Problems solved by technology

[0003] At present, the control of the unloading load is one-time access or removal of the whole, or simply continuous control of a single load. This method will cause a large impact on the switching tube in an application with a slightly larger power. current, so it will increase the difficulty of selecting the switch tube and increase the cost of the product

Abstract

The invention relates to a high precision control device of the windmill generator damp load. The high precision control device comprises a windmill generator, a protection circuit, a rectifying tube, the damp load, an absorbing circuit, a switching element and a control module circuit, wherein the three-phase output terminals of the windmill generator are directly connected with the rectifying tube and the protection circuit; one end of the damp load is connected with the positive electrode of the rectifying tube adopting the direct current output, the other end of the damp load is connected with one end of the switching element; and the other end of the switching element is connected with the negative electrode of the rectifying tube adopting the direct current output. By using the device of the invention, the control precision of the damp load can be greatly increased, the selection difficulty of the switching tube can be reduced and the product cost can also be reduced.

Description

technical field [0001] The invention relates to the field of wind power generation systems, in particular to a device for high-precision control of unloaded loads of wind power generators. Background technique [0002] In recent years, all sectors of society are advocating low-carbon life, so the use of green and environmentally friendly energy has attracted more and more attention. Wind power is one of the clean energy sources that are focused on development. Wind power uses wind to drive the blades of the generator to rotate. , a way of converting kinetic energy into electrical energy. In most applications, the unstable energy generated by wind power generation needs to be stored in the battery pack through the charge controller. At the same time, if the voltage or current stored in the battery is detected to be too high, the system will turn on the unloading load, and use the unloading load to release the excess electric energy, thereby suppressing the output voltage and...
