1. Numerical Simulations of Resonant Tunnelling Diodes
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : In this thesis, four different numerical techniques are implemented for the purpose of simulating resonant tunnelling diodes (RTDs). The chosen methods were: piecewise constant transfer matrix (TMM-C), piecewise linear transfer matrix (TMM-L), quantum transmitting boundary method (QTBM), and the Crank-Nicolson method (CN). LÄS MER
2. Development of a Real-Time Simulation Model in RSCAD of a STATCOM and its Control System
Master-uppsats, Uppsala universitet/ElektricitetsläraSammanfattning : The development of interconnected power systems together with an increasing number of renewable non-synchronous power sources, create major challenges for the power system to meet the voltage stability and power quality requirements. One way to increase the voltage stability in a sustainable way is to locally implement a STATCOM. LÄS MER
3. Cross-Country Faults in Resonant-Earthed Networks
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Reliability requirements for power systems have been constantly increasing, as customers of electric power desire high power availability. In order to improve continuity of supply in medium voltage (MV) networks, utilities in many countries in Europe, North/South America and Oceania use resonant earthing and allow the operation of the network during a single phasetoearth fault for periods from several seconds up to several hours, since the earthfault current at the fault point in such systems is considerably reduced and is unlikely to damage equipment or create hazardous voltages for people or livestock.

4. RTDS modelling of battery energy storage system
Uppsats för yrkesexamina på avancerad nivå, ElektricitetsläraSammanfattning : This thesis describes the development of a simplified model of a battery energy storage. The battery energy storage is part of the ABB energy storage system DynaPeaQ®. The model has been built to be run in RTDS, a real time digital simulator. Batteries can be represented by equivalent electric circuits, built up of e. LÄS MER
