Technique analysis of off-grid wind power used for aluminum electrolysis

Two months of basic data which are in March 2008 and April 2008 about wind speed and its relevant output power of single wind driven generator have been selected and analyzed. A special situation that two wind driven generators supplied power for three aluminum electrolysis pots has been analyzed technically. In the analysis, a whole day has been divided into two periods which are day time and night time, different power supply mode will be selected according to particular cases.
