Problems solved by technology

[0004] However, the existing power modules can only automatically adjust the power through smart devices. During the adjustment process, the power fluctuates frequently. Moreover, when the wind power converter fails, the wind power converter cannot be shut down in time, and the fault cannot be recorded. information, it is not easy to carry out maintenance

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.

Abstract

The invention belongs to the technical field of wind power converters, and particularly relates to a power module and method of a wind power converter, and the power module comprises the wind power converter which is connected with an IGBT module and an intelligent control module, and the wind power converter is used for providing a conversion function for wind power equipment; the IGBT module is connected with a power distribution side and the power adjusting module, and the IGBT module is used for converting direct current generated by the wind power equipment into alternating current and inputting the alternating current into the power distribution side; and the intelligent control module is connected with a power adjustment module, and the intelligent control module is used for sending control information to the power adjustment module according to the working condition of the wind power converter so as to control the working adjustment module to work. According to the power module of the wind power converter, the output power of the wind power converter can be automatically adjusted, the fluctuation condition of the power is reduced, when the wind power converter breaks down, the wind power converter is automatically turned off, fault information is recorded, and maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of wind power converters, in particular to a power module and method of a wind power converter. Background technique [0002] At present, with the rapid development of the economy, energy has become an important strategic resource. Traditional coal, oil, and natural gas are non-renewable energy sources that do not have the ability to be used sustainably. In the case of continuous reduction of traditional energy sources, wind energy, solar energy, etc. The new energy represented by wind energy has become a new choice, and the new energy strategy has also been raised to a new level. Among them, the development and utilization of wind energy has received extensive attention and vigorous development. In a wind turbine, wind energy is absorbed by the impeller and blades and converted into changing rotational kinetic energy. The rotational kinetic energy is transformed into electric energy with voltage and frequen...
