Control center, City of Anaheim (click on photo to enlarge)
Mission: provide an increasing level of utility services to retail and industrial customers. Provide information to other City of Anaheim departments for the effective coordination of resources and safety.

Business Issue: in 1997, ACS was contracted to deliver a turnkey Master SCADA system replacement system. Anaheim had the following project goal: "Procure and install in one year a control system that allows the utility to take advantage of the advances in substation automation built upon a modern open computing environment that provides information to all city personnel." -Peter Wong, IEEE Winter Power Meeting, Februrary 1999.

In April of 1999, ACS was awarded a follow-on contract to provide a Web Server and the tools to distribute real-time, same-time, and historic data to non-utility department users in both graphical and tabular form with web browser technology.

Key system elements:
  • Site redundant operations

  • Turnkey system delivery including display, database and installation

  • Use of fiber communications system for user interface and data acquisition

  • Delivery of RTUs with DNP 3.0 protocol and IED interfaces

  • Redundant master station hardware

  • Oracle Historical Data Analysis

  • Web Server interface to historic and real-time data

Advanced Control Systems was awarded, and successfully delivered, a turnkey SCADA Master and Substation Automation system. The turnkey contract included the installation, wiring, and connection of the substation and master equipment.

To meet the rapidly changing requirements of deregulation and to meet the needs of its residential and commercial customers, the City of Anaheim contracted with ACS to provide a comprehensive, flexible and modular system. The system must meet the requirements for cost effective system control and integrate to the city's enterprise applications.

The core of the system is based on the City's fiber optic communication network. All elements of the system will use this 100 Mbps fiber backbone to exchange information among the system components. This includes the operator stations, SCADA Master, RDBMS Historical Data Server, and the Substations.

The Substation Automation component of the system uses off the shelf communications technology to connect the 100 Mbps SCADA LAN to the substation equipment. City Employees will have direct access to the substation devices which include: A substation computer providing local control, historical data collection, displays, reports and advanced applications including capacitor bank control; a PLC which will provide intelligent control logic within the substation; Schweitzer Relays for system protection and switching; and an packet radio system for communication with pole top devices, meters and other IEDs located outside of the substation on feeder circuits. The entire system design is modular and expandable to meet the future needs of the utility.

The SCADA Master utilizes the latest open technology to provide a secure and safe operating environment and allow access of information by the entire city enterprise. Operators and Users have access 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 Windows NT and Windows 95 operating systems.

Enterprise users access the system from an enterprise data server. The information from the SCADA Master is transferred to the Enterprise server using the ACS distributed data base technology. This technology ensures immediate and secure transfer of information across the enterprise without impact on system operations. The SCADA Master configuration also uses this distributed technology and the city wide WAN to provide a cost effective solution to the emergency operations and backup control center requirements of the City of Anaheim. The Primary SCADA Master computer is located in the main engineering building. The backup SCADA Master is located approximately 5 miles away in a backup 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.

The main operations control center will include the installation of multiple projection panels for system overviews. Operators will have full control of the projection displays including Zoom with decluttering and Pan. Multiple Displays can also be put on the projection panels. The system will also include a projection system in meeting rooms for use by engineering and operations for training and system analysis.
