Optimum operating regimes for the ideal wind turbine

A Compact , Closed - Form Solution for the Optimum , Ideal Wind Turbine

The classical momentum solution for the optimum induced-flow distribution of a wind turbine in the presence of wake swirl can be found in many textbooks. This standard derivation consists of two momentum balances (one for axial momentum and one for angular momentum) which are combined into a formula for power coefficient in terms of induction factors. Numerical procedures then give the proper i...

Wind Turbine Transformer Optimum Design Assuming a 3D Wound Core

A wind turbine transformer (WTT) is designed using a 3D wound core while the transformer’s total owning cost (TOC) and its inrush current performance realized as the two objective functions in a multi-objective optimization process. Multi-objective genetic algorithm is utilized to derive Pareto optimal solutions. The effects of inrush current improvement on other operating and design parameters...
