Sammanfattning : Cascaded H-bridge (CHB) converters are today considered the industrial standard for STATCOM applications, mainly due to their small footprint, high achievable voltage levels, modularity and reduced losses. However, there are still areas of research that need to be investigated in order to improve the performance and the operational range of this converter topology for grid-applications. LÄS MER
Sammanfattning : In the last decade, particular attention has been paid to the use of Modular Multilevel Converters(MMC) for grid applications. In particular, for STATCOM applications the phase leg ofthe converter is constituted by a number of single-phase full-bridge converters connected incascade (here named Cascaded H-Bridge, CHB, converter).

3. Modelling and control of a line-commutated HVDC transmission system interacting with a VSC STATCOM
Sammanfattning : The interaction of an HVDC converter with the connected power system is of complex nature. An accurate model of the converter is required to study these interactions. The use of analytical small-signal converter models provides useful insight and understanding of the interaction of the HVDC system and the connected system components. LÄS MER
Sammanfattning : This project deals with voltage source converters with energy storage capability. The main objective is to study the possible benefits of energy storage to a power system with a VSC as the interface between them. First of all, a converter control system is proposed for a two level VSC. LÄS MER
Sammanfattning : Static synchronous compensation (StatCom) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, StatComs are employed for reactive power support only. LÄS MER
