The specific facilities and equipment covered at the first control level are as follows: • Boiler main burners• Electrostatic precipitator (ESP) of boiler• Steam turbine and generator• Cooling system• Water system• Secondary boiler burners• Fuel (wood) area• Shipped fuel scaling station• Electrical system 10 kV protection• Electrical system monitoring• Electrical system switch-over automation• 120 kV electrical systemCENTUM VP system architectureYokogawa was responsible for the engineering, installation, and commissioning of the CENTUM VP DCS, and also provided training to the plant’s operators and system engineers.Two human interface stations (HISs) with two monitors each allow operators in the central control room to monitor and control operations throughout the plant. In real time, graphic windows display measurement, sequence, trend, and other information that give operators a real-time view of conditions throughout the plant. The system includes a combined engineering/operator station in the central control room.Facilities and equipment at the first level are all controlled in full synchronization with the Yokogawa DCS. Together with turbomachinery train control, all processes from plant startup to plant shutdown are executed smoothly. With the exception of startups and intentional shutdowns, operator interventions are not required. Thanks to Yokogawa’s leading edge DCS, all the processes at this advanced biomass power plant have been automated. Operator error has thus been eliminated in all critical processes, and high reliability and availability are ensured.36Customer Satisfaction“The challenging control strategy was managed perfectly. Furthermore, the reliability of the Yokogawa DCS has exceeded our expectations.” - Burai Bertalan, a member of the start-up team and head of Veolia’s Electrical and Instrumentation Department Veolia Biomass Power / Hungary
