Wind power generator

A method for operating a fixed angle wing lift type horizontal shaft wind power generating device comprising a permanent magnet type generator for generating in connection with a rotation shaft of a rotation wing which is rotated in the forward direction by the wind, a switch unit for switching the generator to a motor, a wind velocity measuring unit, a first time counting unit and a second time counting unit having a time counting period longer than a time counting period of the first time counting unit, comprising:

• operating a start assisting function when the wind velocity measuring unit detects a wind velocity lower than a predetermined velocity;
• continuing operation of the start assisting function only during a time counting period of the first time counting unit;
• suspending the operation of the start assisting function during a time counting period of the second time counting unit and switching the motor to the generator by the switch unit;
• monitoring whether the output voltage from a coil stator of the generator is equal to or more than a predetermined voltage during the repetition process;
• charging a battery with the output voltage of the generator when having detected a voltage higher than the predetermined voltage in the voltage monitoring process;
• and
• repeatedly changing operations of the start assistance process and the generation restoring process, the rotation rate of the rotation wing being swiftly increased above a predetermined value,
• wherein a regular rotation can be started by the inertia of the start assisting rotation even at the time of winds too weak to rotate an ordinary fixed angle wing lift type horizontal shaft wind power generator alone.
