Embodiment Construction
[0009] Such as figure 1 shown. A wind-driven generator over-wind speed protection and control method, the wind-powered generator includes a sideways rotator, a machine head mounted on the rotator driven by the rotator, rotating blades installed at one end of the machine head, and controlling the movement of the gyrator The steering motor is characterized in that: a wind speed sensor is set on the wind power generator, the signal output end of the wind speed sensor and the steering motor control end are respectively connected to a PLC, and the wind speed warning value is preset in the wind speed sensor. When the wind speed sensor detects When the external wind speed is greater than or equal to the preset wind speed warning value, the wind speed sensor sends an over-wind speed signal to the PLC. After receiving the over-wind speed signal from the wind speed sensor, the PLC sends an instruction to the steering motor to control the steering motor to drive the rotary body to the si...

The invention discloses a super-wind speed protection and control method of a wind driven generator. According to the super-wind speed protection and control method, when a wind speed sensor detects that an external wind speed is greater than or equal to a preset wind speed early-warning value, the wind speed sensor transmits a super-wind speed signal to a PLC (Programmable Logic Controller), and the PLC is used for controlling a directional motor to drive a rotating body to incline to one side by 90 degrees so that the generator stops working. According to the super-wind speed protection and control method, the change of wind speed can be monitored in real time, when wind speed is too fast, the wind driven generator stops running timely, the problem that the internal parts of the wind driven generator are damaged due to too fast wind speed is avoided, and the safety of generator operation is improved.
Description
technical field [0001] The invention relates to the field of wind power generator control methods, in particular to a wind power generator over-wind speed protection control method. Background technique [0002] A wind turbine is a device that uses wind energy to generate electricity. It includes a movable rotator installed on the nose, a steering motor that drives the rotator to move, blades installed on the nose, and tail fins installed on the blades. , wherein the central rotating shaft of the blade is connected with the generator rotor in transmission. The blades drive the machine head to rotate under the action of wind, so that the rotor in the generator rotates to generate electricity. In the prior art, the wind speed often causes damage to the internal components of the wind generator when the wind generator is working, which affects the safe operation of the wind generator. Contents of the invention [0003] The purpose of the present invention is to provide a w...
