Synchronized phasor measurement systems are being widely used around the world and have become essential elements in evolution of operation large electrical power (EPS). These systems, called Phasor Measurement Units (PMUs), capable recording communicating dynamic data from EPSs a synchronized way by GPS with high sampling rate, generate huge set that, among many applications, has capacity to d...

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...

<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...

Voltage stability is one of the most important factors in maintaining reliable operation of power systems. When a disturbance occurs in the power system, it usually causes instabilities and sometimes leads to voltage collapse (VC). To avoid such problems, a novel approach called Vector Analysis (VA) is proposed that exploits a new instability detection index to provide wide area voltage stabili...
