When disturbances occur in power grid, monitoring, control and protection systems are required to stop the grid degradation, restore it to a normal state, and hence minimize their effects. However, in wide area power grid resulting from large extension and interconnection with neighbor grids, classical systems based on local independent measurements and decisions are not able to consider the ov...

This paper presents critical survey along with the novel concept of smart power flow controller with Phasor Measurement Units (PMUs) signals for stability enhancement of a large power system. Also, the current status of Wide Area Measurement Systems (WAMS) and developments in real time applications of synchrophasor technology in power system has been adequately addressed. It has been noticed th...

Islanding detection needs are becoming a pivotal constituent of the power system, since penetration distributed generators in utility system is continually increasing. Accurate threshold setting an integral part island scheme inappropriate might cause hazardous situation. This study looked at islanding conditions as well two transient faults, such single line to ground fault and three-phase bal...

State estimation is an important tool for power system supervision and control and the related applications. Based on the redundant measurements taken in the network, state estimation provides the most likely state of the power system. Conventional measurements were collected by the SCADA system and the measurement chain did not allow measurement synchronization. A disadvantage is that due to t...

Electric power system operators make critical decisions based on remote measurements. If those measurements are compromised, it is possible to make decisions that could lead to critical consequences. Of particular concern are unobservable attacks where compromised measurements are not flagged as erroneous by bad data detection algorithms. The use of secure measurement devices, such as PMUs, is ...

In recent years, there has been growing interest of synchrophasor measurements like Phasor Measurement Units (PMUs) Power systems are now being gradually populated by PMU since they provide significant phasor information for the protection and control of power systems during normal and abnormal situations. There are several applications of PMUs, out of which state estimation is a widely used. T...

Phasor Measurement Unit’s (PMU) are power system devices which provide real time synchronized phasor measurements. Synchronization is achieved by same-time sampling of voltage and current waveforms by means of timing signals from the Global Positioning System Satellite (GPS). Synchronized phasor measurements make higher the standards of power system monitoring, control, and protection. Since PM...
