RomaniaSC Electrocentrale Bucuresti SASystem DetailsControl systems: CENTUM CS 3000/UOI, ProSafe-RSNumber of I/O points:6,900 (1,300 hard wired, 3,600 via Profibus, 2,000 via other bus protocols)System configuration:4 UOI viewers, 2 engineering stations, 2 UOI servers, 1 Exaquantum server, 1 SOE server, 1 IEC server, 4 50” plasma screens, 8 FCS, 1 safety control station (SCS)About VA Tech Hydro / Combined Cycle Division (Siemens AG Österreich)VA Tech Hydro GmbH & Co. is a global concern that belongs to the VA Technologie AG (VA Tech) group of companies. VA Tech Hydro is one of the world’s largest suppliers of electromechanical equipment and services for the hydroelectric power generation market ("Water to Wire"), and holds a leading position in the growing power plant refurbishment sector. It has approximately 3,000 employees. In 2006, VA Tech Hydro’s Combined Cycle Division was acquired by Siemens AG Österreich, which is located in Vienna, Austria.02Features of Yokogawa Solutions for the Customer1. Single Operator InterfaceThe CENTUM CS 3000/UOI provides a single operator interface for the operation, management, and maintenance of the plant’s turbines, HRSG, balance of plant (BOP) facilities, and electrical systems.Yokogawa’s unified operator interface (UOI) makes this possible. It was developed by Yokogawa to provide a common control platform for the CENTUM DCS and the GE Mark VI gas turbine control system. All data from the GE Mark VI turbine control system, Siemens Simatic steam turbine control system, and other plant systems can be accessed from the CENTUM CS 3000/UOI. No gateway is required. The București Vest CCHP is operated and monitored from four operator stations that are located in the central control room and provide access to more than 90 process graphics. Each of these stations has four monitors that can display four separate graphics. In addition, there are four 50” operator displays. The turbine graphics and other system graphics are shown below. With these graphics at the CENTUM CS 3000/UOI stations, operators can monitor and control all the plant’s different systems with the same look and feel. 2. Automatic Plant Start-up and Shutdown For the new CCHP, Yokogawa configured block sequences for automatic plant start-up and shutdown.The heating plant units that supply up to 190 MW of thermal energy to Bucharest’s district heating network were also automated to ensure a high degree of flexibility in responding to fluctuations in demand.The power plant can be operated in an accentuated electrical mode or in an accentuated thermal mode that requires the calculation of complex mathematical equations. This computation can be handled by the DCS field control station (FCS) and does not need to be outsourced via OPC or other means.3. Advanced Alarm Management Alarm management at this power plant is done with Yokogawa’s Consolidated Alarm List software. This manages both DCS and turbine controller alarms as well as alarms from subsidiary controllers and safety systems, using the sequence of events (SOE) signals to timestamp these events with millisecond accuracy. ata Highway for Mark VIControl Bus (VnetIP)CENTUM CS3000 FCS(s)(for HRSG)CENTUM CS3000 FCS(s)(for BOP)UOI Server(s)(CIMPLICITYServer)CENTUM CS3000 Builder PCSiemens S7(for Steam Turbine)Mark VI(for Gas Turbine)Configuration PCUnified Operator Interface (UOI)Unified Operator Interface (UOI)UOIUOIUOIUOIUOIEthernetData/Message fromHRSG/BOP ProjectData/Message fromTurbine ProjectCIMPLICITY ServersTurbine Control by General Electric CompanyTurbine Control by General Electric CompanyHRSG/BOP and Safety Controlby YokogawaHRSG/BOP and Safety Controlby YokogawaUOI viewers(CIMPLICITY)ProSafeRSSCS(s)(for safety)ataHighwayfoffrMarkkVISiemensS7(foffrSteamTurbineee))))MarkVIGasTurbinnnee))))tionPCCIMPLICITYTTServersUnit Data Highway for Mark VIControl Bus (VnetIP)CENTUM CS3000 FCS(s)(for HRSG)CENTUM CS3000 FCS(s)(for BOP)UOI Server(s)(CIMPLICITYServer)CENTUM CS3000 Builder PCSiemens S7(for Steam Turbine)Mark VI(for Gas Turbine)Configuration PCUnified Operator Interface (UOI)UnifiedOperatorInterfaffce(UOI)Unified Operator Interface (UOI)UOIUOIUOIUOIUOIUOIUOIUOIUOIUOIEthernetData/Message fromHRSG/BOP ProjectData/Message fromTurbine ProjectData/Message fromHRSG/BOP ProjectData/Message fromTurbine ProjectCIMPLICITY ServersTurbine Control by General Electric CompanyTurbineControlbyGeneralElectricCompanyTTTuuuuurrrrrbbbbbiiinnnnneeeeeCCCooooonnnnntttttrrrrrooooolllbbbyyyyyGGGeeeeennnnneeeeerrrrraaaaalllEEEllleeeeeccccctttttrrrrriiicccccCCCooooommmmmpppppaaaaannnnnyyyyyTurbine Control by General Electric CompanyHRSG/BOP and Safety Controlby YokogawaHRSG/BOPandSafeftyControlbyYokogawaHHHRRRRRSSSSSGGGGG/////BBBBBOOOOOPPPPPaaannnnndddddSSSaaaaafffffeeffffeeettffeetttyyyyyCCCooooonnnnntttttrrrrrooooolllbbbyyyyyYYYYYoooookkkkkooooogggggaaaaawwwwwaaaaaHRSG/BOP and Safety Controlby YokogawaUOI viewers(CIMPLICITY)ProSafeRSSCS(s)(for safety)(Electrical plant overview)(Condensate system)(Gas turbine startup)(Steam turbine by-pass control)
