Dynamic simulation helps us to understand the system dynamic properties. Our simulation models are based on first principals. We use existing simulators as ASSETT and D-SPICE, or we develop and implement our own in Matlab, Extend or SENIT.
We use dynamic simulation to:
- Verify control philosophy and control structures
- Perform operability analysis
- Perform safety analysis
- Optimise the process
We use data analysis to:
- Estimate parameters that cannot be measured (e.g. pressure in offshore pipelines)
- Generate prognoses (e.g. for number of errors occurring during the next period)
- Develop black-box mathematical models (e.g. in testing of control system)
Main fields of competence:
- Modelling of dynamic systems based on first principals
- Dynamic system analysis
- Data analysis
- Black-box modelling (Neural networks, AR models etc.)
- Optimisation
- Programming
- Commercial simulators
Applications:
- Verification of control system
- Verification of safety system
- Operator training
- Fault detection
- Operability analysis
- Duty monitoring
- Decision support
On-going projects (2005/2006):
- Use of Snøhvit dynamic simulator D-SPICE in compressor analysis
- Development of a dynamic simulator for a small scale hydrogen production unit (www.hydrofueler.org)
