EMS Migration • Migration Philosophy
Migration Philosophy • In 1995, PEPCO Adopted a Long-Term EMS Migration Philosophy to Keep the EMS “Ever-green”.
Migration Philosophy • Migration Rationale: • Keep the system technologically current to meet the terms of the financial lease • To protect the investment in the operational procedures, EMS software, system design, & database. • To avoid obsolescence of hardware
Migration Philosophy • Migration Rationale (cont.): • To support increased performance and capacity requirements • To allow for the addition and enhancement of system functions as business requirements change • Enhance the EMS to accommodate the implementation of large-scale Distribution Automation and Substation Automation projects
Migration Philosophy • Migration Rationale (cont.) • And, to avoid the extreme and expensive effort of another EMS “forklift” replacement, including: • Procurement costs • System Testing • Cutover • Software Quality Control • Staff time commitment
EMS Migration • Overview of the PEPCO EMS
Overview of the Original PEPCO EMS • EMS is “Consolidated Control System” • Designed to support Transmission, Distribution, and Generation Operations • (Generation sold December 2000)
Overview of the Original PEPCO EMS • Interfaces with other critical PEPCO and external systems including: • New Outage Management System • Corporate Systems • PJM
Overview of the Original PEPCO EMS • Procured from ABB Network Management (formerly NMTI) • Delivered in 1993 • Initially commissioned in 1994
Overview of the Original PEPCO EMS • Full featured EMS including: • SCADA • Graphical User Interface (not workstation based Full Graphics) • Distributed System w/ Proprietary Hardware Front-ends • Full Advanced Applications Suite • Real-time and Study • PEPCO Specific Applications
Overview of the Original PEPCO EMS • Dispatcher Consoles • Transmission Dispatchers • Load Dispatchers • Transmission Shift Supervisors • Distribution Shift Supervisors • System Support Consoles • Development and Testing Facility • Dispatcher Training Simulator
EMS Migration • PEPCO Migration Phases
Migration Phases • PEPCO established a multi-year migration program: • To fully migrate the EMS every seven years. • PEPCO’s management committed to to fund the effort to avoid the high costs of another procurement.
Migration Phases • Migration Phase I – 1995 – 1996 • Open Systems Platform Enhancements including: • Introduction of Dec Alpha Hardware Platform • Operating System Upgrades • VAX VMX to UNIX • Intel RMX to UNIX
Migration Phases • Migration Phase I (cont.) • Conversion of Code to C • (from less common/difficult languages – PLM, Assembly) • FORTRAN not converted
Migration Phases • Migration Phase II – 1997-1998 • ICCP for standards-based communications with: • PJM • PEPCO to BGE (planned merger) • Ranger Data Acquisition Server • Compaq Alpha hardware and Unix operating system • Bow Software Protocol Emulations
Migration Phases • Migration Phase II – (cont.) • Addition of PI Historian Data Repositories • Upgraded DTS • Increased Database Sizing • Via System Master Parameters
Migration Phases • Migration Phase III – 1999 – 2000 • Workstation Based Graphical User Interface • ODBC Interface Into EMS • NT Based Historian • Study Mode State Estimator – Uses Historian Data for Studies • DNP Protocol
Migration Phases • Migration Phase III (cont.) • Event Storage and Retrieval • Updated Software Tools to Improve Maintenance and Support Environment
Migration Phases • Migration Phase IV – 2001-2002 • (currently in progress) • Increase DB Sizing (1.5 x current) • Naming size increases • DNP Protocol Converter (Rockwell 5020 to DNP) • Transfer Existing RTU to RDAS • Graphical Data Engineering Tool • CIM Based
Migration Phases • Migration Phase IV – (cont.) • Facilities and Support Systems • Console Voice Equipment (integrates PEPCO’s radio and telephone requirements) • Upgrade/Life Extension for Critical Power (UPS) and HVAC
Migration Phases • More to Come? • Phase V – Commercial Display Generation Software • Phase VI – Upgrade EMS Application Processors, storage devices, printers, Bow-Tie Equipment, LAN I/F • Phase VII – SCADA System • Phase VIII – Advanced Apps. • These phases are currently under review
EMS Migration • Related EMS Enhancement Efforts
Related EMS Enhancement Efforts • RTU Protocol Conversion for existing RTUs • Outage Management System/EMS Interface – using ICCP • Source Data Management System – to improve data management process • System Security Enhancements
Related EMS Enhancement Efforts • PEPCO Substation Automation Initiatives: • Increased data from smart relays and Substation Automation systems (4 kV, 13 kV, 69 kV, 230 kV substations) • VAR Dispatch – using feeder capacitors.
Related EMS Enhancement Efforts • PEPCO Distribution Automation Initiatives: • Feeder sectionalization using fault detectors and Motor Operated Disconnects • 69 kV MODs • 13 kV MODs • Utilinet Spread Spectrum Radios
EMS Migration • Future Migration Phases
Future Migration Phases • Migration of Advanced Applications to support: • New Business Needs • New ISO Support Requirements • New Corporate Information Needs • Corporate Reorganizations and Industry Restructuring
EMS Migration • Long-Range Plan & Update Process
Long-Range Plan and Update Process • PEPCO is currently reviewing the Long-Range Migration Plan • Looking at current operational and business needs • Investigating current technology • Assessing impacts of restructuring • To properly align the next migration phases with the overall long-term direction
Long-Range Plan and Update Process • Goal is to provide an updated 10 Year Forecast for planning purposes. • Also to more clearly define the near-term needs and associated migration projects.
EMS Migration • Challenges for the Future
Challenges for the Future • Distribution Operations Optimization • Fault detection and automated feeder reconfiguration • Other distribution functions • Additional Expansion of Distribution Functional and Data Requirements • Smart Relays, MODs, etc.
Challenges for the Future • Integration with Corporate Systems • Corporate-wide Data Availability • For Maintenance Monitoring System • Enterprise Application Integration (EAI) Environment
