Esper

Compare

  Analyzed about 13 hours ago

Complex Event Processing, or CEP, is technology to process events and discover complex patterns among multiple streams of event data. ESP stands for Event Stream Processing and deals with the task of processing multiple streams of event data with the goal of identifying the meaningful events within ... [More] those streams, and deriving meaningful information from them. The Esper engine has been developed to address the requirements of applications that analyze and react to events. [Less]

openPDC

Compare

Claimed by Grid Protection Alliance (GPA) Analyzed about 8 hours ago

The open source phasor data concentrator is a system that is used to manage, process and respond to dynamic changes in fast moving streaming phasor data. More specifically, the openPDC can process any kind of data that can be described as “time-stamped measured values”. These measured values are ... [More] simply numeric quantities that have been acquired at a source device and are typically called points, signals, events, time-series values or measurements. When a value gets measured, an exact timestamp is taken, typically using a GPS-clock for accuracy – the value, along with its timestamp, is then streamed to the openPDC where it can be “time-aligned” with other incoming measurements so that an action can then be taken on a complete slice of data all measured at the exact same moment in time.

substationSBG

Claimed by Grid Protection Alliance (GPA) Analyzed about 5 hours ago

The substationSBG administered by the Grid Protection Alliance (GPA) couples the high-performance phasor data processing features of the openPDC and the security features of SIEGate into a purpose-built system that is both a substation PDC and a gateway for the secure, reliable communication of ... [More] synchrophasor data from a substation to the control center. It acts as a synchrophasor data gateway in that it can securely and efficiently gather and redistribute high-resolution (e.g., 60 sample-per-second) time-series data from multiple devices and move real-time data in a consolidated stream to a central location, e.g., as upstream openPDC, and also keep a central data repository complete by providing automated data recovery capabilities using its short-term rolling local archive.

openXDA

Compare

Claimed by Grid Protection Alliance (GPA) Analyzed about 8 hours ago

openXDA is an extensible platform for processing event files from disturbance monitoring equipment such as digital fault recorders (DFRs) and power quality meters. In one implementation of openXDA analytics, based on the waveform data in these files and on user-provided transmission line ... [More] parameters, openXDA determines the fault type and calculates the line-distance to the fault. For more information. [Less]
