Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] figure 1 It is the circuit block diagram of the wind power generator controller of the present invention.

[0027] Such as figure 1 As shown, the wind power generator 101 converts wind energy into AC power, and the rectifier circuit 102 converts the AC power into DC power for the load 103 . For example, the load 103 may include a storage battery, which receives DC power from the rectifier circuit 102 for charging; as another example, the load 103 may inclu...

Abstract

The invention discloses an aerogenerator controller and a control method, which solvethe problem of controlling accuracy of output power of an aerogenerator. The aerogenerator controller includes: a sampling circuit, which samples an electrical information from a load end and sends a sampling signal to a harmonic wave control circuit; aharmonic wave control circuit, which receives the sampling signal from the sampling circuit, monitors a power supply state of a load according to the sampling signal and outputs a harmonic wave control signal to a harmonic wave injected circuit; wherein the harmonic wave injected circuit is coupled to a winding of the aerogenerator, receives the harmonic wave control signal from the harmonic wave control circuit, and adjusts a harmonic wave injected into the aerogenerator winding according to the said harmonic wave control signal. This invention can control the output voltage and power of the aerogenerator at a high accurate level and do not need an unload device with a huge volume.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a controller of a wind power generator and a control method of a wind power generator. Background technique [0002] Energy shortage has become the primary problem faced by the whole world, and wind energy, as a clean energy, has been highly valued by all countries. my country has abundant wind energy resources, and the market prospect of wind power equipment manufacturing industry and related fields is very broad. [0003] The existing wind turbine controller must be equipped with an unloader. When the wind is strong or the battery is fully charged, the output power of the wind generator is controlled by unloading the power of the wind generator. Usually, the power of the unloader is twice the power of the wind generator. In the above method, the unloader is mainly composed of power resistors, through which the excess energy of the wind turbine is unloaded, so the temperature o...
