Tandum Compound Reheat Steam Turbine rated @ 210 MWPROJECT: DCS Upgrade ProjectAn independent power producer (IPP) owned a significant portion of the west coast generation assests including a 210 MW unit consisting of a natural gas fired Riley Stoker boiler and a Westinghouse tandem compound turbine/generator. This client needed to install a Selective Catalytic Reduction (SCR) system to meet recent air emission standards but their existing Bailey pneumatic boiler combustion control system with a partial Westinghouse WDPF DCS temperature control system was obsolete and inadequate for this type of a control system upgrade. The IPP's choice was to perform a full unit control system upgrade. The IPP's in-house control system expertise was talented and enabled them to bid a full control system upgrade specification with the successful supplier being ABB Inc. with their Symphony control system. A project of this magnitude would have overloaded the IPP's single control system expert to manage so the IPP contracted for management services as a formal Project Manager. A specific criterion requested by the IPP was that the Project Manager have an extensive background in process and control systems. RESULTS• Coordinated, managed, and directly participated in the major Distributed Control System (DCS) upgrade Factory Acceptance Test (FAT) for a complete boiler, turbine/generator, BMS, and balance of plant software controls. • Utilized an ABB supplied simulation software from the FAT to fully integrate the whole DCS upgrade into a simulator prior to actual installation. Completed full unit testing of boiler, turbine/generator, BMS, and balance of plant controls. |
