WEST Version 3.7.2
Introduction
WEST does not restrict the user to existing models. Due to its use of MSL (Model Specification Language), which is an easy to learn modelling language (just like text processing), it is possible to add/enter own know-how without giving that know-how to a third party.
WEST features
- Experimental design
- Evaluation of design options: When designing a system one can encounter a number of different design options that may comply with the objectives. WEST can provide a time and cost effective testing method to determine the best option. WEST can also be used to evaluate up-scaling the pilot test results on the full-scale plants.
- Process optimisation: When facing an upgrade of a plant, process optimisation may prevent expensive structural works.
- Development of control strategies: Testing different control strategies in real time is in many cases not an option. WEST can provide a testing tool to evaluate these control strategies.
- Minimisation of operational costs
- Evaluation of operating strategies: WEST can be used to evaluate operating strategies through:
- Prediction of dynamic responses of the system to influent variations
- Bottleneck identification
- Plant operation trouble shout
- Decision support (operator)
- Off line simulations: off line simulations may support the operator in the decision making process
- On line simulations (operator in the loop): The data of online sensors is sent directly to WEST, with which the operator can test a number of operating strategies.
- Real time control
- Model based predictive control
- Scenario based predictive control
- Better insight in the processes: The removal of organic matter, nitrogen and phosphorus, is usually accomplished in a single system. WEST is a promising tool to improve the understanding of the interactions between these processes.
