Mission: provide a redundant EMS with emergency backup geographic separation. Install new RTU technology into the existing substation RTU cabinets as a result of no available substation expansion. Provide an information platform to support the functions of Energy Accounting and Scheduling and Portfolio Management System, Load Monitoring and Trouble Call Analysis.

Business Issue: In March 1999, ACS was contracted to deliver a turnkey Master EMS replacement system. Due to corporate requirements and to mitigate Y2K preventative action the scheduled delivery of the system, system startup and turn key RTU installation must take place within four months.

Project description

Advanced Control Systems was awarded, and successfully delivered with an accelerated delivery schedule, a turnkey SCADA/EMS Master system. The turnkey contract included the installation, wiring, and connection of the substation RTUs and master equipment.

The Primary SCADA Master computer is located in the main control center building. The backup SCADA Master is located in a back-up control center. On the failure of the Primary master, the secondary system automatically assumes the primary role and operations continue without noticeable affect on system functionality.

To meet the rapidly changing business drivers evolving under the new requirements of deregulation, and an increasing effort to improve customer service, the City of Pasadena contracted with ACS to provide a comprehensive, flexible and modular platform to support the new business subsystems. These subsystems include the new functions of Energy Accounting and Scheduling and Portfolio Management System, Load Monitoring and Trouble Call Analysis.

In addition, a corporate Enterprise RDBMS server provides corporate users access to the archived real-time information. The new system also has access through a firewall server to the corporate network as well as the Internet. Operators and Users have access, allowing the proper security permissions, to information and displays from the system on their native desktop computers, without the requirement for specialized computer equipment. The system supports access from UNIX, Microsoft or Windows 95/98 operating systems. Enterprise users access the system from an enterprise data server.

Due to limited expansion in the substations, and an effort to minimize installation costs it was decided to customize the RTUs to fit existing cabinets and utilizing existing RTU wiring. The existing RTU cabinets were measured for size and configuration such that custom panels could be mounted with the NTU 7510 components mounted in such a manner as to interface to the existing wiring terminations. ACS was responsible for the decommissioning of the existing RTUs and the installation of the new RTU components.

ACS was also responsible for the database and display building which was supplied for the base SCADA/EMS and integrated into the system prior to FAT.

ACS also provided an interface to the DCI PMU. ACS developed the application to interface between the DCI Sentry Master Receiving Station and the real time database reporting events within the SCADA/EMS as normal real-time monitored data. The Sentry units are mounted in customer locations reporting power quality and outage information automatically via a dial-in phone connection. The data is logged, alarmed and displayed on the SCADA/EMS/DMS one-line diagrams as any real-time data. The outage locations are prominently displayed on an overview system map.

Switch Order Management and Command Interpreter Scripts are used to support the City's Volt/VAR control/Cap Bank control requirements.

ACS delivered an Outage Management System with an AM/FM system. The AM/FM system provides the ability to interface directly to the facilities information through the SCADA/EMS/DMS dispatchers one-line diagrams. Facility access includes equipment specifications, maintenance information, and exchange of network connectivity information. The integrated interface includes the ability to automatically maintain the database linkages between the two systems as files are imported.
