1. On the Analysis of DC Network Dynamics of VSC-based HVDC Systems
Sammanfattning : In this thesis, the dc network dynamics of VSC-HVDC systems is investigated through eigenvalue and frequency domain analysis. The eigenvalue analysis has been used to identify the factors that have an impact on the system stability. LÄS MER
2. On Power-system Benefits, Main-circuit Design, and Control of StatComs with Energy Storage
Sammanfattning : Static synchronous compensation (StatCom) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, StatComs are employed for reactive power support only. LÄS MER
3. A biophysical study of nucleic acid interactions with analogues and drugs
Sammanfattning : work presented in this thesis concerns studies on the physicochemical nature of interactions between nucleic acids and small ligands. The outcome of such studies can yield insights at a molecular level into the physiological mechanisms of action of biologically active nucleic-acid binding molecules. LÄS MER
4. Power Control Systems for PM Synchronous Flywheel Alternators
Sammanfattning : Flywheel systems are attractive in hybrid and electric vehicles, being able to handle the large power when accelerating and for regenerative braking. The combination of a flywheel device with a battery source has several advantages, such as higher peak power capacity, higher energy density and a decrease of the number of charging/discharging cycles in the battery.
