Wind energy converter cooling solution

By exciting the rotor of the doubly-fed asynchronous wind generator, the wind power converter makes the amplitude, frequency and phase of the output voltage of the stator side of the doubly-fed generator the same as that of the power grid, and the active and reactive power can be independently decouped according to the needs. Converter control of doubly-fed asynchronous wind turbine realizes soft grid-connection, and reduces the adverse effect of grid-connection impulse current on motor and power grid. It can be said that the stable operation of wind power converter directly affects the stability of power grid. How to ensure the normal operation of the wind power converter, heat dissipation is an indispensable link.


Zerode thermal is rooted in the research and development of heat dissipation in the field of new energy. In the field of wind power converters, Geoude Thermal carries out strategic cooperation with many domestic and foreign wind power converters manufacturers to provide reliable heat dissipation technical support for wind power converters, inverters, motors, etc. Zerode Thermal achieves integrated and holistic service requirements from thermal design and simulation of heat dissipation systems to the production of heat sinks. It has been widely praised by wind power manufacturers.
