CAPE CANAVERAL AIR FORCE STATION SUPERVISORY CONTROL SYSTEM

Project Description -

Provided project planning, feasibility studies, and system design for a replacement supervisory control and data acquisition (SCADA) system which controls the high voltage distribution system and standby power plants at the Cape Canaveral Air Force Station. Estimated cost for a turnkey control system is $700,000. Contracted services included control system design, specification of control equipment and software, RTU/PLC software planning and design, communications system design, user training, and graphical control and alarm screen design and planning. New supervisory control system will deploy programmable logic controllers (PLC) to serve the remote terminal unit (RTU) functions, electronic multifunction metering system to provide power measurement data, and PC-based graphical user stations. Next phase of USAF project procures control system equipment, performs software programming, testing, installation, and startup. Refer to Figure 5 for the Cape Canaveral supervisory control system diagram.

Benefits/Value Added -

The control system design incorporates the use of GE Fanuc PLCs which are deployed at existing Power Plants currently in operation at Cape Canaveral. This measure will ensure a reliable, trouble-free interface between the new control system and the existing Power Plant controls. In addition, life cycle operating and maintenance costs for the new GE PLC-based system will be minimized as the Cape Canaveral personnel are already familiar and trained on using GE PLCs. The new control system design also eliminates the high cost and high maintenance associated with analog power tranducers by replacing these transducers with new electronic meters. One electronic power meter provide the same power measurement functionality as 16 power transducers at a fraction of the cost.
