Acquire Phasor Data

openPDC
Phasor Data Concentrator

openPDCopenPDC on GitHub

The openPDC is a high-performance data concentrator platform for managing streaming synchrophasor and other time-series data in real-time.

The openPDC has been in production use since 2004. It has a proven performance record and it continues to be on a steep improvement curve. Like all GPA products, the openPDC is open source, with no licensing costs so that the system can be easily tested prior to making production implementation commitments.

SIEGate
Secure Information Exchange Gateway for Electric Grid Operations

SIEGateSIEGate on GitHub

SIEGate is a security-centric appliance designed from the ground up to reliably exchange the information necessary to support real-time control room operations. SIEGate can exchange measurement data (ID, time, value, quality), alarm and notification data as well as batch or file-based data. As compared to current utility practices, SIEGate significantly improves security while reducing the administrative burden and cost to exchange grid data among control rooms.

substationSBG
Secure Buffered Gateway

substationSBGsubStationSBG on GitHub

The substationSBG couples the features of the openPDC and SIEGate to form a purpose-built, high-availability data gateway for use in substations. It is both a substation PDC with a local data historian and a phasor gateway to enable the secure, reliable communication of synchrophasor data from the substation to the control center. It has been extensively tested on fan-less substation computers for both 32 and 64 bit processors using either Windows or Linux operating systems.

PDQTracker

PDQTrackerPDQTracker on GitHub

PDQTracker is a high-performance, real-time data processing engine designed to raise alarms, track states, store statistics, and generate reports on both the availability and accuracy of streaming synchrophasor data. PDQ Tracker will work with any vendor’s PDC and synchrophasor data infrastructure; measure and automatically produce periodic reports on phasor data completeness and correctness; alarm and/or create emails in real-time if data quality problems are detected.

Communications Testers

Communications Test ToolsConnection Tester on GitHub
                                                    STTP Connection Tester on Github

Classic Synchrophasor Protocols - The PMU Connection Tester verifies that a data stream from a synchrophasor measurement device can be successfully received and parsed. The PMU connection tester supports multiple phasor data protocols including: IEEE C37.118 (all versions), IEEE 1344, BPA PDCstream, SEL Fast Message, UT-K FNET streaming data protocol, IEC 61850-90-5 and Macrodyne.

Streaming Telemetry Transport Protocol - The STTP Connection Tester is a multi-platform graphical application that can be used to verify connectivity to applications that host an implementation of the Streaming Telemetry Transport Protocol (STTP) data publisher engine. The STTP Connection Tester can be used on Windows, Mac, Linux and Android devices. See Using STTP Connection Tester documentation for more details.

A communications test application is also available for the Gateway Exchange Protocol (GEP) which was a predecessor GPA publish-subscribe streaming-data protocol to STTP. GEP has been part of GPA products since 2012. While STTP is preferred, GEP remains supported as a production protocol by all GPA synchrophasor products.

PH Report

Historian Performance Report - Performance Report on GitHub

The openHistorian Performance Statistics Reporting tool is used to generate data quality for synchrophasor installations and is automatically included with all GPA synchrophasor products. All GPA synchrophasor products are configured to automatically archive performance statistics related to device connections, when enabled this reporting tool will run nightly to produce a data availability and/or data quality report. Note that this tool operates against a v1.0 openHistorian archive.

PH Playback

Performance Historian Export Utility - Performance Historian Playback On GitHub

The openHistorian Playback Utility is used to stream and/or export data from a v1.0 openHistorian archive and is included with GPA synchrophasor products, e.g., the openPDC. The tool is used to export selected signals from a given time-range to a CSV file using a custom format and/or stream the data to a socket for replay purposes.

Azure Cloud IO

Azure Cloud Adapter - Azure Adapter on GitHub

To better support machine learning and other data science studies, Cloud IO is a configurable time-series adapter for sending JSON-formatted communications to cloud-based service providers such as Microsoft Azure. This adapter includes customizable date, data, and meta-data formatting. The adapter has been tested using a real-time stream from about 80 PMUs (at 30 samples-per-second). The adapter is included with all GPA time-series products but is also available as a standalone service using Time-Series Library Cloud IO service.

TSL Adapters

TSL Adapter List

The time-series data processing library (TSL) in the Grid Solutions Framework is a core collection of classes used to manage, process and respond to dynamic changes in fast moving streaming time-series data in real-time. TSL components allow applications to be architected as measurement routing systems. Any application can host the library which will allow the application to become a "measurement router" that can host any of the TSL's pluggable adapters. More information about the time-series adapters that are available as part of the Grid Solutions Framework can be found in the online adapter documentation.

The openPDC, SIEGate, and opehHistorian are examples of projects based on the TSL. To build a time-series application that can use any of these adapters, or other custom adapters built on the TSL, see the Project Alpha GitHub site and some simple steps on building a time-series library project.


See: The TSL Adapter List

No Internet Fix

No Internet Fix Utility - No Internet Fix on GitHub

The No-Internet File Utility tool is used to update GPA products to better operate on a system that does not have access to an Internet connection and is automatically included with all GPA products. GPA products use TLS certificates and executable code signing which will automatically attempt Internet based validation, without an Internet connection these types of operations will timeout and cause slower than normal start times. The No-Internet File Utility tool can be used to bypass specific Internet based validations for GPA tools to increase product load times.

PDCimporter

openPDC Configuration Import Utility - SEL Import Utility On GitHub

The openPDC Configuration Import utility takes SEL 3373 or 3573 PDC configuration files and uses the information to directly import the configuration information it into openPDC. Using this tool over the built-in IEEE C37.118 wizard ensures any extra configuration details that have been configured in the SEL PDC, including proper connection information, get properly captured by the openPDC. This tool is distributed along with the openPDC and openHistorian.

GPA encourages and actively supports developers in making contributions to our open source projects.
We have published coding guidelines to make the process of incorporating your code go smoothly.
