2 Transmission Utility of Dominican Republic

3 Transmission Utility of Dominican Republic State-owned Utility km lines of 138kv 26 Transmission substations Transmission lines radiate from Santo Domingo to the whole country

4 Project Motivation 26 Substations with aging technology and intricate wiring Unreliable SCADA data and controls Constant troubleshooting No remote access to Protection & Control devices 9 Substations not connected to SCADA Master Operator dependent stations No local HMI for local monitoring and operation

5 Project Goals Total IED management strategy Remote Engineering Access to IEDs Automated Fault File Collection and Fault Location Configuration Management Document Management Implementation of substation local HMI for local operation and monitoring

6 Transmission Utility Requirements To submit Fault Files within 1, 2, and 12 hours of an event Upload Fault Files to the WEB server 9 Months of historic information Case Study

7 The Challenge Telecommunication infrastructure Serial communication Fault File transfer over serial File transfer vs. SCADA real time data IP based communication Terminal servers Cyber Security Multi-vendor Devices Every vendor implements it in a different way Automatic Fault File Submission Fault File Management Fault Files & Documents Management

11 Automatic Fault File Collection Automated Fault File collection from devices Automated file transfer from substation to corporate Notification of new Fault File Initiation of Work flow process on arrival of new Fault Files Pre-installed analysis applications

12 Fault File Archive Collected Fault Files are archived to allow easy user access Archives provide simple searches and filters to quickly and easily view Fault Files of interest.

13 Users subscribe to Fault File Alerts for a specific device, or Fault Files coming from a specific substation. Notification and Workflows Once new Fault File arrives an notification is sent to subscribed users

14 Store, organize, and locate IED documents IED Document Management Ensure the consistency of documents Help protect documents from unauthorized access or use Ensure consistent business processes (workflows) for how documents are handled

15 Per-User / Per-Device Authentication Integration Hierarchy Filtering Filtered IED List Per-Device Type Application Management Automated Application Launching Command Trapping Filters Secure Remote Engineering Access

16 Open XDA extensibledisturbance Analytics What is Open XDA: A back-office automated service to automatically process and analyze event and trending data from transmission and distribution metering DFRs and PQ metering It includes a parser for COMTRADE and PQDIF formatted records Demonstrations have been conducted using.eve files. Can be used as a data integration layer Can facilitate the development of automated analytic systems. Has been deployed in a number of major US utilities to perform automated fault distance calculations based on disturbance waveform data combined with line parameters.

17 Open XDA extensibledisturbance Analytics

18 Open XDA extensibledisturbance Analytics Integration: The document management system was integrated with OpenXDA. Fault files are automatically retrieved from field IEDs, then sent to OpenXDA for automated analysis. OpenXDA produces automated fault recognition, type determination, and distance to fault calculations. Notifications are sent to users by with the analysis result.

19 Open XDA extensibledisturbance Analytics Integration: Base on system architecture, file collection can be performed in a centralized or distributed manner. In a centralized architecture, fault files are collected directly from end devices by the corporate system. In a distributed architecture, the fault files are collected locally at each substation and then sent to the corporate system for analysis.

20 Open XDA extensibledisturbance Analytics Deployment: Fault files collected from devices trigger an automatic analysis of the files. OpenXDA produces automated fault recognition, type determination, and distance to fault calculations to be included in notifications, s, or an event database. Systems built on the OpenXDA platform can produce analytic results as quickly as files can be retrieved from the remote devices.
