1. District Cooling – Towards Improved Substation Performance
Sammanfattning : The global cooling demand in buildings is rapidly increasing and to supply this demand, district cooling is one solution. However, many district cooling systems suffer from low delta-Ts (receiving low return temperatures from the buildings connected to the system). LÄS MER
2. Ocean Wave Energy : Underwater Substation System for Wave Energy Converters
Sammanfattning : This thesis deals with a system for operation of directly driven offshore wave energy converters. The work that has been carried out includes laboratory testing of a permanent magnet linear generator, wave energy converter mechanical design and offshore testing, and finally design, implementation, and offshore testing of an underwater collector substation.

3. Thermal Study of a Submerged Substation for Wave Power
Sammanfattning : At the Division of Electricity of Uppsala University, a wave power concept is being developed.It relies on wave energy converters, one buoy and one linear generator placed on the seabed, connected together to a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. LÄS MER
4. Distributed Signal Processing in Digital Substations : Integrating High Sampling Rate Measurements at the Process-Level
Sammanfattning : Future power systems will be dominated by power electronic (PE) converter connected generation. This trend is primarily driven by the increasing penetration of wind power as well as the increasing integration of photovoltaic (PV) based generation. LÄS MER
5. Fjärrvärmekunders värme- och effektbehov: analys baserad på mätresultat från femtio byggnader
Sammanfattning : An extensive measuring project has been carried out by Gothenburg Energy which operates the Gothenburg district heating system. Over a period of 18 months, heat loads, water flows, temperatures, etc., were measured at 15 minute intervals at 50 substations. LÄS MER
