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

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

    Sammanfattning : 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.

  5. 4. Smoothed Particle Hydrodynamic of Hydraulic Jumps in Spillways

    Författare :Patrick Jonsson; Peter Stansby; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : This thesis focus on the complex natural phenomena of hydraulic jumps using the numerical method Smoothed Particle Hydrodynamics (SPH). A hydraulic jump is highly turbulent and associated with turbulent energy dissipation, air entrainment, surface waves and spray and strong dissipative processes. LÄS MER

  7. 5. Using Architectural Principles to make the IT-Strategy come true : focusing on the electric power ndustry

    Författare :Åsa Lindström; Torsten Cegrell; Bernt Ericsson; KTH; []
