary frequency control block models. PMU measurements of active power and voltage m...

The concept of phasor measurement and its application in power system monitoring and control are introduced in this paper. The example of application of PMU in a Campus Wide Area Monitoring System (WAMS) is then elaborated. With the availability of synchrophasor data measurement, it makes possible to establish the power system monitoring by directly employing spectral analysis of power or phase...

<p>Fault identification in a power system is crucial. In recent days, there have been multiple microgrids connected to the system. And if many buses are connected, then need for an increase phasor measurement unit. By using optimization technique, number of unit PMUs can be reduced by placing them optimally. this paper, fault detection algorithm implemented with help particle swarm (PSO) ...

in this paper a new algorithm based on phasor measurements for estimating the thévenin equivalent (te) and system inertia constant is proposed. the method estimates the network te seen from a generator terminal and equivalent system inertia constant by means of phasor data that is available at phasor data concentrator (pdc) center. it is shown that the parameters of the te could be estimated at...
