Converter topologies for offshore wind farms must be designed taking into account reliability and size of the converter. Reduced matrix converter fulfill this two requirements and permits to built a series connected grid. The modulation of this converter can be done by space vector or carrier based modulation. Both types of modulations must be modified to accomplish the requirements of the three phase...
This work relates to the solution of reactive power problem in a line-commutated HVDC link. A series injection strategy has been formulated and the effects have been simulated indicating a significant reduction in reactive power consumption of the link. This would reduce the weight and volume of the capacitance required which is usually employed in such links thereby reducing the overall weight and...
This work attempts to explain reactive power consumption in a line commutated HVDC transmission system and suggests a possible solution to reduce it. A series injection strategy has been formulated using voltage-source converters and the effects have been simulated indicating a significant reduction in reactive power consumption by the converter terminal and consequently that supplied by the source...
This paper presents a concept of high frequency link for offshore wind applications based on a reduced matrix converter oriented to reduce the size and volume of the elements in the nacelle. A modular approach aimed at increasing reliability of the conversion system, which can be used in series or parallel connection of the off shore grid is also presented. Features of the proposed conversion concept...
