Abstract: A method is provided for handling synchrophasor measurements relating to an electrical power system. The method includes: (a) acquiring a plurality of synchrophasor measurements containing data representing at least one power system event; (b) inserting and storing the event related synchrophasor measurements in a database as a partitioned binary large object (BLOB); (c) reading and transferring the synchrophasor measurements related to a user selected current or historical event from the database to a client computer partition by partition; and (d) processing the event data at the client computer on a partition-by-partition basis such that the client computer will be able to start a replay of the event replay as soon as processing of the first partition of the event BLOB data is completed.

Abstract: A phasor measurement unit and method including a transducer for transduction measurement of an electrical characteristic of a current carrying element in electrical power generation or distribution systems, the transducer generating a transducer output signal representative of the electrical characteristic; an amplifier receiving the transducer output signal and generating an amplifier output signal; a filter receiving the amplifier output signal, low pass filtering the amplifier output signal, and generating a filter output signal; an analog to digital converter receiving the filter output signal and generating a digital output signal; and a processor receiving the digital output signal, calculating phasor data from the digital output signal and generating a data output signal, wherein the calculated phasor data is at least as accurate as phasor data from a phasor measurement unit or a frequency data recorder having a transducer for nontransduction measurement of the same electrical characteristic.

Abstract: A real-time, wide-area power system monitoring and visualization system is provided, including comprising an application database adapted to contain a synchronized data object queue and configuration data; a web service; an event-triggered data archive service; an event database; and a smart client visualization application adapted to commence web service with the application database and the event database.

Abstract: A system for scheduling, changing, and maintaining an outage schedule includes a data entry module adapted to allow a user to enter data pertaining to an outage, a pre-defined database containing transaction rules to define transaction flows, a processing module, and a display module. The processing module is adapted to process the data entered into the data entry module and the transaction rules provided in the pre-defined database. The display module receives processed data from the processing module, transforms the processed data into visual information representative of the processed data, and displays the visual information on a display of a computing device.
