1. Steady State Operation and Control of Power Distribution Systems in the Presence of Distributed Generation
Sammanfattning : In this thesis, the impact of distributed generation (DG) on steady state operation and control of power distribution systems is investigated. Over the last few years, a number of factors have led to an increased interest in DG schemes. DG is gaining more and more attention worldwide as an alternative to large-scale central generating stations. LÄS MER

4. Distance Protection of Transmission Lines with High Levels of Series Compensation : A study on frequency and time domain communication independent distance protection for series compensated lines
Sammanfattning : Series capacitors are used in electric transmission lines to increase their power transfer capacity. They compensate for the inductive reactance of the line. They offer a useful alternative to building new lines, in view of economic and environmental constraints. LÄS MER
5. Protection Strategies to Mitigate Major Power Systems Breakdowns
Sammanfattning : This thesis deals with new methods to improve the performance of power system protection in the case of voltage- and transient instability. These methods are designed primarily to mitigate power system breakdown. Relay algorithms are proposed where conventional distance protection is combined with additional relay criteria. LÄS MER
