1. Influence of the semi-conducting screens on the wave propagation characteristics of medium voltage extruded cables
Sammanfattning : .... LÄS MER
2. Topographical Impact on Space Charge Injection, Accumulation and Breakdown in Polymeric HVDC Cable Interfaces
Sammanfattning : Extruded HVDC cable systems feature a variety of interface types, for which physio-chemical properties will depend on the type of application. Such applications can be joints, terminations or the cable itself, all introducing different material combinations and manufacturing methods. LÄS MER
3. Analysis of Fatigue Characteristics in Mooring Lines and Low Voltage Cables for Wave Energy Converters
Sammanfattning : To reduce both carbon emission and fossil fuel consumption, there is a pressing need for the exploitation of renewable sources of energy such as biomass, hydropower, solar power, waves, and wind. This thesis addresses the application of wave energy, which has a large potential to contribute to the world’s renewable emission-free energy supply. LÄS MER
4. Nyquist Stability Analysis of a VSC-HVDC System with a Distributed Parameter DC-cable Model
Sammanfattning : Voltage source converter based high voltage direct current (VSC-HVDC) transmission systems have now been in operation since 1997 as it is a reliable and flexible method of power transmission. This thesis focuses on small signal dynamics of such systems, emphasizing stability properties. LÄS MER
5. Mechanical models for electrical cables
Sammanfattning : A theoretical and experimental study of mechanical properties of electrical cables with multi order helical structure has been performed. Relations between applied deformations and local strains in the first order helical structure have been developed. LÄS MER
