1. Dynamic Modeling of Target's Cooling Systems
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : The thermal energy generated from the spallation process in the ESS facility must be cooled by cooling systems in order to ensure safe operation of the facility. It is of interest to understand what operating conditions of the cooling systems will ensure this safety for both stationary conditions and transient events. READ MORE

3. Modelling of a Generic Aircraft Environmental Control System in Modelica
University essay from Linköpings universitet/Fluida och mekatroniska systemAbstract : This thesis documents the modelling of generic Environmental Control System(ECS) of an aircraft in Modelica by utilizing components from free version of theTTECCS (Technical Thermodynamic Environmental Control and Cooling Systems) library. In doing so, components used for developing ECS from the TTECCS library are mathematically verified with theoretical formula in MATLAB. READ MORE

5. Improved control strategies for primary frequency control in Swedish combined heat and power plants
University essay from Lunds universitet/Institutionen för reglerteknikAbstract : A model of the Swedish power plant Mälardalen Energi, developed by Solvina AB was simulated in Dymola with different types of control strategies in order to evaluate if they could improve the operational flexibility of the plant and, thus, its ability to deliver frequency control to the Swedish power grid. Several different control strategies and process modifications were tested and compared to previous simulations done by Solvina. READ MORE
