(TU Delft DC systems, Energy conversion & Storage) Dong, J. (TU Delft DC systems, Energy conversion & Storage) Polinder, H. (TU Delft Transport Engineering and Logistics) Ferreira, Jan Abraham (TU Delft ESE Programmes) Date 2018 Abstract Modularity is promising from a view to increasing turbine availability through fault tolerant operation as well as reduced downtimes, especially for offshore wind turbines. This paper focuses on a quantitative analysis of large scale (or extreme) modularity in power electronic converters of wind turbine generator systems. It uses mathematical models to investigate the effect of the choice of module number on the availability of a converter. It further analyses the availability in conditions where increased levels of modularity lead to a reduction of failure rates in the system. The paper extends this analysis by quantifying the benefits for a 10MW case study turbine. Finally, it concludes that extreme modularity holds merit only when it is accompanied by a reduction in failure rates.
