High Voltage Power Converter For Large Wind Turbine

Abb wind turbine converters for a better wind economy.

High voltage power converter for large wind turbine. The wind turbine generator system requires a power conditioning circuit called power converter that is capable of adjusting the generator frequency and voltage to the grid. T1 high voltage power converter for large wind turbine. In an onshore horizontal axis wind turbine generator and converter are usually in the nacelle on the top of the tower while the grid step up transformer is placed at the bottom. The selection of the right converter is critical in the turbine design and for a higher return on investment.

The conventional low voltage power conversion system will suffer from a high transmission current which significantly increases losses and cost of the cables as well as voltage drop. T1 high power density power electronic converters for large wind turbines. One promising solution for future large wind turbine power conversion is to use medium voltage power conversion systems for high efficiency and high power density e g. Au senturk osman selcuk.
