2. Analysis of factory test data of on-load tap-changers for power transformers
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknikSammanfattning : On-load tap-changers (OLTC) are devices in the power grid that keeps the voltage level constant for consumers, regardless of the power demand. Hitachi ABB Power Grids, producer of the OLTC family named VUC, guarantees 30 years of lifetime. Such a pledge requires high standard devices. LÄS MER
3. Dielectrics calculation of on-load tap-changer VUCL
M1-uppsats, KTH/Hållbar produktionsutveckling (ML)Sammanfattning : This is a bachelor's thesis in Mechanical engineering. The main topic of the thesis is the electrical calculation of the tap changer's shield. Although there are many kinds of tap-changers, this study focuses on VUCL models. The theoretical background of the thesis is that the new shield is suitable and useable in all VUCL models. LÄS MER
4. Distribution On Load Tap Changer Control Using IEC61850 Client/Server Architecture
Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)Sammanfattning : Distributed generation is transforming the power system grid to decentralized system where separate units like wind power generators or solar panel shall coexist and operate in tandem in order to supplement each other and make one extensive system as a whole so called smart grid. It is utmost important to have a control ability over such units not only on a field level but on a system level as well. LÄS MER
5. Evolution of the LV Network
Master-uppsats, KTH/Elektriska energisystemSammanfattning : Providing reliable electricity to everyone is a very important matter nowadays. Both thetransmission system operator and the distribution system operator are acting on the grid inorder to insure it. The latter sometimes has to deal with problems regarding the voltage,especially in rural areas. LÄS MER
