Online validation of measurements
Calculated measurements for areas where there are no installed instruments
Helps justify uncertainty of measurements. Operation closer to specifications
Online optimization tools work with more accurate information
Reduced frequency of sensor calibration. Only faulty sensors are calibrated
EDF Torness: Summary
7
• History of Simulator– Various systems were upgraded by GSE
previously Turbine Supervisory and Electrical Systems
– Was built in 1989 by Marconi– EDF extended the operating life of the plant
by 7 years to 2030 and decided to replace and upgrade the simulator to overcome limitations in computing systems, plant models and control systems
• Objective– Modernize existing simulator built in 1980s– Leverage similarity with Heysham 2 Plant
EDF Torness: Scope

• Simulate ALSTOM turbine control system
• Simulate fueling machine system
• Provide 5 simulator platforms; Unit 1, Unit 2, Classroom, De-briefing , and Development
• Provide integrated Unit 1 and Unit 2 simulators
• Provide touch screen softpanels
EDF Torness: Technology• JADE suite of simulation tools
• SimExec
