1. Extreme Load Conditions for Wind Powered Direct Drive PM Generators
Sammanfattning : Wind energy is a rapidly growing energy source with vast potential. Vertical axis wind turbines could be more cost-effective than the three bladed horizontal axis turbines that dominate today. LÄS MER
2. A Generator Perspective on Vertical Axis Wind Turbines
Sammanfattning : The wind energy conversion system considered in this thesis is based on a vertical axis wind turbine with a cable wound direct drive PM generator. Diode rectifiers are used to connect several such units to a single DC-bus and a single inverter controls the power flow from the DC-bus to a utility grid. LÄS MER
