Innovative tuning approach will allow comprehensive off-line low-risk digital control system checkout prior to commissioning
FOXBORO, MASSACHUSETTS, USA - December 13, 2005 - Invensys Process Systems has been selected by Omaha Public Power District (OPPD) for advanced SimSci-Esscor (www.simsci-esscor.com) virtual stimulation technology using FSIM Plus software to fully verify and tune the OPPD Fort Calhoun Nuclear Power Station's upgraded Foxboro (www.foxboro.com) digital automation system. The contract also includes software and engineering services to bridge the controls simulation to Fort Calhoun's existing plant simulator.
Fort Calhoun Station, located eight miles north of Omaha, Nebraska, is a pressurized light water reactor facility with generating capacity of 492 megawatts. Operating safely since it was built in 1973, Fort Calhoun Station has received an extension of its operating license from the Nuclear Regulatory Commission (NRC). OPPD is in the process of upgrading the facility, including new steam generators, a new reactor vessel head and a new pressurizer to allow it to continue operating safely and efficiently until 2033.
The FSIM Plus simulator will be used to exactly model the upgraded I/A Series digital control systems at Fort Calhoun Station. Virtual stimulation technology uses the underlying digital controller source code, which is ported to a low-cost computer platform and combined with simulation functionality. This virtual controller communicates with operator workstations, exactly duplicating the control room experience in an off-line, low risk manner.
As an exact representation of the plant controls, the FSIM Plus virtual stimulation allows for the control algorithms to be tested in the simulator before installing the controls in the plant. This Invensys "test before install" strategy also eliminates subsequent forced outages caused by live control configuration error resolution, and can result in enormous savings to the plant.
By using SimSci-Esscor software bridge capabilities, the Invensys simulation solution allows the controls configuration and graphics files from the plant to be downloaded onto the Fort Calhoun Station's existing plant simulator as-is. It uses the same tools and operator interface as the plant, without imprecise translations, conversions, or other emulation. It will also allow Fort Calhoun Station operators to continuously maintain their plant simulator as controls are upgraded.
The bridge technology helps address such challenges as operator new-technology skills training, keeping existing emulators current with control system advances, and streamlining verification and tuning for the new controls.
The OPPD Fort Calhoun Station contract for simulation solutions follows an earlier control system modernization contract with Invensys for the latest I/A Series automation technology. The control system modernization will also use the latest Foxboro high availability, high speed mesh backbone technology for the Fort Calhoun plant data network.
