  4. 12. Route Adaptation of Charge strategies for Hybrid Vehicles

    Author : Jan Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver model; modelling; control strategies; road model route adaptation; powertrain; charge strategies; simulation; hybrid vehicle; vehicle propulsion;

    Abstract : For vehicles with energy storage devices, here referred to as hybrid vehicles, the control of the system is of great importance. The hardware system can not be judged without its control. This thesis describes a method for determining the potential of an arbitrary vehicle propulsion system for a prescribed driving mission.

  5. 13. The Analysis of Thermal Power Stations and their Interaction with the Power System using Simulator Test Methods

    Author : Jan Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal power station; network simulator; frequency control; island operation; turbine model;

    Abstract : This thesis describes a new method of testing power stations with regard to their frequency control behaviour and analyses results obtained using this new method. The test concept is based on that the power station unit to be tested remains synchronized onto its normal strong network, whereas the frequency control behaviour is set up to be that of the conditions if the unit was working on a much smaller network, using a computer based simulator system and feeding simulated control signals to the input of the units frequency control system.

  7. 15. A GIS-based landscape analysis of dissolved organic carbon in boreal headwater streams

    Author : Jan-Olov Andersson; Lars Nyberg; Hjalmar Laudon; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; boreal forests; wetlands; vegetation types; headwater streams; catchment hydrology; streamwater chemistry; DOC; GIS; terrain analysis; DEM; slope; wetness index; TWI; Freshwater ecology; Limnisk ekologi; Biology; Biologi;

    Abstract : In boreal catchments, stream water chemistry is influenced and controlled by several landscape factors. The influence of spatially distributed variables is in turn dependent on the hydrological scale. READ MORE
