Two-Stage Fault Location Detection Using PMU Voltage Measurements in Transmission Networks
… reduce the outage time and improve the system reliability [1]. With the development of Wide Area Measurement System (WAMS) and Phasor Measurement Unit (PMU), various fault location algorithms have been proposed. The purpose of this work is to determine, modify and test the most …

Propagation of Electromechanical Disturbances across Large Interconnected Power Systems and Extraction of Associated Modal Content from Measurement Data
Changes in power system operating conditions cause dynamic changes in angle and frequency. These disturbances propagate throughout the system area with finite speed. This propagation takes the form of a traveling wave whose arrival time at a particular point in the system can be observed using a …

Describing functions for information channels subject to packet loss and quantization
… vehicle (AUV) coordination and navigation, Wide Area Measurement System (WAMS) control of power grids, and automobile networked subsystems control. As one would expect, demand on throughput grows to fill the available channel capacity; in a clean short-range RF setting, entire images may be …

A Local Measurement Based Protection Methodology for Initiating Controlled Islanding in Power Systems
Despite layers of protection at work, power systems still have experienced major blackouts in the past due to cascading outages. Hence, preventing the cascading outage holds the key to the prevention of such blackouts in the future. To address this problem, researchers have proposed controlled …

WAMS-based Intelligent Load Shedding Scheme for Preventing Cascading Blackouts
… If the mismatch is not rectified quickly, the system may disintegrate into multiple islands. Though the Automatic Generation Controls (AGC) perform well in correcting frequency deviation over a period of minutes, they are ineffective during a rolling blackout. While traditional Under Frequency …
