Patent number: 9746511Abstract: Example implementations described herein are directed to detection of anomalous events and locations on the transmission power system using phasor management unit (PMU) data, which provides information to grid operators for online decision support. From the high-resolution time synchronized PMU data, the transient abnormal events can be monitored and locations can be disclosed to operators for remedy actions. Utilization of PMU information for such decision support compliments operation practices relying on supervisory control and data acquisition (SCADA) measurements at much lower data resolution. Accurate identification of event locations can further advise grid operators the root cause of disturbances and illuminate possible cascading failures. Implementations of the proposed technology may improve the resilience and reliability of the transmission power systems.Type: GrantFiled: November 25, 2015Date of Patent: August 29, 2017Assignee: Hitachi, Ltd.Inventors: Alex Wang, Hsiu-Khuern Tang, Bo Yang, Jun Yamazaki

Patent number: 8433795Abstract: An example embodiment of the present invention provides a process that uses IP flow information to selectively notify users of an application server of the server's unavailability. In the example embodiment, the process, which might run on a system comprising a router, monitors IP flow records as to dropped packets and learns that an application server has become unavailable. The process then uses the IP flow records to identify active users of the application server, for example, by passing a source IP address to a presence service. Once the process has identified an active user, the process determines a means of notification for the user, which might be through the presence service, and transmits a notification to the user as to the unavailability of the application server. In the example embodiment, the process transmits a later notification as to the availability of the application server, using reverse camp-on functionality.Type: GrantFiled: February 6, 2012Date of Patent: April 30, 2013Assignee: Cisco Technology, Inc.Inventors: Alex Wang, David Bainbridge, Xiaohui Zhou, Beecher Adams
