A great deal of research has been done on the monitoring and analysis of power system events using wide-area frequency measurements. However, the events that have been explored so far mainly fall into the sphere of electrical disturbances of the power system itself, which include generation trips, load shedding, line trips, etc. Scarcely has the research touched upon how societal events, such as national...
Wide-area measurement systems (WAMS) enable the monitoring of bulk power systems providing deep insight into system dynamics. The North American frequency monitoring network (FNET) takes GPS-synchronized wide-area measurements in a low-cost, easily deployable manner at the 120 V distribution level. A situational awareness system has been implemented on the server located at Virginia Tech to detect...
It is very important to understand system dynamics during disturbances in order to improve control measures to ensure power system security and reliability. Power system disturbances are examined in this paper based on wide-area frequency data from a nation-wide frequency monitoring network (FNET). Frequency characteristics of events in three major North America power grids are investigated. Typical...
System-wide frequency is one of most important vital signs of power system. To better understand the dynamics of large power systems, wide-area, synchronized monitoring of system frequency is needed. The concept of an Internet based, real-time, GPS synchronized, wide-area frequency monitoring network (FNET) was proposed in 2000. Today, FNET consists of more than 30 frequency disturbance recorders...
Frequency dynamics is one of the most important measures of an electrical power system. To better understand power system dynamics, accurately measured wide-area frequency is needed. The concept of building an Internet based real-time GPS synchronized wide area frequency monitoring network (FNET) was proposed, and the actual system has been deployed. The FNET system consists of frequency disturbance...
