openECA Project Overview - November 8, 2017

3OE-778

FOA 970

To develop an open source platform

that accelerates the production use and

on-going development of both real-time

and off-line synchrophasor-based

analytics

openECA Value to Research Community

Allows the research community to focus on development of new techniques and tools and not on learning how to build information interfaces

Removes barriers to installation of newly developed research tools in production software environments

openECA Value to the Industry

Lowers cost of deploymentSimplified end-to-end configuration and change managementImproved availability of phasor data with greater visibility of phasor data qualityScalable solution to support phasor data infrastructure of any sizeComplements existing phasor data architecture and supports integration with other data sources such as SCADA

The Project Tests the Platform with Analytics

Real-Time Analytics Oscillation Detection Monitor (ODM) Oscillation Mode Meter (OMM) Topology Estimation

Control Regional Volt-Ampere-Reactive (VAR) Control Local VAR Control PMU Synchroscope

Off-Line Analytics Dynamic PMU Transducer Calibration (Automated, Periodic Use Case) Line Parameter Estimation (Ad-Hoc Use Case)

Synchronous Machine Parameter Estimation (Research Use Case)

Acceleration Trend Relay (ATR) Improvement (Research Use Case)

Plus: Linear State Estimation

Server API (targets .NET) Authorizes client data source connectivity Provisions time-series data and metadata

Client API (targets multiple platforms) Manages server connectivity Executes data filtering, organization, aggregation and time-alignment

functionality over user defined time-intervals

Data Modeling Manager Tool Defines data filtering, organization and aggregation Trends incoming data sources


Common Analytics Interface (CAI) Summary

14OE-778

FOA 970

Organizes data into logical groupsCreates data structures that directly map to time-aligned measurement valuesProvides a visual representation of these user defined data structuresDisplays source data as simple trends

CAI – Data Modeling Manager Tool


15OE-778

Security and authentication services

Time-series data transport with support for multiple data types

Metadata distribution and synchronization services

Management of data structure definitions and associated point mappings

RDBMS connectivity, as requiredIncludes support for SQL Server, Oracle, MySQL, PostgreSQL and SQLite

Logging services
