Description: The course includes:
• a thorough analysis of main commercial wind-generator systems in their topologies for high ratio gear, one stage gear and gearless, performance, merits and demerits
• introduces a fairly general (but practical) model and electromagnetic design methodology for variable speed wind-generators with application to case studies for :
• cage- rotor induction generator systems, wound-rotor induction generators, PM synchronous generators, DC-excited synchronous generators
• shows key FEM results for design validation
• discusses an optimal design methodology with case study results
• shows performance, size and cost comparisons between various solutions
• introduces the main power electronics control systems-with dual PWM converters with their vector and direct power control strategies, with results on case studies with non-faulty and asymmetric voltage sags
• presents new (one with PMs and one PM-less) potential, lower weight & higher performance large power wind-generator solutions for high ratio gear, single stage gear and gearless topologies with:
• principle, merits and demerits, preliminary sizing, FEM key results to illustrate their capabilities
• presents new power electronics converters (matrix, selfboosting etc) amenable to wind generators of the future ,with preliminary results on their performance
• presents different control methods during normal operation and ride-through operation
• summarizes main existing and possible future trends in wind-generators systems related to their design and control and identifies new subjects for future research in the field
