AEM

Automated Event Miner

Utilities and ISO's typically retain years of historical synchrophasor data amounting to terabytes of stored information. However as with most archived data it's value can only be attainted if it can be utilized to produce meaningful information that can optimize your future operations. Identifying this exact need, EPG launches Automated Event Miner. A powerful tool which can intelligently mine your data to extract information to assess grid performance such as how many events occured, when and where they occured and how severe were they? Knowing this information can help you identify potential equipment failure and identify weak spots in the grid to guide capital investments and optimize your operating procedures. Some highlights of AEM include:


  • • AEM has been extentively used to generate reports for CAISO, SPP, ERCOT, GETCO, SRLDC and OETC
  • • AEM identifies Oscillations, genertion and load trips, faults and low voltage events.
  • • AEM mreasures anomalies and device calibration issues
  • • AEM offers data quality assessment summaries
  • • AEM offers automated report generation
  • • AEM has a intuitive, easy to use interface which can be used right out of the box

About EPG

Electric Power Group, LLC (EPG) has been pioneering the development and deployment of synchro-phasor technologies since 2000. Our principals have extensive experience in running and managing utility grids, investigating root causes of major blackouts (WECC 1996, EI 2003), and leveraging this deep domain knowledge to develop industry leading synchrophasor technology applications for wide area real time monitoring, visualization and situational awareness.

The EPG team has extensive hands-on experience with synchrophasor standards, networks, system architecture, deployments and performance analysis through work at EPG for leading ISO's and utilities including PJM, NYISO, ERCOT, CAISO, MISO, BPA, TVA, SCE, AEP, LADWP, SRP, Duke, Dominion, NYPA and other companies.
