Description of the invention: [Technical field to which the invention pertains] The present invention relates to a wind power generation device that is activated by a breeze, in particular, a first and second path that utilizes two feeds into the mains, that is, A wind power generation device that can increase the wind energy utilization rate at a low wind speed. [Previous technology #?] In the past few years, due to the gradual generation of energy for the limited energy on the earth: the crisis is committed to research and development of alternative energy to replace existing energy, of which wind power is one of the main development priorities, however, the current wind power system There are still some problems in actual use. The wind power generator must overcome the static friction of the machine under the low wind speed to drive the generator to rotate. Therefore, once the wind can not drive the fan rotor to rotate, the power generation can not receive the energy of the fan rotor. Unable to convert its kinetic energy into power. i^, the general practitioner can not meet the needs of the user in actual use. [Summary of the Invention] = The main purpose of Ming is to use two feeds to the mains, Gulei Road, k彳, when the general wind speed is large enough, 'from the first road' to reach a low speed at low wind speed T or not yet L When the static friction is not running, the second path can be powered by electricity first, and the actuator is driven to generate the generator. 200916655 When the speed is released, the drive is cut off and restored to feed. Entering the first path of the city's electricity, this will increase the wind energy usage at low wind speeds. For the purpose of the above, the present invention relates to a force with a breeze start = an electric device, which comprises at least a fan blade rotor with a fan formed therein, the generator, a three-phase AC/DC rectifier, a DC/ The AC converter and the driver are formed by the first and second paths of the two feeds, wherein the first path is at a high wind speed, and when the blades of the blade rotor are rotated by the wind, The plunger synchronizes the generator to generate electricity. After the three-phase AC/DC rectifier is passed, the generator can supply sufficient voltage to the Dc/Ac feeder to rotate = the final parallel mains; if the low speed is reached at a low wind speed When the j friction is not running, the second path is first performed. First, a sampling mode that can reach the preset breeze starting point (Kick〇ff) and then selects the measured wind speed is selected. The mode determines whether the drive is started, and then the current wind speed is obtained by an anemometer, and the state of the fan is determined to be rotating or stationary by a tachometer, and the result is that the current wind speed and the state of the fan start the crying = Drive the generator' The fan is determined again when the rotational speed reaches a predetermined value if the radio ㈣n means, if the first and other rows whom judgment.
