The invention discloses an apparatus and a method of independent wind power driven seawater desalination. The method comprises the steps that: step one, establishing an independent grid: an independent grid is established through a bi-directional inverter by using electric energy from a storage battery; step two, wind power grid-connecting: electric energy generated from each aerogenerator is delivered to the independent grid through aerogenerator controllers and grid-connecting inverters; step three, load connecting: water supplying pumps, high pressure pumps and reverse osmosis membrane components are connected to form independent membrane modules, load circuits of the independent membrane modules are connected in parallel, and then connected to an electric output of a power system; step four, system coordination dynamic controlling. Previously, wind power driven seawater desalination requires large capacity storage batteries for ensuring the stability of power supply. With the present invention, the technical problem is solved, and a novel independent wind power driven seawater desalination mode is provided. According to the present invention, energy cost in fresh water producing with the present apparatus is substantially lower than that with systems of other similar types. Thus, the apparatus and the method have good prospect to be developed and applied in the field of seawater desalination.
