Embodiment 1
[0072] Embodiment 1: The wind power converter 1 provides the current conversion function for the wind power equipment, the IGBT module 2 converts the DC power generated by the wind power equipment into the AC power input distribution side, and the intelligent control module 3 sends control information according to the working conditions of the wind power converter 1 to the power adjustment module 4 to control the operation of the work adjustment module, and the power adjustment module 4 sends power adjustment information to the IGBT module 2 to control the operation of the IGBT module 2 .
Embodiment 2
[0073] Embodiment 2: The difference from Embodiment 1 is that the wind power converter 1 is electrically connected to a communication module 6, and the communication module 6 is signal-connected to a remote control module 5, and the remote control module 5 is electrically connected to There is a power adjustment module 4, the power adjustment module 4 is electrically connected with the IGBT module 2, the communication module 6 sends the working information of the wind power converter 1 to the remote control module 5, and the remote control module 5 transmits the remote control module 5 through a remote signal. The information is sent to IGBT module 2, and the work of IGBT module 2 is manually controlled.
Embodiment 3
[0074] Embodiment 3: The difference from Embodiment 1 is that the wind power converter 1 is electrically connected to a data monitoring module 7, and the data monitoring module 7 is electrically connected to a fault judgment module 8, and the fault judgment module 8 Electrically connected with a circuit breaker module 9, the data monitoring module 7 monitors and obtains key data of the wind power converter 1, and sends the data information to the fault judgment module 8 and the data backup module 11, and the fault judgment module 8 uploads the data according to the data monitoring module 7 The fault information of the wind power converter 1 is judged, and according to the judgment result, the control information is sent to the circuit breaker module 9 and the alarm module 10. The circuit breaker module 9 provides a circuit breaker function to make the wind power converter 1 disconnected.
