The design and production of air-cooled and water-cooled reactor (patent products) and control transformers are widely used in doubly fed and direct drive wind power converter systems, which have been widely used and approved in the industry.
As a clean renewable energy, wind energy is being paid more and more attention from all countries in the world. The wind energy resources are rich in China. In recent years, the national policy also supports the wind power industry.
The wind power converter uses a three-phase voltage type - direct - AC bidirectional converter technology, and the core control adopts a "double DSP full digital controller" with a fast floating point operation capability; the stator flux constant vector control strategy is implemented in the generator's rotor side converter and the power grid side converter is real. The grid voltage oriented vector control strategy has the functions of input and output power factor adjustable, automatic soft grid connected and maximum power point tracking control. The power module uses IGBT power devices with high switching frequency to ensure good output waveforms.
Appropriate voltage regulation measures should be adopted, such as series compensation, transformer installed with on load voltage regulating device, installing synchronous phase adjusting camera or electrostatic capacitor.
